MAME 0.231, our April release, is out now! The Yamaha FM synthesis
rewrite is progressing, with the OPL family (including YM2413,
YM3526, YM3812, YMF262 and Y8950) done this month. A number of
regressions reported against the previous release have also been
fixed. Most things should be improved, but if you notice something
wrong with a system using one of these chips, be sure to let us
know. Warp-1, a very rare Sun Electronics game from the late ’70s,
has been added this month. This is an early example of an “into
the screen” space shooter.
For as long as it has been emulated, the “3D” stages in Contra have
been too easy. This comes down to the functionality of the Konami
007452 chip, which Konami calls a VRC&DMP. Now we know that VRC
stands for Virtual ROM Controller, and controls ROM banking. However,
the DMP part has been more of a mystery, assumed to be some kind
of protection. This month, furrtek worked out that it’s apparently
some kind of Divide/Multiply Processor, for 16-bit maths operations
that would be unacceptably slow on the games’s pair of 6809-family
CPUs. The great news is the game now runs correctly, the bad news
is you’ll probably die a lot more.
David “Haze” Haywood is back this month with fixes for several
arcade games that have never been quite right. He’s fixed graphical
priority issues in SNK’s Beast Busters and Mechanized Attack,
improved timing in Seibu Kaihatsu’s Shot Rider, and corrected layer
offsets in Mitchell’s Funky Jet. He also added support for a couple
of protected Mega Drive bootleg games from Argentina. Recently,
David has been streaming MAME gaming sessions, often highlighting
under-appreciated games. You can watch the recorded streams on his
YouTube channel. Still on the topic of things that have never been
right, sasuke has been busy this month. He’s improved the Nichibutsu
1412M2 DAC playback rate and timer period calculation, most noticeable
on the Mighty Guy soundtrack, and made Taito’s unicycling game
Cycle Maabou playable.

Switch & 3DS Audio Support
Overview
Good news: This release focuses on enabling the new music from the Nintendo
3DS and Nintendo Switch version to be used. This audio is in native format,
rather than streamed. Yey.
Bad news: It is incredibly complex to extract the audio. And I cannot provide
it for legal reasons. Boo.
I have provided a wiki page which provides a rough overview of what's
involved. I'll add instructions for the 3DS release at a later date.
Please replace your old config.xml file when upgrading to this release.
What's New
* [Audio] Nintendo Switch and Nintendo 3DS Audio File Support.
* [Audio] Sample Rate can now be set in config.xml. Default frequency
increased to 48Khz, which makes a difference for FM generated audio.
* [Audio] Music Test menu now supports additional audio files
* [Audio] Extra music tracks no longer replace existing audio.
* [Audio] Music selection screen auto-adjusts when new audio added with
new scrolling format.
* [Bug] Fixed long-standing bug where there was a 50% chance of a blank
screen when switching from 60fps to 30fps mode.
* [Techy] MML format better documented in osound.cpp source code.
Additional command added to support Step On Beat.
most of these simply extend matching from "aarch64" to "aarch64eb"
in various forms of code. most remaining uses in pkgsrc of
"MACHINE_ARCH == aarch64" are because of missing aarch64eb support,
such as most of the binary-bootstrap requiring languages like rust,
go, and java.
no pkg-bump because this shouldn't change packages on systems that
could already build all of these.
ChangeLog:
20210228 Switching back from C++ to plain C.
Implementing a helper method for registering device addresses
as symbols (so that it can be used from several machines).
20210307 Subtle colorized output when stdin/stdout are connected to a
tty, to make it quicker to interpret text output. Enabled with
-G or by setting the CLICOLOR environment variable. Can be
disabled with -A.
20210309 Beginning to separate debug messages into subsystems, that have
individual verbosity levels.
Making -K work more consistently (enter the debugger at the
end of a run). -V implies -K.
Making -T work better for M88K (breaking into the debugger
directly on bad memory accesses, if -K is used).
20210310 All MIPS machines now register their devices as symbols (based
in kseg1, i.e. 0xffffffffa0000000).
20210311 Making -T work better for MIPS, PPC, ARM, and SuperH.
20210314 Adding a -L command line option for enabling tap networking
without using configuration files.
