Nice collection, how does rogue squadron run? I remember #2 was really buggy on the GameCube version

Why not all 3 options, sell a controller with a removable, rechargable battery pack & able to play with a cable in while charging, and if you remove it it leaves room for batteries instead.

Batocera has been pretty great for organizing and playing retro emulators on cheap consumer hardware like a raspberry pi, works with my preferred controllers like leverless for fighting and something like this for everything else
