From C64CG website, "This game is pretty self explanatory. However, you need six disks (apart from the one containing the game itself) to play it. You can make them using the "install" program on the icosd.d64 image, however, since it might not work on all emulators (or if you're lazy), the pre-prepared discs are included in the zip as well. The game itself is the "THEGAME" program on the icosd.d64 image."
