I have a DSi XL running 1.4.5U (I just updated this the other day was originally 1.4.3 i believe I bought it used.) I just bought a Supercard DSTWO that is on the way which I am really excited about. I know you can only play DS/SNES/GBA games on there and DSi ware games wont work and probably never will. But my question is can I still go online to the DSi Store and purchase games such as Shantae, Zenonia & Cave Story while the DSTWO still working and able to play the DS games and emulators? And while I'm here how well does the SNES Emulator run?
