I've got an R4 clone (R4-III SDHC) working fine on my DS lite and I'm buying a TT card soon. I was thinking to give the R4 to a friend but the problem is that they have an DSi. Now I was wondering if instead of buying an "R4i" card could I just change my card to work with DSi? I don't know, maybe with a change of firmware or some sort? Many thanks. ps; I'm a noob and it's my first post. so go easy on me.
