"To further help in the learning, and programming of the Atari 7800, the following original Source Code to many Atari 7800 video games have been provided below. These games were rescued from Atari ST format diskettes that were thrown out behind 1196 Borregas when Atari closed up in 1996. The Atari Museum rescued these important treasures and recovered them from the diskettes. Many of the compiling and coding tools as well as the Atari 7800 development tools are Atari ST programs, which can be run via emulation to be able to natively compile and test code."
