Aaarrgh... did you use that in a program too?
I think it would be very cycle-consuming to do this.

Come on, on the C-64, it couldn't have been THAT tight! Except, maybe,
if you used it for packing playfield levels?

Uh... that reminds me of my "Mario & Yoshi" port I did on the Sharp
PC-E220 - in Basic. I think it still lurks around in its memory. I

In case you didn't notice, all files since the start of the list are
stored at the Stella Archives at

there - if you got full Internet access, not only E-mail, that is.
