Why is n64 emulation so bad in particular? I got my girlfriend one of those handhelds preloaded up with roms and although I haven't tried any n64 games it seems to run other 3d games from other consoles of that Era fine. Also I remember having an n64 emulator on my modded original xbox that could run games fine, I played through all of mario64 on it during quarantine before I built a new gaming pc. I feel like handhelds should have similar power to an old Xbox by now but maybe not.
