• 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.

Try some CRT shaders and welcome back to the 80s on your good old CPC.

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.
