Black screen on Neo Geo Games?

[Ghoost]

So I just got and set up my Mister and used the update script. I loaded some roms into the Neo Geo games folder and the core recognizes the roms. When I attempt to load a rom, it shows some loading bars in the top left corner, and then stays at a black screen. What am I doing wrong?

Have you got the Neo Geo bios files in there as well?

I was stupid in that I ran the update script, not the update_all script. All good now. Thank you!
