and netbsd32_compat40 packages. The compat40 packages are currently
built by comparing the 4.0 release against the 20071230 version of
HEAD.
Commit approved by <agc>.
Emulate the speaker port's refresh clock bit. This is supposed
to toggle between 0 and 1<<4 every 15 microseconds. XXX: We use
gettimeofday() in the real machine instead of a monotonic clock
in the virtual machine, and we are a bit sloppy about the 15
microseconds. This should be good enough for crude loops that
measure approximate delays by counting how often this line toggles.
Bump PKGREVISION to 1
0.8.5:
Fixed a crashing bug when loading an uncompressed file and using the automatic IPS-patching feature when mmap() is available.
PCE, PC-FX: All SCSI CDROM commands are now logged in the debugger's log viewer(when logging is enabled, of course).
Added group support to the debugger's log viewer.
PC-FX: Renamed the type of BIOS ROM font calls in the debugger's log viewer from "BIOS" to "ROMFONT".
PC-FX: BIOS filesystem syscall(for backup memory access) calls are now logged in the debugger's log viewer.
PC-FX: Added internal backup memory and external backup memory address spaces to the debugger's memory editor.
PC-FX: In the 263-line mode, line 262 is now reported as being during blanking time(as on a real PC-FX). Fixes the annoying transparency layer
flickering and other weird graphical glitches in Der Langrisser FX.
Added setting "filesys.disablesavegz", to disable gzip compression when saving save states and backup memory.
(In the case of backup memory, disabling gzip compression isn't supported for GB yet)
0.8.4:
PC-FX: Some RAINBOW registers weren't being reset on emulated system reset. Fixed.
PC-FX: Added dummy support for the external bus reset register.
PC-FX: Altered the way garbage data is handled by RAINBOW to fix a graphics bug in the Tengai Makyu options screen.
PC-FX: Reworked a large part of the KING SCSI emulation code, and parts of the CDROM device emulation code. Previously non-working-at-all games
"Battle Heat" and "Tengai Makyu" work now.
The non-anime game mode in "Tyoushin Heiki Zeroigar" works now. "Der Langrisser FX" no longer locks up if you skip the intro movie.
"Yuna FX" no longer locks up in one of the intro movies.
These changes will cause some save state incompatibilities with previous versions of Mednafen.
(Some of the SCSI changes also affect the PCE CDROM emulation, which may also result in save-state incompatibility issues, particularly if
the save state occurred during a CDROM data transfer operation.)
PC-FX: Added setting "pcfx.cdspeed". If you want to change this, read the documentation first!
Cleaned up the video deinitialization code slightly, and fixed a few bugs in the OpenGL deinitialization code.
PC-FX: Reads from the dummy KING register 0x07 will now return 0xFF, per the devkit docs.
PC-FX: Reads from KING register 0x0B will now return the "DMA end" bit in D0 set correctly(at least, according to the developer docs).
Fixed a compilation error after running configure with --disable-nes.
PC-FX: Reads from I/O port 0xFC0 will *now* return the current timer counter value. The switch statement mask value was wrong...
Removed the warning in the documentation about error correction of raw data track rips, as Mednafen will now perform simple correction
using the EDC and L-EC data(since 0.8.4-rc3). This could conceivably cause problems with naive hacks/translations/patches that neglect to update
the EDC and L-EC data, so it can be disabled by setting the setting "cdrom.lec_eval" to 0.
L-EC correction is based off code from dvdisaster(http://dvdisaster.net/).
PCE, PC-FX: Removed some debug printf()'s that were left in 0.8.4-rc3 by mistake.
0.8.4-rc3:
PCE: Added preliminary(it works, but the code needs to be cleaned) ADPCM support for HES rips.
PCE: Interrupts will be enabled with a CLI after a HES' init routine is called, to fix rips that neglect to do it themselves.
PCE: Added support for HES rips that try to write data where it really shouldn't be written(some CD-ROM game rips do this), though a warning
will be printed the first time this occurs after loading.
PCE: Added sanity checks to the HES loader to prevent crashes if invalid data is present.
PCE: Reads from the I/O port will now return D7 as clear when emulating a PCE CD game.
PCE: ADPCM RAM is now reset(to 0) on emulated PCE reset.
