well i got a dsi and i had a ds lite case and when i put the dsi in the ds lite case it fits but the sides of the case the stiching around will show a little but it will fit.!! answer my quest abiout justin biber lol i'm so bored
yes i made the mistake of buying a DSiXL case for my DSi and its too big (duh) so if u do buy a new case check the size. (even though you dont need too because its the same size)