-x is now needed if one wants separate xterm windows for serial
I/O when using configuration files with a single machine.
20210316 debugmsg subsystems can now be registered at runtime; this is
so far done from the Lance Ethernet device.
Adding a 'verbosity' debugger command for inspecting and
setting the verbosity level for individual subsystems.
20210318 Fixing an annoying 'backspace' bug in the debugger command
line handling, where the response sometimes could become
"unknown command ''".
Implementing CTRL-W (erase word) in the debugger.
Implementing CTRL-T (SIGINFO-like status line) in the debugger.
20210320 Removing the UNSTABLE_DEVEL configure define; it was not used
much, and the debugmsg verbosity levels can be used in its
place.
Fixing a bug for MIPS R2000/R3000 when writing to coprocessor 0
"entrylo" register (if the lowest 8 bits were 0, the code took
the non-R2000/R3000 code path).
20210321 Adding an empty i960 CPU skeleton [again].
Moving 'arch' from struct machine to struct cpu; in the future,
perhaps this would allow a machine to have heterogenous CPU
sets (such as the Dreamcast with both SuperH and ARM).
Removing "slow_serial_interrupts_hack_for_linux" (-U) command
line option, since it is not used for most guest OSes, and
occupied a command line option char.
20210323 Breaking out the mb89352 SCSI Protocol Controller from the
luna88k device, and beginning to implement it. Works well
enough for OpenBSD's "boot" to read the disk and load the
kernel, but not well enough for the kernel to like it.
20210324 Adding support for 00 99 01 07 variant of luna88k a.out.
20210325 The mb89352 SCSI controller uses its own subsystem for debug
messages.
20210327 Adding an empty RISC-V CPU skeleton [again].
Implementing enough of the mb89352 to allow OpenBSD/luna88k
to boot with SCSI (both the boot loader and the kernel)!
20210401 Applying a patch from George Matsumura to make things build
better on Linux: __attribute__((__packed__)); in bootblock.h.
20210405 Adding hardcoded boot_unit=0 and boot_partition=0 NVRAM
variables to the LUNA-88K machine, allowing OpenBSD/luna88k
to boot from disk without asking for root and swap partitions.
Adding 'R' (upper-case) disk image prefix, as a shorthand for
creating temporary overlays.
20210407 Code for idling the host processor has been moved out from
individual CPU implementations to the main emul loop.
Implementing an X11 mouse pointer grab mechanism. Grab is
activated by clicking in a framebuffer window, and released
using left CTRL + ALT. When grab is active, the host mouse
cursor is hidden and the window caption changes to indicate
that grab is active.
20210408 Implementing an unusual 88K "not_maxneg_nor_zero" bcnd
condition.
20210409 Moving the LUNA88K framebuffer to its own device file.
Beginning to implement the LUNA88K front panel LCD.
Also fixing a bug where the rightmost pixel (or 8 pixels in
the case of monochrome) were not drawn.
20210410 Also check for X11R7 in the configure script, in addition
to X11R6.
20210417 Porting over i960CA disassembly from the C++ framework.
20210418 More i960 stuff, including re-adding the (so far dummy)
Cyclone VH machine.
Assuming availabilty of __func__ (C99 standard).
20210422 Enabling idle detection for OpenBSD/luna88k, which uses a
bcnd.n instruction. A hack, but it seems to work.
Fixing a bug where console input could randomly be lost when
idling, if there were multiple emulated serial ports.
6.5.2 to 6.5.3 (April 20, 2021)
* Added context-sensitive help.
* Improved support of multiple monitors with different resolutions.
* Improved analog input reading (Paddles, Keyboards...).
* Fixed QuadTari support for controller types other than Joysticks.
* Fixed palette and TV effects saving for Retron77.
* Fixed immediate disassembling when switching options in debugger.
-Have fun!
Changelog:
20210215 Implementing the fadd.dss 88K instruction, and working a bit
more on the exception cases in the xmem instruction.
20210220 Implementing mouse emulation support for the LUNA88K machine.
Updating OpenBSD/sgi install instructions (6.5 -> 6.8),
and including a screenshot of X11 running.
20210221 Handle return values from interrupted select() when checking
for available console input. (Found when using CTRL-C on Linux
to enter the debugger command line, and noticed that it was
spuriously broken.)
