If you are referring to fixing the "wobbly" graphics common in PS1 games, this is a hardware limitation called affine texture mapping. In emulators like DuckStation or RetroArch, enable PGXP (Parallel Geometry eXtended Pipeline) settings to stabilize textures and geometry. Multi-Disc Errors: For multi-disc games, use an .m3u playlist file
= re-encoding audio/video to less aggressive settings + restoring necessary CD sectors.