PCE: Sprites trying to pull tile data from $8000-FFFF of VRAM will now be invisible(probably not correct, but trying to emulate indeterminate
effects is too difficult :b). Fixes a minor sprite garbage issue in Camp California.
PCE, PC-FX: Fixed VRAM DMA source/dest increment/decrement bits(the source and dest were flipped). Fixes a problem with Fushigi no Yume no Alice.
Moved some code in the source root directory to appropriate subdirectories.
Added setting <system>.debugger.disfontsize, valid settings being "xsmall", "small"(default), "medium", and "large", to control the font
size used to draw the disassembly text. Note that there may be overlap with other parts of the debugger at font sizes larger than the default.
Refactored a few address space and register group debugger support functions out of individual system code.
Fixed various low-impact memory leaks.
The version of Mednafen last run is now stored in the configuration file as a comment(this will be necessary for changes in 0.8.5 or later
that will involve proper escaping/unescaping and quoting of strings, to prevent problems with extra whitespace added by manually editing
the configuration file).
Fixed state rewinding on big-endian machines, and removed some unnecessary operations from the state rewinding code path.
Mednafen will now refuse to try to load ROM images larger than 64MiB, as a sanity check.
mmap() and madvise() will now be used to load ROM images, assuming they're available(UN*X only, generally).
Errors during automatic IPS patching are now fatal.
Sped up loading gzip'ed ROM images.
Removed a global variable from the NES emulation code that had invaded state.cpp. Though, this makes the error message when trying to use
save states with authentic Game Genie emulation very unhelpful...
GBA: Added support for loading a real GBA BIOS ROM image, using the setting "gba.bios".
GBA: Added the ability to specify the backup memory type for games by creating a file with the same name as the ROM image,
with the extension replaced with "type", in the "sav" directory under the Mednafen base directory.
Example: SexyPlumbers.gba -> SexyPlumbers.type
One or more of the following strings(on separate lines) may appear in the file:
sram
flash
eeprom
sensor
Additionally, the flash size can be specified by specifying the size(real size, or divided by 1024) after the type, like "flash 128" or
"flash 131072".
PCE: Improved noise LFSR and volume emulation, thanks to cgfm2 for the detailed information.
0.8.4-rc2:
Added meaningful descriptions to the command.* settings.
PC-FX: Added an experimental feature to use mmap() to create a virtual 32-bit address space to speed up V810 instruction reads.
Enable by setting "pcfx.use_mmap" to 1. Of course, it won't work on 32-bit CPUs! Please read the documentation, there are caveats!
PC-FX: Removed some redundant logic in the KING BG 8x1 drawing functions.
PC-FX: FX VCE and VDC port access are now emulated as 16-bit, as in the real PC-FX, instead of 8-bit.
PC-FX: Altered the debugger's memory peek and disassembly functions to not read the emulated memory map in the 0x80000000-0xEFFFFFFF region.
(Reading those addresses can cause side effects, and this is a temporary workaround)
PC-FX: Changed the V810 memory read handlers to read RAM faster than BIOS ROM. This will probably increase host CPU usage while in the BIOS
loading screen, but decrease it in the actual game.
PC-FX: Altered the V810 opcode fetch logic to do 16-bit reads instead of 32-bit, fixing potential crash issues
when Mednafen is run on CPUs that don't support unaligned memory accesses.
PC-FX: Factored-out a few address masks in the memory read and write handlers.
PC-FX: Replaced most of the V810 signed-variable bit-size converting code that uses conditional branches to code that uses 2 shifts,
taking advantage of modern 2's-complement CPU's arithmetic right-shift capabilities. It reduces generated machine code size slightly,
and should provide a slight speed boost as well.
PC-FX: Optimized V810 address mode decoding by removing an unnecessary conditional jump.
Added an important warning to the documentation regarding Mednafen's ripped CD image support:
Mednafen does *not* correct bit errors in the user data of "raw" data track rips. It is strongly recommended to use
"cooked" data track rips(2048 bytes/sector for mode 1, not counting any subchannel data) with Mednafen.
PC-FX: Improved exception handling, and added untested emulation of the TRAP instruction.
Debugger: Rewrote the memory load and dump functions to be faster, and also to fix a bug in the load function that would
trash memory if the user tried to load more data than the specified file contained.
Debugger: Using the Goto function will no longer cause memory edit mode to be exited.
