Hey there is a similar topic here: http://gbatemp.net/index.php?showtopic=72872 . Basically I have a nds lite with a 3 in 1 expansion pack V. I tried running a gba game off the m3ds real(I have a 8gb micro sd). And it could not find a slot 2 card. Every website I have gone to either hasn't given me an explination or has ended up confusing me more than I already was. I'm a n00b at the ds scene. If anyone can foreward me to the sites that could help me play gba games and use the expansion(for browser), and the rumble feature that would be great. I need a somewhat of a step by step explination of what I need to do. Youtube videos are a good idea but I haven't found any for m3 real. My aim is p0wwww. Another question I have and I have searched this as well and that is how to emulate snes games so I can play(mainly) mario hacks like kaizo mario on my nds. Thanks in advance.
