A SuperCard MiniSD:


It's a very easy to use GBA flashcard, just load your GBA ROMz on the MiniSD, plug it into the SCMSD and you can play! I own one and it works perfectly! I haven't encountered any problems, every ROM worked fine.

Visit the official website for more information.

EDIT: I see you want other emulators too, I know a couple which work on the MiniSD. I will list them all.

List of all the emulators you wanted, which work on the SuperCard MiniSD:

• NES: PocketNES
  
• GB: Goomba EMU
  
• GBC: Goomba Color
  
• SNES: SNESAdvance

I couldn't find a MegaDrive emulator, sorry.
