Palm Treo 800w + emulator Help

[Guest conway]

I just picked up a Palm Treo 800w. I have been looking for a GBA emulator. Right now I have GBACE. The program will start up, and I can go through all of the settings. Although when I attempt to load a rom it gives me the option to find GBA/GB/or all files, yet it finds no roms. I also can not change the directory of where I want to look. Any help with the GBACE?
