Cars Video Game Modding Wiki
Advertisement

At the moment tools are somewhat limited for the series. Currently the only games that is documented as actually supporting modding with existing tools are Cars and Cars: Mater-National and only the PC, Xbox 360, PS3 and GameCube versions. That being said research is ongoing and pages will be updated as new discoveries are made.

  • QuickBMS is a generic file unpacker/repacker that works via scripts created for it. Use it in conjunction with this script to extract RES files and Cars: Race-O-Rama PSR/XBR files. Currently it is unable to recompile either, but that permalink will update should the author update the script. Use this script for Cars PSR/XBR files.
  • The cars-research repository on GitHub, which contains a collection of open source tools, scripts, and mods for the Cars games. Some of the things that can be found here include: a command-line XBR/P3R extractor, a database of all(around 80%) of the filenames in the XBR, a BPB->PB converter, scripts for converting generic images to GCT and converting GCT->TEX0 and vice versa, a BINMCF extractor, a script for merging DSPs into ITLs, and a couple of in-development code patches. (The ones currently uploaded specifically target the Wii and use GCTRealMate (not related to the cars-specific texture format!), and they focus on adding characters to the DialogueList so they can have a voice at the character selection screen.)
  • XMA Transform or ToWav.exe will decode XMA --> WAV.
  • Cars archives can now be rebuilt using RePACKER
  • Blender, which when used with the Cars-related add-ons found here, allows the user to import/export animations from Cars: Mater-National and Cars: Race-O-Rama. To download them, simply download the MOTLib.py, MOT_EXPORT.py, and MOT_IMPORT.py files, pack them into a zip file, and install the zip file as a Blender add-on in Preferences.
  1. Advanced features aren't currently needed, so any old editor will do. This will be used primarily for renaming things like materials and bones for a given character.
