MAME Testers - ISSUES

09483: (btoads) graphics issues

Mon, 08 Jun 2026 19:37:30 +0000

See the screenshot 1 below. Pimple's skin and life bar color are correct.

Stage 2 the life bar color is wrong, but in the boss is correct.
See screenshot 2 and 3.

Last stage life bar color is wrong with strange low brightness.
See screenshot 4.

09482: (vendetta2pp) graphical bug where it says "credit" during the boss description of stage 2 and stage 3

Thu, 04 Jun 2026 14:10:11 +0000

Graphical bug seems to only affect the Japanese 2player version called Crime Fighters 2.

09481: (crankyc) This machine isn't Cranky Condor.

Thu, 04 Jun 2026 09:52:36 +0000

This machine isn't Cranky Condor, but its sequel, Cranky Contest.

09480: (144 games described as "manufactured by Taito Corporation Japan") The notation "JAPAN" is unnecessary.

Thu, 04 Jun 2026 07:08:33 +0000

The "Japan" part of "Taito Corporation Japan" is not part of the company name, but rather indicates the country of origin.
Therefore, "Japan" should not be included in this company name.

This is different from case #02187 (Technos Japan is the official company name).

09479: (lb186) Unable to boot a floppy disk

Thu, 04 Jun 2026 01:51:58 +0000

This system is marked as working.

According to the manual, the system waits for a boot disk and will then boot without requiring further intervention.

There's no software list, so I tried my only LB186 disk and it didn't boot. The system is also supposed to be able to use standard IBMPC boot disks, so I tried a number of them, without luck.

09478: (wangpc) Won't boot floppy disk

Mon, 01 Jun 2026 14:34:09 +0000

This system is listed as working.

This machine requires a floppy to boot from at start.

But it just sits there.

09477: (dgnalpha) Regressed, no longer usable

Mon, 01 Jun 2026 14:02:16 +0000

System is marked as working.

When started it says to press B for Basic, or D for disks.

When B pressed, it says "Going into BASIC" and hangs.

When D pressed. it says to place system disk in drive and press Enter. If boot chosen from software list the screen gets corrupted and hangs. It should go into the DOS version of Basic.

09476: (hp64k) System Master Controller not working

Fri, 29 May 2026 14:41:39 +0000

This system is marked as working.

According to the software manual when this system is switched on you should get a prompt. However it says

UNABLE TO BOOT: WAITING FOR SYSTEM MASTER CONTROLLER

and cannot do anything. I tried a few boot disks but made no difference.

If you go to the DIPs you can see that the controller is switched off. If you turn it on, MAME unexpectedly quits without a message.

If you instead change the System source dip to Performance verification, the diag screen appears. From there, press F1 a few times until it says SYS BUS TEST. Press F2 to begin the test, and once again MAME shuts down.

09475: (nrallyx , nrallyxb) wrong DIP switches for bonus life and difficulty

Fri, 29 May 2026 13:14:37 +0000

That game damaging CRT with catchy music are with invalid and wrong DIP switches for "bonus life" and "difficulty".

DIP Switches values for 1 and 2 lifes are invalid. The minimum number of cars are 3.
The bonus life sets used in MAME are correct in gameplay, but in service mode are listed with invalid values.
The first value is MAME DIP switch and second is the value listed in service mode.

1 car medium 20000/80000 is 88000 FD0000
20000/100000 is 21000/5E0000
20000/120000 is 15000/00000
In gameplay are 3 cars

1 car hard 20000 is 88000 FD0000
40000 is 21000/5E0000
60000 is 15000 00000
In gameplay are 4 cars

2 cars medium 20000 is 10000
40000 is 20000
60000 is 30000
In gameplay are 4 cars

2 cars hard 20000/80000 is 10000
20000/100000 is 20000
20000/120000 is 30000
In gameplay are 3 cars

3 cars hard 20000/80000
20000/100000
20000/120000
MAME bonus life settings are wrong
20000/80000 is only one bonus life for 20000
20000/100000 is only one bonus life for 40000
20000/120000 is only one bonus life for 60000
In gameplay are 4 cars

The settings below are with correct values in both gameplay and service mode listing the same value.

3 cars easy 20000/80000
20000/100000
20000/120000
3 cars medium 20000/80000
20000/100000
20000/120000

4 cars easy 20000
40000
60000

MAME settings "1 car medium" and "3 car medium" are the same value for number of cars and bonus life.

