mame: update to 0.237.

For everyone who’s waited patiently all month, MAME 0.237 is out
today! As well as the updates to the UI and debugger that we’ve
already announced, there are several updates to the included plugins:

* A brand-new input macro plugin.
* The data plugin can now show text from the Japanese command.dat
  file (or a Chinese command.txt file if you rename it to command.dat).
* The location the hiscore support plugin uses to store its data
  and configuration has changed. You won’t lose your high scores,
  but you need to move the .hi files from the hi folder to the hiscore
  folder in your plugin data (homepath) folder.
* The configuration format for the autofire plugin has changed.
  Unfortunately, you will need to add your autofire button settings
  again.

Interesting machines added this month include a Mexican TRS-80
Color Computer clone, Tronica Thunder Ball (a re-skin of Space
Rescue with a nautical theme), the original version of Pengo that
the widespread bootlegs seem to be based on, the original hardware
revision of the Laser 128 (Apple II clone), and a slightly older
version of Street Fighter Zero 2 Alpha for Asia.

Master of multi-memory controllers kmg is still on a roll broadening
NES/Famicom and clone cartridge compatibility. Highlights of the
month include:

* Railway management simulator A Ressha de Ikou.
* Recent NES/Famicom games released by Ancient to promote Gotta
  Protectors (Minna de Mamotte Knight). NES development is still
  alive over two decades after the last licensed title was released
  in 1995.
* The two Korean Brilliant Com (영재컴) edutainment games.
* Some multi-game cartridges featuring the ambitious Titenic game,
  inspired by a highly successful James Cameron film.
* Kart Fighter – using the engine from an unlicensed NES port of
  Street Fighter II, and unlicensed depictions of the character roster
  from Super Mario Kart, this is almost a premonition of Super Smash
  Bros. It even features Yoshi’s tail smash, and depicts Kinopio
  (Toad) as a bare-knuckle brawler long before the Mii costume was
  available for purchase.
* Well-known low-effort Mario-themed hack 7 Grand Dad. PUSH ↑ START
  BUTTON. GET ADDITION GAME. AND NOURISH THE BLOOD

Amiga software compatibility has been improved this month, the NEC
PC-6001 family has gained a cartridge software list, and another
batch of Commodore 64 cassettes has been added. An issue was
identified with “fake E7” Apple II cracks that could prevent them
from working if they were written out to disks to use on original
hardware. Although this didn’t prevent them from being used in
MAME, disk images with the issue fixed have been added to the
software list. Over a hundred Apple IIgs cracks have been added,
too.

emulators: Remove SHA1 hashes for distfiles

Log message:
mame: update to 0.236.

The big event of the day is here! MAME 0.236 is ready for your
enjoyment! Sadly, this month marked the passing of Sir Clive
Sinclair, who it could be argued did more to put computers into
the hands of everyday people than anyone. There’s a small update
to MAME’s ZX Spectrum software list in this release.

The effort to dump and preserve protection microcontrollers is
still going well. This month’s additions include Juuouki and Wonder
Planet. Protection simulation has been removed for Wonder Planet
and Space Harrier. Remember, this is a worthy cause that provides
multiple benefits: it improves accuracy by taking guesses out of
emulation, helps people maintain and repair ageing arcade boards,
and simplifies MAME’s code.

MAME’s NEC PC-8001 now supports floppy disks. The PC-8001 and
PC-8801 software lists have been reorganised to match, and a big
batch of items from the Neo Kobe collection have been added. MAME
continues to improve its NES/Famicom cartridge coverage. There are
a whole lot of games you can play now, including Chinese RPGs,
fighting game bootlegs, and pirate multi-game cartridges. Experience
a parallel universe of software of such inconsistent quality that
you can’t stop going down the rabbit hole! Saturn emulation has
seen a few improvements, with several games that didn’t boot
previously reaching playable status this month.

As you might expect, the FM Towns, PC-98 and V.Smile software lists
have been updated as usual. A couple of recently dumped prototypes
have been added to the SNES and Game Boy software lists. The
SpongeBob SquarePants Jellyfish Dodge game has been dumped and
emulated, and a Korean version of Sotsugyo Shousho known as Jor-eop
Jeungmyeongseo has been found. More pleasant surprises include
working emulation for the IDE protection dongle included in Killer
Instinct 2 upgrade kit, and some fixes for Atari 8-bit home computers
using the ANTIC video chip.

For people with more exotic tastes, MAME has added its oldest
working software list additions: Munching Squares and Punchy for
the MIT TX-0. There’s also a new disassembler for the DEC VAX
architecture. In more mundane news, you can now reduce the
proliferation of duplicate ROM sets for families of similar keyboards
and other devices.

Log message:
mame: update to 0.234.

