Motorola Droid X

i downloaded the lite version of the app and i downloaded a couple games. when i start the app it tells me i have to find the BIOS file but im not sure where in my phone the games were downloaded to. For my other emulators(snes, nes, and sega) the roms go to my rom folder or to my download or downloads folder. Anybody that can help or offer any advised would be greatly appreciated. Also does anybody know how to get the net play to run smoother? Thanks once again.
