Does anyone know of a way to determine why a particular MAME rom that worked before, now doesn’t? I tried running a log of the error but no errors are output. Basically what happens is I load the rom, it crashes, and Retroarch reboots. I tried rolling back to an older version of MAME, earlier Lakka builds, and other versions of the rom file, but the problem persists. I’m currently running the 9/5 Lakka nightly on a PC.
You need to make sure your ROMs come from exactly the same ROMset as the MAME version reported by the core because MAME is very picky about that sort of thing.
Which MAME version do you using? And which ROM doesn’t work?
Yeah I knew that, but I’ve been able to update the MAME core and the rom would still work. Right now I’m using 0.212 and the rom is RayForce. I haven’t been able to find a version of RayForce that is part of the 0.212 romset. I have other roms that I’ve used on prior versions of MAME that still work fine, like Battle Garegga and Batsugun.
Do you have its parent rom (
Yes. It won’t load on its own either.

If you have the right romsets and they don’t work, maybe there is currently an issue on those games with MAME or its libretro port. Idk since i never use it in the first place.
FWIW, the game should work properly in FBNeo.
Nope, i testet it and can confirm, that all 3 games are working with the latest mame (0.212) core.
I can see already there’s a difference in the romsets, but it still works in 0.212 MAME on my Windows desktop. The rom I have has the following files:
Mine has two “ic49” files where yours has ic49 and ic50. But like I said it still works. I think I might try a fresh install of Lakka.
Worst case I just play the Saturn version Galactic Attack.
@Sivarticus Then you have a pre-0.210 rom.
In the 0.210 release they renamed the ic49 rom in ic50 to avoid duplicate.
Try to rename this:
@ImnoTapLumber way ahead of you lol… tried and failed.
Fresh install worked. It now loads like normal. Not really sure what fixed it, but if anyone else sees this post, might work for you too.
@Sivarticus I’m glad it worked out. I was really out of ideas.
If you sometime find out what was wrong let us know
I figured out what was wrong. So I guess MAME doesn’t like it if you have roms sorted into subfolders?
I had the rom saved as such - storage/roms/Arcade/RayForce/gunlock.zip
Doesn’t work if you store it this way. Once I moved it to just the Arcade folder, it loaded perfect. Now I know.