Hi everyone! After four busy weeks, MAME 0.234 is ready! Newly
supported systems include Runaway (a licensed version of Sega’s
Head On made by Sun Electronics), Konami’s Magical Twin Bee (the
European version of Twin Bee Yahhoo!), and Tronica’s LCD hand-held
Spider (same program as Space Mission, but with different artwork).
Although it was added last month, VS Mahjong Triangle is now working.
This is a rare early example of a mahjong game supporting two
simultaneous single-player games, or a two-player game – a format
popularised a decade later by Psikyo’s Taisen Hot Gimmick.

There have been two significant sets of improvements for 3D arcade
games this month: rewritten 3dfx Voodoo Graphics emulation, giving
significant performance gains in many cases, and continued development
on Konami’s ZR017 and GTI Club hardware. Although not directly
related to 3D graphics, bug fixes for the Fujitsu TGP DSP make
Motor Raid more playable. We haven’t forgotten 2D arcade games –
Namco racing games have seen another round of fixes for missing or
incorrectly positioned sprites, and missing sprites are now drawn
in Data East’s Chanbara.

For home systems, our friend kmg has been hard at work adding
support for pirate NES/Famicom cartridges, and Brian Johnson has
fixed a couple of video issues on the Epson QX-10. Kelvin Sherlock
added support for the LANceGS card, providing another networking
option for Apple II users.

Log message:
mame: update to 0.233.

Are you ready for MAME 0.233? With dozens of reported issues fixed,
over a hundred pull requests merged, and a flurry of development
across all areas, our mid-year release is huge! Some of the more
interesting machines added this month include several prototype
JAKKS Pacific TV Games, the elusive English version of Namco’s
Armadillo Racing, and the LCD hand-held game Space Mission from
Tronica.

There are lots of new Apple IIgs and Macintosh software list items,
tying in nicely with the recently improved emulation of these
systems, as well as an update to the Colour Genie collection, and
a massive haul of MicroBee floppy dumps. A few more Mattel Juice
Box cartridges have been dumped, allowing you to marvel at the
poor-quality, 6 frames-per-second video.

Significantly improved systems include the Atari Portfolio, Tandy
MC-10, and Tandy VIS. Carl has continued to work on Japanese home
computers, and Ville Linde is back this month, bringing a batch of
updates for the Konami Hornet platform. Juno First, The Tin Star,
The Empire Strikes Back have all had bugs squashed, and some of
the last remaining regressions from the Yamaha FM synthesis rewrite
have been resolved. David Haywood has turned his attention to
bootlegs of games including Final Lap 3, Guttang Gottong, and Alien
Storm.

This release includes preliminary sound support for the Super A'Can
console. On the topic of sound, some Yamaha synthesisers have been
promoted to working, and MAME can now play back standard MIDI files
to exercise machines that take MIDI input.

There are several general usability improvements in this release,
including updated Chinese and Greek translations, better configuration
handling for slot devices, and a few small enhancements to the
built-in user interface. Issues with artwork using SVG and Windows
DIB (BMP) images on ARM/AArch64-based Linux systems should also be
fixed.

Log message:
mame: update to 0.232.

It’s time for MAME 0.232, and do we have a surprise for you! The
incredibly rare Universal game Mrs. Dynamite has finally been found
and dumped! This is an early example of a game where you place
bombs to kill enemies that walk over them, showing Universal’s
flair for cute characters and cutscenes. Mrs. Dynamite is believed
to had performed poorly on location tests, and never had a widespread
release. The graphics in the version that has been dumped don’t
match what’s shown on flyers. Other arcade additions include Dokaben
2 and a prototype of Spinal Breakers.

Namco racing games have taken a leap forward this month. Final Lap
has its sprite chip hooked up subtly differently to later games on
the System II platform, which had been causing graphical issues on
the title screen. Lack of playback status register emulation in
the C140 sound chip was causing issues with engine sounds in Final
Lap, Suzuka 8 Hours, and Four Trax. The horizontal position of the
road layer has also been adjusted to better match videos made using
original hardware.

A number of bug fixes allow previously unplayable Japanese home
computer games, including µPD7220 issues affecting the Madou
Monogatari games on PC-98, the missing 1-bit DAC sound on PC-98,
broken sprites in Asuka 120% Burning Fest. on FM Towns, and background
bugs on Sharp X68000. Mac media support continues to improve, with
working CD-ROM drives on more Macs, and fixes for high density
floppy drives. The V.Smile Smart Keyboard is now supported, in US,
French, and German variants. Tim Lindner has continued to fix
long-standing bugs in Tandy CoCo 3 emulation.

Software list additions include Taiwanese Game Gear cartridges,
Master System prototypes, a big batch of software for the Australian
MicroBee series, and quite a few add-on ROMs for the Acorn BBC
Micro. We’ve also got the latest Apple II floppy dumps and cracks,
FM Towns floppies and CDs, and PC floppies.

Log message:
mame: update to 0.231.

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.
