-------------------------------------------------------------------------
Changes in 1.4.1 (June 22, 2002):
- now cdrom is enabled in configure, unless you specifically disable
it with --disable-cdrom. (Christophe)
- fix compile error in main.cc when SMP or APIC is enabled (Dave)
- the runtime menu now displays 11 (continue) by default (Bryce)
- initialize DMA controller before floppy and SB16
- fix DMA panic when installing win95 (Volker)
- first character of the vga bitmap is blank on win32 (Volker)
Before, it was incorrectly coded as a '@'.
- AltGr key on European keyboards works now on win32 (Volker)
- fix problem with console/serial port on Bochs exit (Volker)
- enable serial port for GNU and GNU/Linux (Volker)
- small documentation fixes (Volker)
- remove unnecessary include statements for X11 (Volker)
- italian keymap added (Emanuele Goldoni)
- fix win32 ethernet frames error. It will no longer reject packets
that are less than 60 bytes long. (Peter Tattam)
- BIOS fixes :
- win2k cd-boot (Christophe)
- emm386 crash (Dave)
- cs=0 at boot time (Christophe)
- keyboard failure in scandisk (Dave)
- fix bug in forming the 64-bit APIC base address from two 32-bit registers.
A compiler warning in cpu/proc_ctrl.cc pointed this out.
- fix default choice in the runtime options menu
Changes since snes9x-1.37.3 include:
- Fixed a timing problem caused by a speed up hack that was affecting Top Gear
3000. No the game still isn't playable, but I noticed the problem while
investigating the DSP-4 chip used by the game.
- Added support for Star Ocean and Street Fighter 2 Alpha decompressed graphics
packs from dejap. Used a binary chop search rather than a linear search to
locate correct decompressed graphics more quickly - should help emulation
speed during later stages of the game.
- Included the latest ZSNES DSP-1 code. Now Pilotwings, SD Racer and Suzuka 8
Hours are playable. Aim For The Ace, Super Air Diver 1 & 2 and Syutoko
Battle 94 are also playable, but with bugs. Thanks to zsKnight, _demo_, et
al for all their hard work.
- Another Daffy Duck: Marvin Missions screen flicker problem worked around -
writing to the IRQ enable register shouldn't clear any pending IRQs, but
Sieken 3 seems to require this or else the game hangs. Special-cased Daffy
Duck for now.
- An NMI emulation bug was triggering a Panic Bomberman World game bug,
crashing it. Basically, if a game enables NMIs after the normal trigger
point, the NMI should not trigger if the game has already read the NMI clear
register.
- Panic Bomberman World requires SPC700 memory to be initialised to zero on
reset otherwise the game hangs when a tune finishes and another one should
start.
- Added an offset hack for Strike Gunner to get the scrolling ground layer
to line up correctly - another offset-per-tile bug hacked around for now.
- Hmm. The broken cut-scenes in Deep Space 9 seem to indicate that I haven't
got the emulated clock speed of the 65c816 CPU correct yet. And not by a
little bit - a 9% too slow error. Hacked special timing for the game for now.
- Fixed another crash bug in the interpolated mode 7 code - if no scaling
was being used (either up or down) and screen repeat was enabled and the
screen was flipped horizontally, the routine would crash Snes9x. Was causing
Snes9x to crash during rock monster boss stage of Castlevania 4.
- Oops. Got the initialisation of the default SNES screen width and height
round the wrong way - could cause a X Windows System error message on the
UNIX port after loading a ZSNES freeze file.
The package has been changed to use the oss sound instead of the sun
sound driver. This improves the sound quality.
Remove `-p' from mkdir arguments, it is already part of ${MKDIR}.
While here substitute a couple of ${PREFIX} by `%D' in
`@exec ${MKDIR} ...' lines and add a couple of missing `%D' in such lines too!

