What is a .GG file?
GG is a Sega Game Gear handheld game ROM.
- Did you know
- The Game Gear was Sega’s colour answer to the Game Boy in 1990.
- The Game Gear reused Master System hardware, sharing its Zilog Z80 processor so it could run adapted Master System games.
- Its standout feature was a backlit colour screen drawing from a palette of 4,096 colours.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .GG is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .GG file
- Drag a .GG file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
