I have a flashed DSL and a Supercard Lite, and everything works perfectly. I am getting a Supercard Lite Rumble and a SuperKey for my cousin's son (young kid) for Christmas, but his unit isn't flashed. He is in a different country, so I'll be shipping the stuff across to him with instructions to his mum on how to use it. As my DSL is flashed, I can't test it or see what happens. So, just so I get this straight, what happens is... 1) You put the Superkey in 2) You put the Supercard Lite Rumble in 3) You turn it on Then it boots straight to the Supercard file selection menu right? I will be updating the firmware and putting games on a MicroSD card for him, but I just need to know that using it with a SuperKey is this simple, and whether there are any issues (apart from reduced battery life) that exist with the SuperKey. And the SC Lite Rumble can play all DS ROMs that the normal SC Lite can, right? It just cannot play GBA ROMS.
