What is a .SMC file?
SMC is a Super Nintendo game ROM, named after the Super Magicom copier.
- Did you know
- The SMC name comes from the Super Magicom, a 1990s device for copying SNES cartridges.
- The .smc copier added a 512-byte header to the dumped cartridge, marked by the bytes 0xAA 0xBB at offsets 8 and 9.
- The Super Magicom let people back up or pirate SNES cartridges to floppy disk in the early 1990s.
- What Analyser reads
- Inspect game ROMs, patches and engine assets: iNES/NES2.0, Game Boy/Color/Advance, SNES, Nintendo DS/DSi, Nintendo 64, and Sega Genesis ROM headers (title, mapper, region, checksum); IPS/BPS/UPS/PPF patches; Doom WAD lumps; Minecraft NBT/schematics and Bedrock bundles; Aseprite sprites; Godot .pck; Quake/id Tech PAK/PK3; Source BSP/VPK/VTF/VMT; KTX/KTX2 textures; Tiled maps; LÖVE games; PICO-8 carts - plus MPQ, 3DS/Switch and Ren’Py/RPG Maker identification.
- Depth of analysis
- .SMC 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 .SMC file
- Drag a .SMC 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.
