I know hakchi2 allows you to play games from Gensis, SNES, N64, basically everything, still amazes me. What is the best controller/method/combo to use to play all these different games? Do I need multiple controllers, one for each console LOL? Right now I have 2 OEM Controllers from the NES Classic boxes themselves. Obviously, I can't use that controller for games besides NES? All Gen/SNES games where impossible to play when I tried. Castlevania Bloodlines, all I could was jump (unless I have to map the buttons or something?). I was wondering if using my Nintendo Switch Pro Controller and just buying a 8Bitdo Retro Receiver http://i.imgur.com/1G5HdNN.jpg would be my best option, to play NES, Sega Gen, SNES, PS1, N64, etc.? Or would simply buying a Wii Pro Classic Controller be better as that seems like many people's goto controller? Whatever route I go I'm in need of 2 controllers, 1 for myself and 1 for my son.
