Usefull for those of us that dont like seeing a bit sticking out of our systems perhaps, it doesnt bother me but some may be annoyed by it, heres what they say:
1. The real size of GBA card.
2. Build-in rechargeable battery design. Work with SuperPass 2 only need to Setup at the first time.
3. Support all most 100% NDS games.
4. NDS GBA linkage function.
5. GBA game save more compatibile because of battery design.
6. New shell design, more beautiful than SD version.
7. Directly plug and insert design. MiniSD flash card insert and plug out without remove MiniSD Supercard.
& now for that all inmportant question to be answered...
