i have bought an r4 cartridge for my daughters ds and want to load it up with loads of games. i have noticed that you can now buy 6gb and 8gb sd cards on ebay but i heard somewhere that the r4 only surports up to a 4gb sd card. can any body here tell me if this is true or not. has anybody tried using a hi capacity sd card in an r4 revolution the highest i have tried is a 2gb. just need to no the score really to save myself time and money.
