Ah right! For some reason I recalled it being like mosaic (with BG/OBJ bits), but it's just a full effect at the end! Yeah we can just add some routine...

Unfortunately invalid opcodes cannot be just "skipped" or ignored. Theoretically, an invalid instruction should generate an INVALID IRQ that can be handled by the BIOS. (Also note that the definition...

That's odd. Cheats were revamped and did work (I tested them myself). Lemme ask some folks...

Yeah there's definitely a bug in the arm dynarec. However it seems that using the original BIOS works (or at least it doesnt crash on my machine?). The builtin open...

You are reading the code wrong, the cpu mode (it's an enum) is different from the cpu mode encoding (which is indeed 5 bits and its 4th bit is always...

So far I think I identified the bug, sent a fix to GiiBiiAdvance (https://github.com/AntonioND/giibiiadvance/pull/19) gpsp has some other issues since fixing it doesn't seem to fix the mentioned games. Will...

A save file and/or savestate is welcome! Also the ROM hash, since there are too many versions of some games :)

I definitely need to look into direct load for some platforms (like Vita, that has plenty of RAM for GBA). In the meantime I sent https://github.com/libretro/RetroArch/pull/15220 to ensure that low-mem...

Right, it would be good to add a commandline argument to enable/disable this. I agree that it might be good to have it "disabled by default" unless explicitly enabled :/...

Will run a full romset test to verify this works on all roms. Then we can perhaps come up with a cleaner patch. Thank you!