Debugger: Fixed a bug that occurred when entering a prompt(goto, change charset, etc.) while in editing mode, that caused
keyboard focus to be misdirected.
SexyAL: The ALSA driver will try to set smaller period sizes when lower playback rates are used.
GBA: Changed the heuristics used to detect SRAM/Flash usage, though they're still not perfect...if a game tries to use flash
memory improperly, it could be detected as using SRAM instead, or silently corrupt parts of flash memory...
GB: Fixed sound register initialization on reset, fixes missing sound in A Boy and His Blob
GB: Slightly increased the contrast of GBC colors.
GB: Reworked blitting of mono GB colors for future features.
GB: Removed a redeclaration of a variable in the same scope in a function in gfx.cpp.
Debugger: Fixed PCE VRAM breakpoints to work with block memory transfer instructions.
Debugger: Fixed parsing of single-address breakpoints after range breakpoints.
Mednafen will now print out SDL version information when it starts.
(The Win32 build will now be distributed with SDL 1.2.12)
Debugger: Fixed -/+ opacity adjustment to not be done when entering text(such as in a dialog).
Debugger: Fixed null termination of the ASCII string buffer displayed in the memory watch section.
PCE, PC-FX: Fixed the frequency of the highest-frequency noise generation register setting, hopefully!
PCE, PC-FX: Changed the LFSR to 16-bit, and to use a maximized tap configuration, to make the noise sound a bit closer to a real
PC Engine's(at least, in my opinion! It still sounds slightly more bassy than a real PC Engine, but that might be due to filters
on the PC Engine's sound output...).
Non-power-of-2-sized-textures will not be used when a pixel shader is selected and enabled, to prevent a severe graphical corruption
regression introduced in 0.8.3-beta. I'm not sure if it's a problem with Mednafen's pixel shaders or the graphics card...
SMS: Fixed soft reset.
SexyAL: Removed smallc.c, and modified the OSS driver to use snprintf() instead of the single function smallc.c provided.
SexyAL: "sexyal.h" is now included before all other header files.
SexyAL: Revamped parts of the ALSA driver to fix reported lockup issues under certain conditions.
0.8.4-rc1:
Added preliminary support for inputting text directly into the selected address space in the debugger's memory editor.
Moved the temporal video blurring code in mednafen.cpp to vblur.cpp
Added settings "filesys.snap_samedir", "filesys.sav_samedir", "filesys.state_samedir", and "filesys.movie_samedir", default 0, that when
set to 1, will read/write the respective files from/to the same directory the game was loaded from. If you want
to use these, PLEASE read the documentation first, there are caveats!
PCE CD, PC-FX: Added support for MS WAV file offsets and lengths in TOC files.
PCE CD, PC-FX: Fixed a bug that caused CD-DA playback to be off by one sector(the first sector specified was being skipped).
Began work to allow settings to be temporarily overridden during netplay and movie playback.
PCE, PC-FX: Added settings "pce.disable_softreset" and "pcfx.disable_softreset", default 0, which when set to 1 will disable
simultaneous pressing of RUN and SEL. The current implementation kind of abuses the driver-side code that disallows opposing diagonal buttons
being pressed at the same time, so if we ever change that (undocumented) feature to go with the last-pressed direction rather than
clearing both, the description of these settings in the documentation will need to be updated.
PCE CD, PC-FX: Read operations and CD-DA playback will now be stopped when the RST signal is asserted(fixes soft reset issues on PCE CD
games).
0.8.3-beta:
Fixed an OpenGL function typedef in drivers/opengl.h.
PC-FX: Writes and reads to the KING and FXVCE chips "mapped" in parts of 0xA0000000 through 0xBFFFFFFF will now go through the respective
data port write handlers, instead of directly to KRAM or palette RAM.
If non-power-of-2-sized OpenGL textures are not available, and bilinear interpolation or a pixel shader is enabled, and the emulated
system resolution changes(such as on the PCE), two lines of black pixels will be written to the texture buffer to prevent the display
of multi-colored garbage at borders, though the right+bottom borders will still be slightly darker than they should be...
PC-FX: Added support for VDC data port writes via writes to 0xB4000000-0xB7FFFFFF and 0xB8000000-0xBBFFFFFF in the V810's
memory map. Fixes major graphical problems in "Super Power League FX".
