good luck. Does you Dell freeze up right away? Mine goes about 5 games (or 4-5 plays of the same game) before lockup & soft reset the Axim.
This is free, beta software. You should be happy that it exists at all. If you don't like it, YOU should reprogram a new version. All of the code for Mame is available online. I spent a lot of time testing various roms, sound, etc, on a Axim and, well, the version is the same since January. I don't complain, I don't program, I just enjoy what it is.
