How come my roms don't show up??? HELP!

[yyzzpp]

I have instaled rockbox on my 5th gen 30g ipod and i know that there is rockboy and iboy emulators for it. Ok here's the deal... I downloaded my gameboy rom and made a folder in my ipod directory to put my game in. But when i opended rockbox and browsed the files i found my folder but no roms. I have also tried Iboy but no roms appear for it either... I have read all the manuals and looked at a lot of blog's and stuff but cant seem to find and answer. So does anyone here have an answer?? Why don't the .gb formatted roms show up?? HELP!!!!

Make sure that Settings->General Settings->File View->Show Files is set to either "All" or "Supported"
