I have a friend who has no PC and very little money but wants to play PSX titles. I'd like whatever routes are possible to include scanlines as the main "shader" effect. The emulation can't be crap. I know mednafen and psx (on pc) are really good. He needs to play on a tv. Does a raspberry pie 3 meet these requirements? (Retroarch?) Wii? (Wiisx?) Can you give me advice about rasp pie 3 and wiisx performance? Other options?
