yes pokemon black and white works fine, you may need the exp patch, but apart from that it works 100%, i even trade with mine online
i have english patch v3 on my r4 christmas edition, with pokemon black, i needed rudolphs child play patch ontop of this to use the union room but so far works great no freezes and ive just done the 5th gym
did anyone want me to upload the setup to mediafire. mind you, you need to copy the contents of the zip file to the root of your card exactly, back up and delete everything there at the moment apart from nds games
bump for anyone who has problems
