mame2003-plus-libretro VS alu_cores

Fwiw there’re joystick bootlegs of these rotary stick games, for reference https://github.com/libretro/mame2003-plus-libretro/issues/47

I opened an issue at mame2003-plus github: https://github.com/libretro/mame2003-plus-libretro/issues/1557

The complete meta data can be find in the file https://github.com/libretro/mame2003-plus-libretro/blob/master/metadata/mame2003-plus.xml

FBNeo, MAME (up to 0.172) and snes9x uses non-commercial licenses, and probably a few others i forgot about.

Get XML dat file (for 2003-plus) here, elsewhere for other MAME versions.

MAME 2003-Plus is way better read about it here. https://github.com/libretro/mame2003-plus-libretro

For best results, I recommend this MAME2003+ core: https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20211108

The most robust core is MAME2003+. It's the one used for most of the games which come with the ALU and several users have built improved versions. I'd use this one from u/walknight : https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20211108

For posterity, I checked the original UCE from the COX v5 pack. It ran. So then I rebuilt it with the latest core from here using both the original AddOn Tool and the much better tool created by /u/meepowl. Both of those ran as well.

Pull the UCE that won't save from your drive, extract the contents to a folder, and rebuild the UCE from the contents. If the game is using a MAME2003+ core, replace the original .so file with this one: https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20210521.4

Take a look at this for proper syntax and config options: https://github.com/wn2000/alu_cores/blob/main/mame2003-plus.md

Could you post instructions on softreset? I tried burgertime , using cheat.dat from https://raw.githubusercontent.com/libretro/mame2003-libretro/master/metadata/cheat.dat and latest mame core from https://github.com/wn2000/alu_cores/

It's due to yet another incompatibility of the built-in retroplayer with the libretro cores. Try the latest mame2003-plus core here, where I've put in a workaround. FBAlpha/FBNeo may also work.

Here is a link to the core. https://github.com/wn2000/alu_cores/releases/tag/mame2003_plus_aarch64_20210521.4

Good question. Please take a look here: https://github.com/wn2000/alu_cores/wiki#when-building-a-uce-how-do-i-change-default-core-options

So, if you have One saUCE running which uses RetroArch, or just want to test your luck to see if latest retroplayer fixes the issue (I doubt it), you can grab the cores from here. I plan to put future builds, if any, on the same site.
