I have bought a R4i SDHC before, it is very cheap, but when the DSi upgraded to 1.4 version. Then the console didnt support it . So i think i could buy a higher one. I am consideing m3i 0 and dsonei now, could you guys give me some suggestions. I have bought a R4 DS at $ 5.95 for my brother some days earlier from Zero shipping zone very nice guy , and fast shipping. free shipping.
