All classic systems work great with one exception: N64. Sixaxis works fine, though, and it was pretty neat to play Killer Bean Unleashed with a controller. Mario 64 and Zelda were fine, but my 2D games and the hybrid 2D/3D are unplayable. I assume it is because of the higher resolution screen as my NookColor plays them with no issue. I really wanted to play Killer Instinct Gold and Mortal Kombat Trilogy again! Paper Mario is just sad. My N64 broke years ago and playing them on the Nook or PC just aren't as satisfying as hooking this to the TV. I'm going to rip a couple of my PSX games and try them out later. I'm ready for some decent ROMs to come out to increase the performance. Maybe if the Tegra3 wasn't throttled at 1.3Ghz there wouldn't be any sluggish issues. Anyone know of a proven overclock method?
