NeoGeo Pocket Color ROMS

Hi ppl,
Since some time now I've been trying to get any rom working with the NeoPop emulator.
It accepts some formats, but not the most commonly downloadable ''.bin'' files (usualy in a ''.zip'' file.
The zip-files also won't be accepted. I get a: "No roms found <path>" error.
Anyone got a clue?
Thanks!
Stijn
