I still can't believe I bought an M3 instead of a R4, but then again, at that time I just had no clue...
The point is, M3 isn't getting software update for quite sometime, problem now is, I would like to play the new pokemon (black/white) and I just can't. This because the rom won't run in such software, I already tried to use R4 newest software but I wasn't really successful, if any of you could give me a hand it would be great.
Okay, found the solution! I'll make a quick guide for those who are wondering trying to find the answer like I was, since there is barely anything about it around the internet.
