Electron-X, the one-man studio run by German developer Wolfgang Rolke, focuses on forensic-level inspection of content packages created with Nadeo’s TrackMania and ShootMania series. Its single utility, Gbx File Dumper, is aimed at modders, server administrators and competitive players who need to verify the internal structure of .Gbx containers before sharing custom maps, replay packs, title packs, vehicle blocks or item models. The program decodes the binary header of any .Gbx asset, exposing metadata such as map UID, author login, environment, medal times, checkpoint count, embedded mod names, thumbnail size and dependency checksums without opening the full map in the game editor. Because TrackMania replays, campaign packs and user-generated challenges are distributed as opaque .Gbx blobs, the tool provides a quick way to audit files for corruption, detect unofficial modifications, confirm compatibility with a specific title pack version or extract embedded texture and music paths for external optimization. Typical workflows include batch dumping an entire server folder to generate a CSV summary, comparing two revisions of a map to isolate header differences, and validating that a replay was recorded on the exact map revision currently on the server. The lightweight Win32 executable requires no installation, opens files by drag-and-drop, and writes human-readable reports that can be piped into further scripting. Electron-X software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the newest build and permitting batch installation alongside other applications.
A little Windows application that displays the contents of the file header of mainly maps, challenges, replays, packs, blocks, objects and items used by the Nadeo game engine GameBox (.gbx, .pak, and .dds files).
