Since you can use YSMenu on an R4, is it possible to use any firmware on an EDGE card? I want to play PBR, but the EDGE doesn't support Wii connections. If it's possible to use any firmware from any given flashcart on an EDGE, can you give me a tutorial on how to do so? Google returned no answers. And by the way, should I buy a DSi and an AceKard 2i and sell my EDGE to someone or buy a DS Lite? I need a new DS since I have an original DS that can barely last a car trip on a single overnight battery charge.
