HamSandwich is a collection of updated open-source versions of several of Hamumu Software's titles from 1998 through 2007:

  • Spooky Castle
  • Eddie Galaxy
  • Amazin' SPISPOPD
  • Kid Mystic
  • Loonyland: Halloween Hill
  • Stockboy
  • Dr. Lunatic Supreme With Cheese
  • Loonyland 2: Winter Woods
  • Sleepless Hollow

The current source code of HamSandwich is available on GitHub. The original source code releases on which this project is based are available on hamumu.com. Assets are pulled from official versions of the original games, available for free from hamumu.itch.io.

Saves and profiles from the retail versions of the games are fully compatible with HamSandwich saves, except that controls will need to be reconfigured.
