First, Keep in mind that the current build of MameCE3 is based on Older MAME code version .36. So you may need older based ROMs to make games work.
Second, Games that require large amounts of RAM or Multiple CPUs will probably not run. The ARM CPU just can't handle all that work.
Third, Keep in mind that MAME works well on 120Mhz CPU with a Computers that have very advanced Graphic Adaptors. The PocketPCs have NO Advanced CPU or Memory for the Graphics functions. So the overall performance suffers.

Given all that, I am working on a rebuild that I hope will clean up stretching issues, ROM version compatability ,and performance issues.
No ETA yet.
