as for being faster, yes, but the edit screen lags too much, IMNSHO

yeah, that seems about right... how's about using the graph(ing) mem for
the background? (perhaps release 2 versions?) it'd save a lot of bytes...
removing the editor and such...

I still think it's great that someone did this prog, and that it's pretty
damn good, too.
