What is a .MML file?

.MML is a Marathon (Aleph One) file (Games). Analyser identifies a .MML file and reads the metadata in its header, right in your browser.

Did you know
  • Marathon Markup Language (MML) is Aleph One's XML-style configuration, used to tweak everything from physics to graphics without touching the game's binary data.
  • Bungie open-sourced the Marathon engine in 2000, and Aleph One has kept the trilogy playable on modern systems ever since.
  • The studio behind Marathon, Bungie, went on to create Halo, and Marathon is often seen as Halo's spiritual ancestor.
What Analyser reads
Identify Marathon (Bungie's 1994 FPS trilogy) and Aleph One data files - the open-source engine that runs Classic Marathon, Marathon 2 and Infinity on Steam: scenario maps (.scen / .sceA), physics models (.phys / .phyA), shapes/sprite collections (.shps / .ShPa), sound collections (.sndz / .sndA), recorded-game films (.filA), interface images (.imgA) and MML config XML (.mml). Reads the big-endian wad header version and the embedded internal name from each.
Depth of analysis
.MML 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 .MML file
Drag a .MML 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.
