Yep, this is a very nice interface !! Congratulations ! It's another milestone in C64 tape gaming since .tap Images, I would say.
I wish I had something back then, because then I hadn't been in need of a C2N tapedeck.... Now I have tons of them and even don't know where to put them all
Also, Akira is right about Lemon64 Forum. It is simply too reapeating for people who have been there for a long time ! There almost no day goes by where no question like 'What is the best 10 game' and such is posted !! That's cool for people who have just re-discovered the C64, but boring for others.
I only occasionally check the boards over there, and almost only post in hardware-help threads.
