[BUG] PS2 scratches may not match due to assembler differences #1303

Open 1superchip opened 4 months ago

1superchip commented 4 months ago

Describe the bug Some scratches may not match due to assembler differences. https://decomp.me/scratch/jo4dl doesn't match on decomp.me but locally with Ps2EeAs it does. The code is compiled with a ProDG compiler which was packaged with a custom assembler Ps2EeAs.

Expected behavior ProDG compilers should use Ps2EeAs (the assembler shipped with ProDG) or the assembler should be selectable in the Compiler Options tab.

Screenshots On decomp.me: Note that the Current doesn't use at as the original does. image

Assembled with Ps2EeAs locally: image

Where is this Ps2EeAs binary? are there different versions? do they have different behaviour in terms of matching?
