Here are a few game-specific utilities I wrote primarily for the purpose of hacking. The only programs that are supported have an accompanying readme.txt file included.

All files with source code include a license file. Read it first before viewing any source code.

Note: Most of these were never designed to be “user-friendly”. Use at your own risk!
