CaveRace is a classic maze-based video game I developed back in 1997 with some other students. Inspired on a game, I played on my Commodore Amiga, called Dyna Blaster (Bomberman).

Story
On the planed Eldora, there are miners collecting gold and diamonds. When the miners get unexpected visitors from outer space, the mining of precious minerals is in danger. The only defense the miners have is their explosions to make a way inside the mines and caves. CaveRace is a game where you collect as much as possible precious minerals and destroy all alien visitors.

Borland C
The game is mainly written in the programming language Borland C 3.1, and some graphic routines are in x68 assembly language. The minimal system requirements are an Intel 80386 IBM compatible PC running MS-DOS and VGA 320×200 pixels (Mode 13h) in 256-color mode video system.
The game is using your mouse and keyboard for navigation and gameplay. The game loop is in sync with the refresh rate of the screen, not the best choice, but simple to understand. No sound is present in the MS-DOS version, later on, I ported CaveRace to Windows, this version has upgraded graphics and sounds (explosions).
There is also a MapEditor available to create levels yourselves. Let me know what you have created.
Graphics
The original artwork is created on an Amiga using Deluxe Paint in the file format IFF (Interchange File Format). The game CaveRace is using a binary RGB byte file format. Game tiles (16 x 16 pixels) and screens (320 x 200 pixels) are converted to this binary RGB byte file format.
