Great work converting MAME to handheld CE

A keyboard input would definitely be great.

Note to Techmaster: currently on Jornado & targus keyboard, these keys respond: [5] adds coins; [left arrow] moves left; [right arrow] moves right; [p] pause; did not have any luck with up/down or fire buttons though.
