emulator: Beetle VB (Mednafen Virtual Boy) type: libretro core_classification: community_fork source: "https://github.com/libretro/beetle-vb-libretro" upstream: "https://mednafen.github.io/" profiled_date: "2026-03-24" core_version: "v0.9.36.1" display_name: "Nintendo - Virtual Boy (Beetle VB)" cores: [mednafen_vb] systems: [nintendo-virtualboy] notes: | 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. files: []
