Besides the 3DS, PSP, and smart phone, whats the best custom made handheld that is capable of running NES, SNES, Genesis, and maybe even N64? I would like something that is flashy and about the size of a GBA, but with a much nicer screen and affordable. Any suggestions? Or should I just build my own Raspberry Pi handheld...? (If I build my own, I will need a VERY detailed guide as I am no good at wiring)
