hi i have an Nintendo Ds Lite and im interested in getting a gba flash cart.. just to play only GBA GAMES! i also dont want the cart sticking out.. so far ive read around the thread that ez4 lite is a good choice. but im also confused with super card. and what they do.. do i just need the ex4lite itself to be able to play gba games? or do i need to flash/ supercard to be able to play flashed gba games on NDS lite?
