CTR-ModSDK

ModSDK. (noun) A toolkit that allows you to create mods for Crash Team Racing (1999) in C.

This repository also houses an effort to fully decompile and reverse-engineer CTR in C.

This SDK uses:

• psx-modding-tools by mateusfavarin for injecting and testing code
• CTR-Tools by DCxDemo for parsing and extracting the game files

📃 Features

• Extract and build ISO in few steps
• Supports all retail versions and two prototypes
• Compile C code into any address and overlay
• Integrated Xdelta patch generation
• Hot Swap: Load code replacements while the game is running

🏁 How to Start Modding

Requirements

• python 3+
• Open command prompt (CMD/Terminal) and install the dependencies:

pip install requests
pip install opencv-python

Downloading the SDK

Clone this repository:

$ git clone https://github.com/CTR-Tools/CTR-ModSDK.git

📊 Progress

Research and Decompilation

Decompiling the assembly assisted by Ghidra, researching how it works and adding comments for guidelines.
