What flash cart is good for the DS Lite? I plan to buy a DS Lite off my friend instead of him trading it in when he gets his 3DS. And, just to make sure, a flash cart runs a game exactly as if the cartridge is in there, right? Like Wifi and everything works... just wondering because downloaded PSP ISOs don't always work 100% and even if the DS isn't the PSP, similar problems could come up.