Updated the srwcompressor description in mednafen.cfg.
PC-FX: KING BG1-3 scroll registers are now emulated as 10-bit instead of 11-bit(BG0's are still 11-bit), and BG1-3 virtual
screen size is now limited to 512x512(BG0 is still 1024x1024), per the official developer documents.
Non-power-of-2-sized OpenGL textures will now be used if the "GL_ARB_texture_non_power_of_two" extension is detected.
Fixed a bug that sometimes would cause black screens when using the "sdl"(non-default) video driver(SDL surface per-pixel alpha blending
was enabled when it shouldn't have been).
PCE: Fixed a line clearing bug when BG is disabled that was causing some minor graphical garbage on some games that
use multiple horizontal resolutions per frame.
Changed some nonsensical #ifdef statements that were intended to always evaluate as false with "#if 0".
Renamed SYSTEM_CLOCK to System_Clock in scsicd.cpp to work around a potential macro conflict on OSX.
PC-FX: Added partial support for NEC's "scan" SCSI command, used in the BIOS' CD-DA player screen.
PC-FX, PCE CD: Revamped parts of the subchannel emulation code. The PC-FX BIOS CD player screen's time display works now. Also, an important
note regarding cdrdao "TOC" files and "RW_RAW" subchannel data was added to the documentation.
PC-FX: Fixed a bug in the KING BG0 scrolling+rotation code for 16-color and 4-color backgrounds with BATs that was causing graphical
corruption in the PC-FX BIOS CD player screen.
Fixed a compilation error when --disable-debugger was passed to the configure script.
0.8.2-beta:
Added blargg's experimental blz compressor, for use with state rewinding(change the setting "srwcompressor" to use it).
(This was added a while back, after 0.8.1, but I forgot to document it)
SMS,GG: Added missing default key configurations.
PC-FX: Added untested emulation of scaling+rotation in 4-color KING BG mode.
PC-FX: Added emulation of scaling+rotation in 16-color KING BG mode. Fixes a problem with the background in the last stage of Zenki.
PCE: Added VRAM size constants to the beginning of vdc.cpp, and modified the code to use them, to allow a certain crazy person to compile
a custom version of Mednafen which emulates extra VDC VRAM.
PCE: Removed 0xEB as SBC immediate in the disassembler(it was left over from the 6502 disassembler).
Changed setting type of setting "vdriver" to a string, with possible values "opengl" and "sdl"(and "0" and "1" for backwards compatibility,
of course).
PCE: Set the default char set in the debugger's memory viewer to shift_jis.
PCE: Fixed a missing #include <iconv.h> in debug.cpp.
2007-6-17:
PC-FX: Improved VCE<->VDC<->KING scanline timing to fix a lockup issue in Anime Freak Vol 4(polling the FX VCE raster counter register
vs VDC VBlank IRQs). Unforunately, this change has caused some 1-line graphical glitches in games that do "raster effects". This
may be solved once/if V810 emulation has accurate cycle counts, which would require emulating instruction cache and prefetch logic. -_-;
Fixed branch traces display in the debugger, it was broken to only display half of them twice sometime since 0.8.1.
PC-FX: Optimized RAINBOW JPEG-like decoding by using a static implementation of bit fetching functions(instead of a class).
PC-FX: Added untested emulation of the CAXI V810 instruction.
PC-FX: The RAINBOW transfer block count register is now emulated as being 5-bits instead of 16-bits, fixes screen issues(blue blue!)
after defeating the snake monster in Zenki.
PC-FX: If a KING BG is set to BAT+CG mode, but is missing a BAT fetch microprogram, it will now be drawn in CG mode(previously, the BAT
data was simply being forced to 0, which was wrong). It's confirmed on a real system. Fixes missing graphics in "Tonari Princess no Rolfee".
PC-FX: Fixed transparency testing with 16M color KING backgrounds(only 1 Y component of every 2 pixels was being checked, now
both are checked).
PC-FX: Implemented back cellophane support. Fixes fadeouts in "Lunatic Dawn", fadeins in "Team Innocent", and screen darkening issues
during dialogue in "Last Imperial Prince"(and also exposes a bug that LIP probably has on a real system too, wherein CCR isn't reset
to black after the dialogue is over, leaving the upper and lower parts of the screen outside the play area slightly dark greenish).
