NeoDS: Help with "Bios ROM"

I just got NeoDS and it tells me that I need a "Bios ROM" to be able to convert the roms. Where do I get this? It sais "(neogeo.zip)" but where's that?

You need to extract neogeo.zip. If you don't know how, go to the tutorials section.

I found the neogeo.zip bios rom, but the converter isn't working. I'll check out that tutorial just to be safe.EDIT: I'm a dumbass nvm.
