I am considering buying a 8 bitty from icade and was wondering if blutrol was compatible and/if i can use it with the gba emulator
It is as it uses the standard iCade keyboard protocol, which BluTrol is compatible with. Highly recommended!
Both are good controllers but I would go with the Gametel controller instead since it has a spring clip at the top to hold your iphone in place (kind of like a psp on the go). It uses the same iCade protocol and is the same price on amazon. With the 8-bitty you need to prop your phone up on a desk far away.
