Alrighty all I can find are dna or 3.7v nes mods and these are cool and all but I'm thinking about making a mechanical nes mod. That seems like it would be really cool and pretty unique it also seems like it would be pretty difficult considering the nes controller is pretty small. I've never made a mod before but it's a pretty easy small dc circuit. Don't really know exactly what I'd need for it. Would it be better to have a dedicated battery pack or a removable imr?? Any help would be appreciated guys.
