Car Models

The car models are stored in the C0-C5 folders as .car files. These files contain 3D model data, textures, and other information related to the cars.

Research into the .car file format is ongoing, and tools for editing these files have been attempted with some success at extracting textures, as seen below.

Sound Files

The sound files are located in the SE folder and use .SHB and .VHB formats. .SHB contains audio data, while .VHB contains metadata such as loop points.

Extracted audio archive:
