What is a .SMS file?
SMS is a Sega Master System game ROM.
- Did you know
- The Sega Master System was Sega’s 8-bit rival to the NES.
- The Master System’s Z80 could address only 64 KB, so larger cartridges relied on bank switching to page in ROM.
- Related Sega systems reuse the same scheme with their own extensions, such as .gg for the Game Gear.
- 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
- .SMS 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 .SMS file
- Drag a .SMS 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.
