I've encountered a few problems with MAMECE3 on my 3955.

Punch-Out, Super Sprint, and perhaps more, corrupt the display. Either the backlight goes higher, or the screen gets ever whiter, and all sorts of strange things happen. Exiting the game doesn't help - the device requires a soft reset.

Gauntlet crashes the game completly, the last 2 digits in the exception produced was 00000005, which slips my mind at the moment. Few other games seem to just exit gracefully with no errors at all.

Would there be a way to have a couple on screen buttons? If only to insert coins and start the game, I realize that the touchscreen drivers aren't the best, and in many cases, will slow down, but it would really help if you could just disable the buttons in gameplay.

Forgot to mention, I have had no luck using any of the screen rotating functions. Rotate left does nothing, and rotate right makes the screen upside down

The Screen Rotation routines are just hacks into the existing screen code (which was designed to rotate the screen based on the original game). They seem to work about 50% of the time.
Maybe one of the next releases will have better rotation features.

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:) ).
