Do I need 2 microsd cards one for each card or can I use the same one? And what size does the one for the setup need? Thanks.
At the moment, a 4GB MicroSD will work fine for every game released up to date (if you use the ROm Trimmer Tool). If you already have one, I recommend you not to buy more until we know if MultiROM will be supported on GW 2.0.
