I am planning to get a slot 2 card to play GBA roms (Slot 1 is DSTT) and Supercard seems to be a good choice. however, the are just too many models to choose from. So based on the features, which one is the best? I took a look at the comparison chart here http://forum.supercard.cn/viewthread.php?t...;extra=page%3D1 and it says that SC Lite and SC SD are pretty much the same. Also, what is that "battery" thing that miniSD has? I want a SC that can at least: 1. Link the GBA rom with the DS roms on the DSTT. 2. Save directly to sd card so as not to lose my save game and I will also be able to play it on VBA. Any help would be really appreciated. PS: Will SD and MiniSD run on a GBA SP, too?