The hindmost color when mixing the layers is now set to palette entry #0, except when all layers are disabled(set to black),
or front cellophane(set to black) or back cellophane(set to value in CCR) is enabled.
PC-FX: Added emulation of the expansion backup RAM. While not particularly necessary since Mednafen already emulated backup memory
separately for each game, it does give a few extra save slots to some games(such as Miraculum ^_^).
Added opacity control(-/+) to the debugger.
Added an always-on zero page view to the CPU debugger for NES and PC Engine.
Reduced the size of the game thread event queue to a somewhat saner size, and added extra buffering so that its mutex is only locked for
a minimal amount of time to eliminate the chances of deadlock with this mutex.
GBA: Fixed a bug that caused only half of the legacy wave sound channel's sample data to be saved.
GB: Updated to Gb_Snd_Emu 0.1.5, fixes hanging note problems on some games, and cleaned up the sound save state code.
2007-5-30:
Added preliminary Sega Master System and Game Gear emulation based off of SMS Plus.
Factored the remaining state rewinding code out of the individual systems' code.
Fixed a minor visual bug when using state rewinding(also with save states, but it's not really visible) with the NTSC blitter.
Simplified how state rewind requests are passed to the emulation code, and fixed a small bug when using state rewinding with
frame advance(now, a rewind will only occur if the state rewind button is held down while the frame advance button is pushed).
Changed a local variable name in selblur.cpp to fix compilation on OS/X(and maybe PPC in general?), thanks to Matt Beaumont
for pointing out the conflict with a definition in altivec.h.
PCE: Fixed cycle counts for BRA and BSR(they were 1 too high).
PC-FX: Reads from I/O port 0xFC0 now return the current timer counter value.
Parameters to MDFNI_Emulate() and the internal system Emulate() functions are now passed through a structure, to allow
for easier future expansion.
PCE, PC-FX: Fixed audio track reading from physical CDs on big-endian platforms.
NES: Fixed a bug that caused an emulator crash if Game Genie-style cheats were enabled at the same time as authentic Game Genie
emulation was enabled.
Added setting "srwframes", which controls the number of save states to keep when state rewinding is enabled.
Debugger: Fixed a bug that caused a crash if a PC breakpoint was triggered while the debugger screen was disabled.
Added an experimental logging feature to the debugger, currently only used by the PC-FX emulation code, to log CD-ROM read commands
and calls to the PC-FX BIOS' glyph bitmap address function, both of which should be quite helpful in translation work...
PCE, PC-FX: Moved the mouse sensitivity adjustments to the driver side to fix mouse emulation with network play and movies
when using non-default pce.mouse_sensitivity/pcfx.mouse_sensitivity settings.
Added a few more entries to the in-emulator help screen.
PC-FX: Increased the keyport latch delay, and added emulation of the PC-FX mouse.
PC-FX: The keyport data ready flag is now reset only on low reads from the keyport data registers.
PCE: Fixed disassembly of the BSR instruction.
NGP: Fixed Z80 emulation cycle counts(they were far too low), and fixed emulation of the EI delay.
GB: Reworked various things, including Z80 interrupt and HALT emulation. GameBoy emulation will be a bit more CPU intensive now,
and save states from older versions won't work with this version(sorry!). These changes could easily break some games, but...at least
"A Boy and His Blob" works now!
GBA: Changed the file type detection code to reduce the chance of false positives.
PCE: Files with the extension "sgx" will now be treated as raw SuperGrafx ROM image files(AKA SuperGrafx emulation will be enabled).
NES: Refactored the file type detection code, so that emulation data structures and memory won't be initialized unless it's
a recognized file type.
NES: NSF(but not NSFE) game/album name, artist, and copyright strings are now trimmed of leading and trailing whitespace.
Added MDFN_trim(), MDFN_rtrim(), and MDFN_ltrim() functions.
WonderSwan: Fixed a buffer overflow bug in the sprite drawing code.
GBA: Flash and SRAM save games are now stored gzip-compressed.
PCE: Fixed raw bytes display of relative branch instructions in the disassembler.
PC-FX: Added CD-ROM data tracks to the memory debugger/viewer, read-only, however.
The selected character set in the memory debugger/viewer will now be saved for that emulated system when exiting.
