VirtualJaguar BIOS?

Trying to do what I can to cleanup/backup my …\system folder, and I’m running into a wall at the very end of my core list.

I wasn’t able to find (in the forums, the core info file, documentation pages, or even my own …\system folder) any mention of the actual file being used for VirtualJaguar’s BIOS option.

How is this core using BIOS if there’s no BIOS file to place in …\system? Is it just an internal HLE BIOS? Those don’t typically come with bootup sequences do they?

I’m just a little confused.
