• Part of the autorun fixes (see catalog/amsdos_catalog and format.c) are inspired on the great work of Frédéric Coste (Fredouille) on caprice-forever.

The core works pretty well and give the fantastic ability to use the RetroArch Shaders.

Usage

Launch a TAPE (cdt), DSK or M3U, and game should autostart.

Game Database

Our game database is based on clean-cpc-db. A database that has checked every game so that you don't have to spend whole day of finding the correct and functional version of your favorite game. In clean-cpc-db you'll find only clean versions with no weird intros or menus, just working games!

Due to the creation of this database, we have started a small game mapping project, to bring an easyest CPC plug and play experiencie! You can help us...

• Contribute with your RMP files (Work in Progress).

When a game is detected as a clean version, a green disc icon appears at the bottom.