Fixed text search in the memory debugger/viewer(iconv() was being called before the variables passed to it were initialized, oopsie).
Simplified the scrolling code in the memory debugger/viewer, the line containing the cursor will now always be centered vertically
on the screen.
PCE: Fixed an ambiguous if() statement in huc.cpp in the BRAM emulation code.
GB: Fixed a semi-ambiguous boolean math statement in the cpu emulation code.
Fixed an ambiguous else statement in the throttling code in drivers/main.cpp
NGP: Neo Geo Pocket emulation code is now compiled with -fno-strict-aliasing to work around issues in the TLCS-900h code.
GBA: Removed unused ELF code.
Fixed some implicit conversions of const char * to char *. (stupid putenv() prototype grumble mumble)
<stdlib.h> is now included in "mednafen.h", added notes to README about system header files automatically included,
and removed inclusions of such header files in source code files that include mednafen.h(most do, and should). This change
was brought about by gcc 4.3...it may not be the best way in regards to compile-performance wise, but it is more convenient
and safer than #include'ing the system headers manually(and forgetting to >_>).
Modified instances of "Makefile.am" to stop including the top directory in the include search path, and removed the symlink of
config.h to include/config.h, and fixed the references to "config.h" in intl/Makefile.in.
PCE: Made hes.cpp use MDFN_de32lsb() and MDFN_de16lsb() from endian.cpp.
PCE: Changed some instances of free() to MDFN_free().
GBA: Un-inlined the CPUWriteMemory() function.
GBA: Rewrote parts of the save-game(flash, eeprom, sram) code to make more sense! EEPROM data is now stored with a file extension "eep".
because those NetBSD releases didn't yet support amd64.
Before this change, pkgsrc would still try to install these packages
on amd64 if you manually entered the package directory and ran "make
install" because amd64 supports netbsd-i386 emulation.
PKGNAMEs. The packages in suse91_* and suse91_32_* didn't do that.
One effect of this was that the pbulk framework didn't record the
packages from both directories. It only took the first one, which
happened to be the suse91_32_* (which aren't available for i386). The
others were disarded, so effectively all Linux binary packages were
skipped.

"immediate" versus "lazy" evaluation of the value. Just explicitly
define a variable (COMPAT_PKG) that holds the value that's needed in
each of the compat* packages, and use it within Makefile.common.
This was an attempt to solve PR pkg/36863, but it doesn't look like
pkglint or lintpkgsrc understand this more straightforward variable
construction either.

may be defined after the inclusion of compat_netbsd/Makefile.common in
a package Makefile. This should fix the problem (reported in private
by Juan Romero Pardines) where the "-extras" packages did not have a
version number in PKGNAME.
This release fixes a few bugs that slipped through when releasing 0.71.
Here a list of the changes:
* Fixed unitialized variable in joystick. (Fixes crashes on Vista and Mac OS X)
* Some bugfixes and speedups to the 64 bit recompiling core.
* Fixed sign flag on soundblaster dma transfers (Space Quest 6 intro)
* Fixed a bug in keyboard layout processing code and fixed certain layouts.
* Fixed Dreamweb.
* Improved speed unlocking when running cycles=max.
* Fixed a crash related to the tab completion in the shell.
* Improved aspect correction code. Should now be like how a real monitor handles it.
* Fixed a bug in the xms status report code. (Blake Stone 1.0 shareware)
* Added a lot more keyboard layouts.
* Fixed crash related to changing the scaler before a screen was created.
* Hopefully fixed compilation on *bsd.

containing the paths to font directories for font packages installed
through pkgsrc. This allows Linux packages that use fontconfig to
locate fonts to actually find them when X11_TYPE != "native".
This should fix PR pkg/35160 and PR pkg/35505.
Bump the PKGREVISION.
of an emulated operating system. Instead of proliferating things like
SUSE_VERSION_REQD, NETBSD_VERSION_REQD, SOLARIS_VERSION_REQD, etc., a

Include this file within compat_netbsd/Makefile.common so that the
*EXEC_FMT variables (defined by the compat*/emulator.mk files) are
defined. This fixes the build of compat* packages.
XXX emulator-opsys.mk will go away in the near future as we do more
XXX appropriate information hiding.
pkgsrc/emulator/compat* and pkgsrc/emulator/netbsd32_compat* packages
to provide the necessary shared libraries to run dynamically linked
NetBSD binaries from the days of yore.
