just use it in place of the hand-rolled script.
Linux compatibility package based on the openSUSE Linux distribution.
Please visit http://www.opensuse.org/ for more information about openSUSE
Linux.
This package supports running ELF binaries linked with glibc2 that
require GTK+-3.x shared libraries.
You know what time it is? It’s time for MAME 0.238, our November
release! After many years of waiting, the rare space shooter Monster
Zero from Nihon Game is now playable. Despite the title, this game
does not feature a three-headed space dragon. This release adds
support for Fowling and Monkey Goalkeeper, two more Elektronika
hand-held games built around the Egg/Mickey Mouse Game & Watch
program.
There are a few changes to MAME’s UI and the debugger this month.
Firstly, MAME is now less eager to reset your input configuration
if you run it without connecting a game controller. Analog inputs
support a few more configuration options, and we’ve added some
(long overdue) documentation for the input configuration process.
The timecode logging feature (used by people making gameplay videos)
has been moved to a plugin, and debugger memory views now support
octal data display, and octal or decimal address display.
Support for several Famicom controllers has been added or fixed
this month, including the IGS Tap-tap Mat, Bandai Family Trainer,
Bandai Power Pad, Bandai Hyper Shot, Konami Doremikko Piano Keyboard,
and Konami Exciting Boxing air bag. Also involving peripheral
support, the Acorn Archimedes drivers now support podule expansions,
the Econet module slot, serial/parallel ports, and extension ROM
sockets.
- added proper support for Clang to the makefiles (by dbjh)
Indicate that you want to use Clang by setting the environment variable CC.
Either at configuration time:
$ CC=clang ./configure
Or at build time:
$ CC=clang make
- updated (SNES) implemented dumping for --xgd6. 15 years late, but still the
only tool to do it :-) (by dbjh; thanks to Kristian Gunstone for making me
try to explain why it could not be done ;-) )
- restored support for NetBSD/i386 and OpenBSD/i386 in makefile of libcd64 (by
dbjh)
- updated FAQ with explanation about how to compile uCON64 on macOS with support
for USB (by dbjh)
- fixed some issues in MinGW, MinGW-w64 and Visual C++ ports that made them
choke on files larger than 2 GB. On 32-bit UNIX try adding
-D_FILE_OFFSET_BITS=64 to CFLAGS to fix the issues (by dbjh; thanks to
Mystic_Merlin for testing on Windows 98)
- updated (all) upgraded unzip to version 1.1 (by dbjh)
- updated (SNES) --gd3 writes correct SRAM mapping values for Trials of Mana
(by dbjh; thanks to Mystic_Merlin for reporting the issue and testing)
- updated (SNES) --gd3 supports 64 Mbit HiROM games. It works at least for the
English fan translation of Fire Emblem - Seisen no Keifu (J) (Project Naga,
beta version 7) (by dbjh)
- updated (SNES) --gd3 supports up to 64 Mbit LoROM games. It works at least for
the 48 Mbit English fan translation of Fire Emblem - Thraki 776 (J) (V.ROM)
(Lil' Manster 1.07) (by dbjh)
- updated (all) --hfind and --hfindr accept search strings without spaces (by
dbjh; thanks to eadmaster for the feedback)
- renamed (all) --dual to --bit (by dbjh)
- updated (all) --hex, --bit, --code and --print accept an optional end offset
(by dbjh)
- added (all) --hreplace=S:R find S and copy R to the start of each match
(wildcard: '?') (by dbjh; thanks to eadmaster for the suggestion)

No revbump needed since the change is limited to Darwin, where no built
package previously existed (at least for Darwin 20.6.0 which I tested).
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.
Since there are no simh releases there are also no release notes to summarize.
The previous snapshot was over 3 years ago: 2018-09-19.
A somewhat controversial change with some people is that simh now
appends a "footer" block to disk image files, containing metadata
(struct simh_disk_footer). ATTACH -r <disk_unit> <filename> will avoid
this but makes the device read-only.
New information from the README.md file:
DO <stdin> Invokes a nested DO command with input from the
running console.
RUNLIMIT Bound simulator execution time
TAR Manipulate file archives
CURL Access URLs from the web
Changes in the built emulator models:
- several new VAX models (vax8200, vaxstation{3100,4000}*, infoserver*)
- several new PDP-10 models (pdp10-{ka,ki,kl})
- new: pdp6
- Intel-Systems: Merge MDS, SDK, OEM simulators into Intel-MDS simulator
The files ka655x.bin and vmb.exe are no longer installed since they are
not required for operation (they are built into the VAX models that use
them), and it is strange to single out these ROM images out of over 30 to
install. LOAD -r can load alternative versions.
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.
