Various open-source projects

Major and minor contributions over time

Too many projects to list, so here are a few: Diannex is a custom scene/text scripting language for use in games, and UndertaleModTool/DogScepter are modding tools and libraries for games made in GameMaker.


...Along with some other projects:

  • FunManipulator, a tool for manipulating and predicting RNG in speedruns of video game Undertale.
  • SpritesheetWorker, a small but useful tool for splitting texture sheets into individual frames.
  • General technical research and support related to the GameMaker modding scene — besides work on UndertaleModTool and DogScepter.
  • (Completely for fun: bug-hunting and research for multiple games.)
  • Work on multiple other games and fan-games over the years.