* Add some additional compat* packages for completeness:
compat15, compat20, compat30
* Modify the compat* packages so that "compatNM" only provides files
that aren't in "NetBSD-N.(M+1)". For example, compat12 only provides
files that don't exist in NetBSD-1.3.x, compat13 only provides files
that don't exist in NetBSD-1.4.x, etc.
As a result, if you are running NetBSD-3.0/alpha and want to run a
1.3 dynamically linked binary, there is an automatic dependency
chain that causes the following packages to be installed:
compat13, compat14, compat15, compat16, compat20
There are some deviations from this dependency chain on platforms
that have changed executable formats, e.g. i386, m68, sparc, etc.
However, in general pkgsrc will require that you have the necessary
COMPAT_* options in your kernel to match the installed compat*
packages. This restriction is an artificial one imposed by pkgsrc,
but allows for a single set of distfiles to be used on all versions
of NetBSD.
* Provide compat* package support for every supported architecture
of NetBSD. Verily, it is now possible to run 1.2 binaries on
NetBSD-1.5.3/pc532 by installing the compat12 package from pkgsrc.
Rejoice, one and all!
* The netbsd32_compat* packages mirror the corresponding compat*
packages for use by sparc64 and x86_64 to allow running 32-bit
binaries with COMPAT_NETBSD32 kernel support. The "extras" packages
supply the additional shared libraries from the corresponding release
of NetBSD so that the set of files in /emul/netbsd32 will be complete.
* pkgsrc/emulators/compat_netbsd contains infrastructure files shared
by all of the compat* packages.

* Fixed hangups on certain platforms after long gameplay of several games.
* Fixed several joystick bugs.
* Improved cdrom support. (fixes for audio, iso and detection.)
* Improved SVGA and VESA. (detection and display)
* Fixed a few textmodes and improved ansi emulation a bit.
* Fixed pcspeaker and certain types of soundeffects.
* Added undocumented mousebackdoor.
* Made mount and imgmount a bit easier to use. (ioctl by default, support
for ~ and ~username, auto size guessing for images)
* Fix a few compilation problems on various hosts and a general code
cleanup.
* Several small fixes that improve compatibility.
- Support for activation contexts and side-by-side assemblies.

creating the /emul/linux symlink on a system where /emul doesn't exist.
Problem noted by <wiz> in private email.
Bump the PKGREVISIONs of suse100_base and suse91_base (and also the
corresponding suse32 packages by implication).
_LINUX_MODULES was an old, internal name I used in my development of
the emulator framework that I had renamed to _EMUL_MODULES everywhere,
or so I had thought.
This should fix the problem where the dependencies on suse_* weren't
being converted into dependencies on suse32_* on x86_64 platforms when
building a "linux-i386" package.
current working directory. This should fix problems installing the
suse*_base and suse*_vmware packages as a privileged user.
When this package is installed as a privileged user, the +ROOT_ACTIONS
script is executed from ${WRKDIR}/.pkginstall before the package
metadata directory exists.
binary-only packages that require binary "emulation" on the native
operating system. Please see pkgsrc/mk/emulator/README for more
details.
* Teach the plist framework to automatically use any existing
PLIST.${EMUL_PLATFORM} as part of the default PLIST_SRC definition.
* Convert all of the binary-only packages in pkgsrc to use the
emulator framework. Most of them have been tested to install and
deinstall correctly. This involves the following cleanup actions:
* Remove use of custom PLIST code and use PLIST.${EMUL_PLATFORM}
more consistently.
* Simplify packages by using default INSTALL and DEINSTALL scripts
instead of custom INSTALL/DEINSTALL code.
* Remove "SUSE_COMPAT32" and "PKG_OPTIONS.suse" from pkgsrc.
Packages only need to state exactly which emulations they support,
and the framework handles any i386-on-x86_64 or sparc-on-sparc64
uses.
* Remove "USE_NATIVE_LINUX" from pkgsrc. The framework will
automatically detect when the package is installing on Linux.
Specific changes to packages include:
* Bump the PKGREVISIONs for all of the suse100* and suse91* packages
due to changes in the +INSTALL/+DEINSTALL scripts used in all
of the packages.
* Remove pkgsrc/emulators/suse_linux, which is unused by any
packages.
