After doing a bunch of random stuff I give up. I'm 99% sure at this point you can't assign individual roms different values from mupen64plus.cfg [Video - Rice]

This video is of the PC version. It has the same Reaver blade issue in widescreen. It's definitely the game not the emulator causing this flaw.

@bilboiii when in doubt unplug it and plug it back in

before implementation in pcsx-rearmed it needs the GL pcsx plugins (i believe the PEOPS plugin in pcsx-rearmed standalone is an earlier version of Pete's) working. these will be MUCH slower on a pi than the very optimised NEON software plugin that pcsx-rearmed currently uses.

so, i don't think it would be playable on a pi. you can run a backported version of this in lr-beetle, which is libretro's mednafen psx emulator, which has a PGXP implementation. it runs v slowly on a pi, also.

@peterman only works with certain open gl plugins. i think it's working in lr-beetle, but that's unplayably slow on a pi.
