How did you take that screenshot? I don't remember any WB1.3 compatible screenshot programs. That must be WinUAE! (oh the horror...)
Edit: Updated screenshot. Reason: It sucked. (to paraphrase a Simpsons' quote "...boy, that screenshot sure did suck. It just plain sucked. I've seen screenshots suck before, but that was the suckiest bunch of sucks that ever sucked."
This is still a 100% real unedited Amiga 500 16 colour screenshot. And for people who like periodic tables (who doesn't
like periodic tables?
) here's CDB.