* cad/lc -- remove custom code to create the distinfo file for
all supported platforms; just use "emul-fetch" and "emul-distinfo"
instead.
* lang/Cg-compiler -- install the shared libraries under ${EMULDIR}
instead of ${PREFIX}/lib so that compiled programs will find
the shared libraries.
* mail/thunderbird-bin-nightly -- update to latest binary
distributions for supported platforms.
* multimedia/ns-flash -- update Linux version to 9.0.48 as the
older version is no longer available for interactive fetch.
* security/uvscan -- set LD_LIBRARY_PATH explicitly so that
it's not necessary to install library symlinks into
${EMULDIR}/usr/local/lib.
* www/firefox-bin-flash -- update Linux version to 9.0.48 as the
older version is no longer available for interactive fetch.
* new style of artifacting
* corrected PMG in bizarre ANTIC/GTIA modes
* added 128 KB SpartaDOS X cartridge type
* added support for QVGA landscape smartphones, added the virtual keyboard
* new command-line option "-win32keys" for keyboard layouts different from US
* MS-Win: run the emulator in a window ("-windowed" on the command line)
* middle button support for ST and Amiga mice in X11 and MS-Win targets
- A number of gdiplus functions.
- More complete pdh.dll implementation.
- Support for MSI remote calls.
- Messaging support in crypt32.dll.
- Lots of bug fixes.
The changes between release 0.4.5.1 and 0.4.6 include, among other things:
o) NetBSD/pmppc can now run in the emulator (with root-on-nfs), on
an emulated Artesyn PM/PPC board.
o) An instruction combination has been implemented for the idle loop
used by NetBSD/arm (cats, netwinder, and iq80321). In plain English,
this means that if the guest OS inside the emulator is not using
any CPU, the emulator should not use much CPU on the host either.
o) Some minor SuperH emulation speed improvements.
o) General code cleanup: Non-working (skeleton) emulation modes have
been removed, to make it easier to maintain the source code in
the long run, and many unused/legacy constructs have been removed.
- Many MSHTML improvements.
- Several improvements to the sound support.
- A number of Winsock fixes.
- Several new supported constructs in the IDL compiler.
- Many Direct3D threading fixes.
- Lots of bug fixes.

Mednafen is a portable, utilizing OpenGL and SDL, argument
(command-line)-driven multi-system emulator with many advanced
features. The Atari Lynx, GameBoy (Color), GameBoy Advance, NES,
PC Engine (TurboGrafx 16), SuperGrafx, Neo Geo Pocket (Color),
PC-FX, and WonderSwan (Color) are emulated. Mednafen has the
ability to remap hotkey functions and virtual system inputs to a
keyboard, a joystick, or both simultaneously. Save states are
supported, as is real-time game rewinding. Screen snapshots may be
taken at the press of a button, and are saved in the popular PNG
file format.
Due to the threaded model of emulation used in Mednafen, and
limitations of SDL, a joystick is preferred over a keyboard to play
games, as the joystick will have slightly less latency, although
the latency differences may not be perceptible to most people.
on irc.

The changes between release 0.4.5 and 0.4.5.1 include, among other things:
o) OpenBSD/landisk has now had its first release (4.1, 2007-05-01).
Landisk emulation is now stable enough to allow OpenBSD/landisk
to be installed onto a disk image, and run from it.
o) Finally found and fixed an old bug in the address to symbol name
lookup mechanism, which caused some symbols to be missed. Debug
output with -t or -i should now show all symbols.
- Midi support in the CoreAudio driver.
- Mixer support in the Alsa driver.
- A lot of MSI fixes.
- Implementation for most D3DRM functions.
- The usual assortment of Direct3D fixes.
- Lots of bug fixes.
by dsl@, with diagnostic by veego@. compat32.mk overwrites some vars
required to make suse work, but it wasn't overwritting those vars
for the fetch target.
I didn't see that error because I had the distfiles on my DISTDIR.
Support is added via the options framework, to use 32-bit packages
must be used "PKG_OPTIONS.suse=compat32", otherwise it will use
the 64-bit packages by default.
Known packages working are opera (does not require any change in Makefile)
and rar-bin.
Tested by some, closes PR pkg/35477 by Michai Chelaru (which provided
a patch more or less than this one).
