History
CodeBreaker is a game program that I wrote in the 1980s based on the Master Mind board game. I converted it from Amiga BASIC to Run BASIC and added some audio/visual elements in 2009.

Technical Notes
How well the program works depends what browser you use. If you use Firefox, I recommend downloading a Windows Media Player Firefox Plugin that will allow the audio to work.

The program will not start unless a server on my computer is activated. I keep it running most of the time.
