I wanna trade my WII for 3DS so i wanna buy an Flash Card so i could play DS games on it. I saw an dude here selling an R4 Dual Core Card so i am asking is it good? The 3DS is on the lastest firmware updated. Is the card gonna work? Does all DS games work with it? etc. I am newbie at it and idk anything about DS/3DS Hacking so say anything thats important for it.