P11 is a PDP11 emulator, which currently emulates the following configuration:
- a KDJ11A processor (including fpp)
- one or more RL-controllers (RLV12) with up to 4 RL02 each
- one or more RHV?? controllers with up to 8 RP06 each
- an RK11-controller with 22-bit addressing (hey ever saw one?)
- a MRV12 option (boot-rom/maintenance and display register)
- one or more KL11A controllers with up to 4 serial lines each
- a standard printer interface
- a read only TM11 tape
- a DEQNA ethernet adapter
- a toy clock
On a 900MHz Athlon under FreeBSD 5.0 a 'make build; make installsrc' of
2.11BSD takes around 2:24 hours - this is several times faster than
a real KDJ11A (if /usr is mounted async,noaccesstime).
Floating point speed is in the order of 10 times the original.
P11 successfully runs RSX11M-PLUS, UN*X Version 5/6/7, 2.11BSD, RT-4 and XXDP.
With thanks to David Talmage for the nudge.
It can boot a Norton Utilities CD, but not run any of the
utilities. That may be the known problem with the Windows 98 CD.
- - Add the ability, on NetBSD, to spin up the CD-ROM. This keeps
"disklabel cd0" while booted from the NetBSD 1.5.3 rescue floppy
from panicing the emulation, but it still doesn't return a label.
- - Go ahead and enable the network driver and dummy sound driver.
The network driver almost works under the NetBSD rescue floppy
(ifconfig works, but not ping). I have no way, currently, of
verifying the (dummy, silent) sound driver.
- - Bump to 1.4nb1.
of the more visible ones.
- ROM BIOS
- Christophe Bothamy added ability to boot from El Torito CDROM.
- VGA
- vga memory read/write functions in text mode fixed
- implementation of CGA mode 320*200*4 (patch from Sebastien Bechet)
- GUI changes
- cdrom button: click this to notify Bochs when you changed the CDROM (Volker)
- snapshot button: saves the text on the Bochs screen into a file called
snapshot.txt (Volker)
- copy button: on Win32 and X windows, copy the text on the Bochs screen
to the clipboard (Volker)
- paste button: on Win32 and X windows, paste the characters on the
clipboard into the Bochs window. This requires keyboard_mapping to
be enabled. (Bryce Denney)
- keyboard
- added an optional keyboard_mapping option that enables to use your
country specific keyboard with Bochs. If enabled, the keymap file must be
specified in bochsrc. The available keymaps are US, German, Spanish and
French for PCs running X11. Contributions are welcomed. (Christophe
Bothamy)
- added Windows(tm) key definitions (Volker Ruppert)
- added paste button, which causes the emulated keyboard to type characters
from the system clipboard. This only works when keyboard_mapping is
enabled. (Bryce Denney)
Generator is an open source emulator designed to emulate the Sega
Genesis / Mega Drive console, a popular games machine produced in the
early 1990s. It is a portable program written in C and has been
ported to the Amiga, Macintosh, Windows and even pocket PCs such as
the iPAQ and Cassiopeia. Natively it compiles under unix for X
Windows with either tcl/tk or gtk/SDL, for svgalib and even
cross-compiles to DOS with djgpp/allegro.
Generator uses its own custom 68000 processor emulation which is
designed for dynamic recompilation, and uses techniques from this such
as block-marking, flag calculation removal, operand pre-calculation,
endian pre-conversion etc. There are approximately 1600 C routines
generated by the first stage of compilation to cope with the 67
instruction families. These routines are used as a 'backup' when
dynamic recompilation isn't supported on your platform or the
recompiler doesn't support a particular instruction. The CPU engine
is by all accounts very fast, whatever the mode.
There is a 'test' recompiler written for the ARM processor, but it is
no longer supported. If someone with assembler knowledge wants to put
the effort into writing a recompiling back-end for a processor (and it
really is major effort), let me know - particularly if you know i386.
Changes since xmame-0.59.2 include:
- Everything from MAME 0.60, except for the new special controllers support.

- Updated the description of the new '-ctrlr' option in changes.mame

- Updated the V60 core to handle unaligned memory accesses, which
should fix some SSV games. (Nicola Salmoria)
- Updated 8080bw to fix the dip switches for Ozma Wars and its clones,

(Nephrite, Zsolt Vasvari)
- Updated drivers/psikyosh.c and vidhrdw/psikyosh.c to allow Lode

- Modified sound/ay8910.c to fix sound in some M62 games. (Nicola Salmoria)
- Updated drivers/wecleman.c to make the car in wecleman controllable.
(David Haywood)

so that the creation of the bulk build cache files works correctly on non-i386
machines. This speeds up the marking of all compat_linux packages as not available.
This change has no effect on i386.
