Hi,

This code is for my SolusChess board, which does not have LEDs in the squares, and which emulates a keyboard in order to send the moves, and therefore its communication is unidirectional. Certabo is a much more suitable platform for this.

Well, building such full (bidirectional) communication is nothing for me, this would definitely be a task for any MAME developer -
only they know the MAME system very well, have good hardware knowledge and can write the necessary C code much better than me.

And for this they won't even need my CB-Emu version (or its source code) - since all moves are displayed (by LEDs) and made on the external board,
the original (official) MAME version without my enhancements would be sufficient, because in this case the display of chess pieces on the MAME screen
is not needed at all.

Regards,
Franz
