It's been two and a half months, so I decided to do a bit of updating on Doors CS v4.0. For this half-minor increment update, I increased the speed of the mouse cursor roughly 11x using direct input instead of a ROM call. In addition, I added 8-direction mouse movement: up, down, left, right, and four diagonals. I am also working on Ion and AShell compatibility and support for compressed programs. The TI=83+ version of Doors CS is also progressing nicely; keep your eyes out for that soon.
