Hi,
I think I managed to get it, but it is a files collection that first needs to be written on a floppy disk (see chess.doc).

Using WinUAE emulator I usually play some chess games, where the program is already on a floppy disk image (.uae or .adf); yet I am no Amiga user and I have no clue how to create an Amiga floppy disk image, format it then import the files into it.

Should anyone know how to, please give it a try and feedback!
MfG,
Tibono
