3 Dual Screen
Game Boy Advance
The most successful hand held console in history. I was never really a fan of this hand held, it had very average sound and the screen was very watery. It was only when the Game Boy Pocket (GBP) came out that I looked into buying one of these things. GBP had a much better screen and it was much smaller too but still ran all the same games, then the Game Boy Color and Advance etc..
Strangely in Japan they called these games Nemesis (previously used only for Europe released games).
