Are you all ready for MAME 0.263? This release has some big changes
that are going to affect everyone: several default UI control
assignments have changed, including pause and save/load state. The
changes will hopefully make life easier for people emulating
computers. After updating, please check the User Interface input
assignments and make any changes necessary for your setup.
We’ve fixed some long-standing bugs this month. Issues affecting
large hard disk images (tens of gigabytes) have been fixed, and
chdman will now report more invalid combinations of options rather
than just producing invalid output files. Crashes or hangs when
emulating systems that use discrete sound circuitry simulation on
multi-core ARM systems should be fixed, as well as occasional bad
sound output from the discrete circuitry simulation.
Thanks to recent work reverse-engineering the K052591 chip, this
release features improved protection simulation for Hexion, S.P.Y.
and Thunder Cross. Newly supported systems include a few computers
from the former Yugoslavia, two more Tiger LCD games, and several
more chess computers. The ROMs for the unreleased Deluxe Color
Computer have been dumped recently, allowing emulation to be
completed, and there’s a big update for the Apple II software lists
this month.

Changelog:
Brief summary of changes in 2.7:
- Bugfixes for CPU emulation correctness (CPUID/VMX/SVM fixes to support
Windows Hyper-V as guest in Bochs)
- Improvements for the plugin handling to simplify Bochs extensions
- Added "multiple NICs" support to the NE2000 and E1000 devices
- Added experimental FTP service for networking modules 'vnet' and 'socket'
- Fixes and improvements for all supported Voodoo graphics adapters
- Added USB keyboard emulation with most of the keys supported
- GUI "cmdmode": create a headerbar event with key combo starting with F7
- LGPL'd VGABIOS updated to version 0.8a (new VGABIOS for Voodoo Banshee)
After two long months, we’re back with MAME 0.262! Of course, it’s
full of exciting work on multiple fronts. In core media support,
MAME now supports FLAC compression for compact cassette images,
and Zstandard compression in zip archives and CHD disk images. For
maximum compatibility, chdman won’t use Zstandard compression by
default, so you’ll need to enable it if you want to use it when
creating or converting disk images. For your convenience, unidasm
now allows you to specify offsets in hexadecimal or octal.
Three LaserDisc games designed by Rick Dyer are now working: the
Japanese version of Time Traveler, the console-to-arcade conversion
Thayer’s Quest, and Don Bluth’s Dragon’s Lair. It’s very exciting
to see multiple LaserDisc captures combined to eliminate all dropouts
from disc degradation and pressing faults for Dragon’s Lair and
Thayer’s Quest.
Following up on work in the previous release, MAME now supports
Sega’s TV Ocha-Ken system, based on the same technology as the
Advanced Pico BEENA. It’s a far simpler system designed for young
children, using barcode cards to trigger mini-games. Also from
Sega, initial support for the AI computer has been added. No, this
isn’t related to the current artificial intelligence craze; it’s
a rather obscure system from 1986 featuring a pen tablet and using
cartridge and compact cassette media.
Two more Casio Phase Distortion synthesisers have been added: the
CZ-230S keyboard and the rare SZ-1 sequencer. The CZ-2230S lacked
sound editing features but added a programmable drum machine (using
PCM samples) and sequencer. Also in synthesiser emulation, MAME’s
Wave Blaster host driver now supports multiple synthesiser modules
from Casio, Samsung, and Yamaha. In other musical news, the original
version of the very obscure Shamisen Brothers rhythm game from
Kato’s has now been fully dumped and emulated.
The microcontroller program for Taito’s KiKi KaiKai was recently
extracted. This contains a substantial amount of game logic, allowing
the simulation code previously used by MAME to be retired and giving
more confidence that the emulation is accurate. Improvements to
our Fujitsu MB8841 emulation have fixed persistent issues in Arabian
from Sun Electronics. HT1130 microcontrollers are now supported,
allowing cheap hand-held “brick games” to be emulated, albeit
without sound for now.
This is a big release for chess computer emulation. There are lots
of newly supported chess computers from the brands you love, like
Hegener + Glaser, Novag, and Saitek, as well as more versions of
systems that were already supported. There were also a couple of
backgammon computers added, from Saitek and Tryom.
There’s inevitably far more than we have time to talk about here,
including an Arabic version of the Mattel Aquarius, an 8" floppy
drive controller for the Apple II family, numerous Aristocrat
Leisure gambling systems promoted to working, some big software
list updates, and lots of code modernised.
This checks if MAP_FIXED_NOREPLACE is available in libc headers and only
enables linux-user targets if there, avoiding inevitable build failure.
This is relevant for CentOS 7.9, ubuntu 18. May be phased out in some years,
I presume, or once the main qemu targets also stop working.
Version 5.2.0 (2023/12/29)
New features:
possibility of renaming the host device "letter" from previously hardcoded
H: to any letter but C: (cassette), E:, K: and S:
So if you have e.g. a program with hardcoded "D:" (as for diskette) you
can now use it on a host device as well by renaming the host device to D:
either via the Emulation configuration -> Host device settings menu
or using command line option
-Hdevicename <X>
little thing but useful (for me at least): tooltip in the settings
menu that reminds users there are virtual host devices with
automatic ATASCII<->ASCII conversion (mainly end-of-line character).
