I have a DSL with an EZFlash Vi. I put NES DS on it. The emulator runs some ROMs fine, such as Kirby and Super Mario. However it freezes up at the very beginning of Zelda and Zelda II, and Punch Out looks like utter crap and is basically unplayable. I've downloaded these three ROMs as [!] versions from more than one source with no luck. Is this just the way it is? Anyone else have success? Should I be using another NES emulator?
