You can do what I did for using my M3 Lite in a GBA/Phat.
Take the front half of any normal sized GBA cart, and take the back half of the Lite shell, put the 3-in-1/M3 Lite/etc in there, tape it tight and you've got yourself a Phat compatible 3-in-1.
Sure it looks ghetto, but you're not really going to be taking it out and showing it to people.. are you?