Extremely useful for all text files including ATARI BASIC source code
that can be stored using LIST "H6:PROGRAM.LST" and read back using
ENTER "H6:PROGRAM.LST" (H6 = H1 with ASCII conversion, etc.).
Version 5.1.0 (2023/12/28) - released at SILK
Thanks to all the contributors (see git log for each commit author)
New features:
New command line options:
-playbacknoexit => don't exit the emulator after playback finishes
-joy-distinct => allows larger number of joysticks by not combining multiple physical
devices into a single emulated joystick. For example this allows using
keyboard to emulate one or two joysticks, and to use these in conjunction
with physical SDL joysticks / controllers in order to play with more people
than there are SDL joysticks. The same logic gets applied to LPT joysticks,
these come after joysticks from keyboard emulation.
Furthermore, the logic also gets applied to put SDL joysticks after LPT
joystics even when the command line flag isn't set. Since LPT joysticks
take precedence over SDL joysticks on the same emulated device, this takes
a device that was completely ignored before and makes it useful now.
The assignments are fixed at program start-up, after config file and command
line flags have been taken into account. If the UI is used to enable or
disable a keyboard-emulated joystick, this can cause an emulated joystick
to be controlled by multiple physical devices, or by none.
Swap also SDL joysticks on AltL+J
This swaps all physical devices connected to the first two emulated
joysticks: the keyboard keys, the SDL devices, and the LPT devices.
After the swap the real joystick / hat setting in the UI will appear swapped
as well, but the keyboard setting won't.
Show all input events on a single line during recording
This way the recording file alternates between two forms of lines: input
lines which contain all keyboard and joystick events in one line, and output
lines with the screen content digest. By filtering out the former, the
latter can be aggregated nicely, e.g. using a command like this:
zcat ${file:?} | grep -vE '^[0-9A-F]{8} *$' | uniq -c
Consecutive frames of equal input state will be represented as a single row,
with a repeat count giving an idea for how long the state was maintained.
RAM cartridges implementation
Many RAMCART and one SiDiCar cartridges
Support for writeable cartridges
CART monitor command
Make blank cartridge UI option
Reserved CART file ids for additional cartridge types currently unemulated by Atari800,
added also the description of the types
added XEX reading in monitor (useful for patches)
Added H: device rename; save it in setup file
Changes:
Altirra OS updated to v3.41
Altirra BASIC updated to v1.58
Fix buffer over-read in generate_partial_pmpl_colls
Atari ST/TT/Falcon optimizations
Version 5.0.0 (2022/05/28) - released at Atariada.cz (yay!)

MAME 0.261 will be the final MAME release of 2023, and it’s a real
ripper! We’re ending the year with a bang! Over a hundred pull
requests were merged this month, including several from first-time
contributors as well as many familiar names. Following up on the
work last month, two more Casio Phase Distortion synthesisers have
been added: the high-end CZ-1 keyboard and the unreleased MZ-1
module. The Yamaha MU50 XG tone generator module is also working
a lot better in this release.
Two home consoles with drawing features are now working: LJN’s
VideoArt from 1987 and Sega’s Advanced Pico BEENA from 2005. Although
they were both positioned as intellectually stimulating consoles
for children and both had drawing features, they couldn’t be more
different. The VideoArt was universally derided for its poor controls
and lack of entertainment value, drawing negative comparisons to
the popular Etch-a-Sketch toy. On the other hand, the BEENA was a
high-quality device using media combining a ROM cartridge with a
picture book, and featured dual pen digitisers. Its ARM CPU is
fairly demanding to emulate in MAME, so you’ll need a fast PC to
run it at full speed. We’re aware that the current scans of the
picture books are not perfect, but it’s still quite usable apart
from some peripherals that aren’t emulated yet.
On a completely different note, some of the Taito gambling and
medal games have started to come to life. The purpose of the games
is to separate you from your money, and there isn’t much gameplay
value, but they’re still interesting to see. Some of them feature
characters from popular Taito franchises. Speaking of gambling
games, a couple of Chinese-language mahjong gambling games from
BMC have been dumped.
Systems with AVR8 CPUs now run up to 50% faster, including the
Uzebox console, Linus Åkesson demos, and the homebrew Sega Master
System paddle controller. A means of dumping the microcontrollers
Jaleco used for protection in some Mega System 1 games has been
discovered recently, allowing the protection simulation code to be
retired for 64th St. - A Detective Story and Big Striker. Our
understanding of the gate array protection used for some other
Jaleco games has also improved. The internal Super A'Can now has
its main CPU’s internal ROM hooked up properly, improving the
accuracy of its boot process.
Of course, there’s far more in this release than we have time to
talk about here, including newly dumped Korean versions of arcade
games, bootlegs from Spain, support for PDS cards on the Mac
Quadra/LC 630 family, more Heathkit Terminal Logic Board variants,
and lots of new software list items.
