I hope to release the Joystick version tomorrow. Fire button double-click will act as right mouse button (to bring cards directly to the foundation pile).
Thank you!! Solitaire Mouse version worked great on my MiSTer FPGA Commodore 64 core. I ordered a Commodore PS2 mouse adapter so I can give it a go on my Commodore Ultimate 64. :) The game looks good and plays very well.
