Hey guys

I've got one of those cute little Picade cabinets and I was about to sit down for a session with Afterburner, only to find it doesn't boot. If i select it off the menu it looks like it tried to load and then POP I'm back on the menu. I have both the Afterburner and Afterburner2 zips on the SD card.

Am I missing a BIOS or something perhaps?
