Multiple Key Presses

[clax]

I was wondering if there's a tweak or workaround for my HTC Tilt 2 that would allow multiple keys to be pressed at the same time mostly while using emulators. For example, I'm having a hard time finding a key configuration that allows me to press every combination of up, down, left, right and ABXY. Alternatively, I could use a suggestion of a key configuration that avoids any conflicts (right now I'm using W,A,S,Z for up,left,right,down respectively, and the arrow keys for ABYX. Thanks for any help.
