according gateway site, version 2.0b2 is gonna support emunand > 7.0: so i want to buy phoenix wright: Dual Destinies. if the 7.0 emunand works, i can safely buy it and play it right? is there any problem that GW users encounter when buying game off e-shop? (like accidental systemNAND update, or save failure, etc? ) also, i think i need to buy new SD card because 2GB isn't enough for PW, and i have to do all the EmuNAND formatting again right?
