Theese are my current supplies can you tell me what i can use and what i can't?
Heres The List:
Back Shell Of A GBO
Power Joy NOAC
Broken Spider-Man GCN Controler (Main Stick Is Broken)
An Atari Flashback 1 Controler (Disasembaled)
Intellivision 10-In-One
Killer insticnt PCB (SNES)
Tact Switches
NES Controler
Mini-speaker
Personally, I'd use the Power Joy and the NES controller, and then get a HipGear/Intec screen pad and shove it in a Game Gear or GBO. Or you could always do a different case, but that's just my opinion. And what battery are you planning on using?
