im going to start collecting DSiWare, i bought some on 3DS but now im wondering if i should have them on a DSi XL instead. i CAN transfer individual software From Dsi to a 3DS in the future, but it will ERASE ALL SAVES. i only have one shot at this. i need to make the decision beforehand because, 1. you cannot transfer from DSi to another DSi 2. you cannot transfer from 3DS back to DSi 3. you cannot transfer from 3DS to 3DS (5 transfer limit, no Custom transfer, erases previous software) DSi ware is locked to the one DSi, so when my DSi XL eventually wears out ill have to transfer it to a 3DS anyway, which will erase all saves. - DSi XL screen is sharper and crisper - 3DS blur's/smooths the DS image but holding select lets you display it in a sharper but DS Lite sized image. - 3DS has Analog slider, a godsend for RPGs and racing.