Fri, 29 May 2026 13:10:39 +0000

09471: (pi4d30) Black screen

Fri, 29 May 2026 12:46:06 +0000

This machine is marked as working.

I think this must be a mistake, as the only rom is a no-dump, so how can it have ever worked?

09470: (indigo_r4400) Black screen

Fri, 29 May 2026 12:27:53 +0000

This system is marked as working.

The other system in this driver, indigo_r4000, starts up and shows a screen.
I don't know if it actually boots as there's no software list and I don't have a hard drive image for it.

09469: (ibm5155) Keyboard not working

Fri, 29 May 2026 11:00:06 +0000

This machine is marked as working, but no longer does.

09468: (palmiii) After first click it makes a continual sound

Fri, 29 May 2026 10:49:21 +0000

This device is listed as working.

When turned on it wants to configure the touch screen. After clicking, a stuttering noise starts up and never stops.

09467: "output" doesn't draw text

Thu, 28 May 2026 22:43:25 +0000

"output" cheat code draws text on the screen. But this function doesn't work in 0.288. This happens in built-in cheat with 0.288, no problem 0.287 or plug-in cheat.

09466: (alpinerd and clones) When the finish line track is visible from afar, it initially appears as completely red polygons.

Thu, 28 May 2026 16:13:24 +0000

When the finish line track is visible from afar, it initially appears as completely red polygons. Red polygons don't appear up to the official version 0.287. Possibly related to this: https://github.com/mamedev/mame/commit/cdea363c3eae1a019474ed2bf05880f16be31f21

09465: (ct486 [dune2 software]) Rare freezes on Dune II last mission (sblaster_16)

Wed, 27 May 2026 17:50:45 +0000

This happened to me only two or three times for an entire playthrough (segmented, played over a few days. Host system turned off/on for each new segment recorded), and only on the last mission.

09464: MAME no longer attempts to "create" sockets when using socket.
: syntax with the bitbanger device

Mon, 25 May 2026 18:41:22 +0000

Previously, MAME would attempt to open an existing file, then attempt to create a file. It now only attempts to open an existing file. This means it will only create a connecting socket, not a listening socket. It affects Linux as well as Windows, although the error number is different since it’s implementation-defined (generic:107 on Windows, generic:111 on Linux).

Relevant verbose output from MAME 0.281 (working):

:tty:null_modem:stream: attempting to load media image socket.127.0.0.1:1234

09463: (popnrun,popnruna) "Yukai Tsukai" is NOT the name of the developer.

Thu, 21 May 2026 15:35:57 +0000

"Yukai Tsukai" is the title of an unreleased Japanese version.

09462: (swa,swaj) wrong year

Thu, 21 May 2026 07:38:03 +0000

This game was released on April 27, 1994, not 1993.

09461: (500gp) Trackside animated jumbotrons have wrong colors

Wed, 13 May 2026 04:36:44 +0000

Starting from updates that fixed tachometer needle placement and other graphical things in 500gp, the animated jumbotrons on the trackside now have wrong colors, all displaying heat yellow/orange.

09460: (snes [zombiesu]) Squirt gun doesn't make a sound

Tue, 12 May 2026 19:46:53 +0000

No sound from default gun (squirt gun) and confirmed with video of other emulators that it should be making a sound.

09459: (snes [skyblazru,addfamu, possibly others]) .inp playbacks desyncs

Mon, 11 May 2026 19:53:06 +0000

.inp playback is sometimes unreliable on snes, though this is kinda rare and somewhat random.

For context, I have successfully recorded and playbacked 2h54m dkongcu, 1h50m svania4u, 1h39m addfamu (this one .inp used to fail playback at times in the very beginning, but I eventually got it to playback, and couldn't get it not to playback anymore after that) and 1h02m alestej.

skyblazru seems more prone to cause desyncs.
I've attached 2 skyblazru .inps, entire playthroughs that eventually desync (reproducible each time I've tried (two or three times each)). They desync after a very long time playtime (>> 20 minutes) so you'll want to use max frameskip + fast-forward to reach that point.

I've also attached an addfamu .inp (an entire playthrough as well) that may desync in the very beginning, in the first minute of gameplay. As mentionned above, I can't get this one to desync anymore, but it might "work" (I mean not work) for someone else.
