The Virtual Boy has no boot\nROM: the V810 CPU executes directly from the game ROM mapped at\n0x07000000. Load() in libretro.cpp:490 takes only ROM data.\nUpstream Mednafen supports an optional vb.pal palette file\n(Documentation/vb.html), while the libretro port handles palette via\ncore options instead.\n",
