I have a mp4 player ( http://img529.imageshack.us/my.php?i...sdjashdqj9.png ) that only supports NES games... and someone told me that i can play gbc, gb, gba, and snes games... i searched the internet and there such a mp4 that supports those games.. but i cant find how to do.

Is there anyone knows here how to play those game formats...
