So you see, this is quite weird. I've searched around looking for solutions, yet each time I tried installing wood firmware it stucks on loading screen. So I don't really have any choice but to ask directly, do I? Is my R4's a fake? I'm quite confident it's not though this is the picture... okay its not so clear but cart said "R4 upgrade Revolution for DS(NDSL/NDS)", and the microsd is 2gb(sandisc) Is my sd card busted? I'm pretty sure it functions well, since when I replaced back the wood firmware with my old backup files, it worked like magic. So this is my backup files I have(which works like usual...) So whats the deal with my cart anyway? Is it REALLY FAKE?? or is it just wants the old firmware and doesn't like the newer ones? Help anyone?