20210222 Basic multiprocessor bootup of OpenBSD/luna88k now works, but
it is slightly unstable.
Fasten your seatbelts and get ready for MAME 0.230! There are big
changes this month, but before we get to that, let’s highlight some
of the more routine additions. Several TV games featuring adaptations
of popular Hasbro board games are now supported, as well as a couple
of VTech systems featuring Dora the Explorer. Several electronic
toys and handheld LED game from Mattel and Invicta have been emulated
this month. There’s a big update for the Apple II software lists
this month, with clean cracks of lots of educational software from
MECC.
If you’ve been following along with development, you’re no doubt
excited about the new Yamaha OPM/OPN (YM2151, YM2203, YM2608,
YM2610, YM2610B, YM2612, and YM3438) sound emulation core. This
addresses numerous subtle and not-so-subtle issues, particularly
in Sega and Data East games. Windy Fairy and Jennifer Taylor have
continued to improve MAME’s support for Konami rhythm games, making
beatmania IIDX, Beatmania III, Keyboardmania and ParaParaParadise
games playable. Thanks to Happy, a couple more graphics issues with
the Hyper Neo Geo 64 have been fixed.
There’s been a lot of work on the Apple IIgs and 68k Mac drivers
this month. As well as the flood of machines promoted to working,
Apple 3.5" floppy support has been revolutionised, and improvements
to ADB GLU microcontroller simulation make the IIgs control panel
usable. On the console side, save EEPROM support has been fixed
for several Mega Drive games.
Changes since 0.31:
Controller Improvements & Rumble Support
This release focuses on Controller Support & Improvements.
Please replace your old config.xml file when upgrading to this release.
* [Controllers] Basic rumble support can now be enabled from the CONTROLS
menu. The strength can be adjusted. The code that controls the rumble is
identical to that of the upright arcade machine motor shaker. The option
will only show in the menu if your controller is supported.
* [Controllers] Auto-detection and assignment of controller buttons and axis
should be much improved. I will update the manual to call out the default
controls in due course. (Right trigger = accelerate, Left trigger = brake,
Start = Start, Back = Menu, A = Gear Change, X = Change View, Y = Coin).
These can be redefined as desired.
* [Controllers] D-Pad can be used in menus.
* [Menus] Gamepad/Joystick settings has its own menu.
* [Menus] Ensure that 'A' button on controllers can be used to select items.
Analog accelerate is now only used when run via original arcade cabs as
it's not optimal.
* [Rom Loader] Sped up CRC32 based loading by using a Hashmap. It was
reportedly slow when used over a network.
* [Rom Loader] It is possible to switch back to the old filename loading
system via a setting in config.xml
* [Config] It is now possible to change and configure the location of the
'res' directory.

Changes since 0.3.2019102:
Maintenance Release
This release focuses on upgrading the libraries and compilation tools CannonBall
uses, as I hadn't maintained the codebase in a number of years. Most of these
changes will be invisible to most users. Right now, I'm trying to get the house
in order as opposed to add lots of wild new features! :)
* [audio] Audio updates at the correct rate and resolves the longstanding
issue with music and sound being very slightly 'off'
* [roms] ROMs are now read by CRC 32 value. Filenames no longer matter - so
long as they are present they can be renamed to anything.
* [roms] Fixed expected Z80 rom file length
* [controls] Start Button behaviour less 'sticky' and buggy
* [controls] Analog axis for accelerate and brake can now be configured via
the in-built menu system
* [menu] Reduced delay when scrolling through menu with analog controls
* [config] ROMs and save data can be relocated to separate locations
* [bug fix] Time Trial mode no longer crashes if used as the first mode played
* [timing] Code tries to use V-Sync for timing OR internal timing, as opposed
to both at once
* [source] SDL 2 used by default. SDL 1 removed from codebase. This appears to
have fixed compatibility bugs for some people
* [source] Added compatibility for upcoming SmartyPi hardware (Pi 4 based) to
run on original arcade hardware
* [source] A general clean-up in many areas
would select the nvmm library when it wasn't disabled that later was not
found.
While here, also fix a curses issue introduced in version 5.2.0nb2; it would
not find the appropriate library.
