Digger was originally created by Windmill software in 1983 and released as a copy-protected, bootable 5.25" floppy disk for the IBM PC. As it requires a genuine CGA card, it didn't work on modern PCs. Digger Remastered runs on all PCs with CGA or better and plays just like the original. It also has many new features, including: - Exit button - Optional VGA graphics - Recording and playback - Real time speed control - Keyboard redefinition - Gauntlet mode - Two player simultaneous mode
