Can you show a listing of the ROM folder on the Pi, where you copied the arcade ROMs ? If they're not in .zip format, then they will not show up.

@shift They are indeed.

Lots of the emulators don't have "versions" also. The libretro cores are constantly updated etc - there is no such thing as a "version" for many of them.

@dankcushions @dudleydes @MoX Thanks to you all! I appreciate all of your input!!!!
