Teserae may have been popular with Mega STE owners, but it required no such machine. It is perfectly happy to run on a standard ST, I don't know if there are any memory requirements. If you want to run it in an emulytor, be sure to choose one that does the overscan well. The Steem Engine is one such. Teserae is interesting as an early example of the type of psychedelic Tetris that would get quite popular on the PC—about five years later.
