Applies toTMNF

TrackMania Nations Forever (Nadeo, 2008) is a racing game built on Nadeo’s GameBox engine. Its tracks are map files in the engine’s GBX format. Sourced · GBX.NET

The facts recorded for it come from the Steam install (Nadeo.ini version 2.11.16): the 2,572 GBX files of its packs and its 65 campaign maps, read with a strict reader and compared with the reference reader GBX.NET; and from map files downloaded from TrackMania Exchange (the 100 most downloaded of all time, the 100 most downloaded of 2026 and the 100 newest). Some of those maps were made with TMUnlimiter, a community extension, and carry data the stock game does not write. Observed
