The GameBase Frontend
Using this universal emulator frontend, you can download the GB64 database and run it on your own computer. You can also use it to create your own game databases for other emulation systems.

Quick64!
Quick64! is a shell extension utility designed to make it easy to run your C64 game files in a variety of emulators. It also provides an easy convenient way to view the contents of C64 game files directly from Windows Explorer.

Bolyx
Based on the classic 1987 C64 game "Zolyx" from Firebird Software, Bolyx (a remake for Windows) feebly attempts to recreate the addictive feel of the original game whilst adding a silly plot and a highscore saver.
