>>19335589Well the supercard ds two is a pretty solid flash cart. Most of the roms work perfectly but a few of the once released towards the end of DS's life span still have a few bugs to work out.
It can also emulate gba,gameboy/color roms pretty good and the new SNES emulator they released recently plays some SNES pretty good. The nes emulation is hit or miss depending on the rom but a lot work pretty well. The sega genesis emulator though is awful and unplayable with slow down and glitches. on top of that it has built in cheats for the ds roms so no need for an action replay, not like it would have worked on one to begin with.
It's an expensive flash cart but I still think it's the best on the market.
