So I bought few days ago a supercard dstwo, and I am already playing DS games on it. I also downloaded the snes and gba emulator from the supercard dstwo website. Both folders are on the root of the microsd card, and I download some roms too. But the software doesn't appear in the menu. Is there something else to download?
What do you mean when you say "the software doesn't appear in the menu"? The root of the microSD is the correct place for the emulators, so when your start up DS/ DSi you are saying that you cannot see the emulators when you scroll left or right?
That's odd, i have the GBA and Snes emulator on mine. I haven't come across your problem before, i can only suggest make a back up of your microSD and format using the Panasonic SDFormatter and then replace.
