Thanks for the comments. The Exceptions are pretty generic. PocketPC development has no real Exception handling like the desktop developers have. The best that can be done is do a debug run and try to isolate them.
Hopefully future Releases will be better mannered. I am rewriting much of the code based on newer releases of MAME, so we will have to see.

I tinkered with on screen keys but had a tough time wedging them into the core Emulator code. The MAME Engine is very complex piece of code and unraveling the deeper stuff, like after the emulation starts, is a bit hairy (for me anyway:) ).
