frodo not loading roms

I have used frodo on many systems ps2,Wii, pc and on symbian os. I got an android phone, the dell streak. Got frodo and a bunch of roms on the phone but with alot of them when i select a rom i get a tiny icon of a cd and it says "start the disk (first Entry Found)" so i click on this and it loads the normal load":*",8,1 and then i get file not found error. The roms have worked on all my other systems so i know there intact. Any ideas ?
