A friend lend me his MiSTer board and as I had a lot of time because of various restrictions due to corona virus (here in Greece) I ported Lion to the mister board.
Most things work well but there are some differences in keyboard behaviour and so to play the games well you need a usb joystick, also there is no serial port and XY-Display support as in the original Lion.
VGA output is a bit dark and redish I don't know why. (now fixed)
HDMI is better but both outputs are darker than in the real Lion computer (now fixed).
You can find the core in a zip file at the files section.
