No BIOS or firmware files required. This core is self-contained.
Libretro port of Mednafen's Virtual Boy emulation module. No external BIOS or firmware files. The Virtual Boy has no boot ROM; the V810 CPU executes directly from the game ROM mapped at 0x07000000. Load() in libretro.cpp:1787 takes only ROM data. Upstream Mednafen supports an optional vb.pal palette file (Documentation/vb.html); the libretro port handles palette via core options instead.
