Hi v,
I tried out your chess program. Looks great! both piece design and board colors, maybe even Tempodbasic (hello :D ) would like the colors! I like the size too.
What is the difference in the pieces labeled 80 and 320?
I think you could use _LIMIT too because the raggity fan in my new computer kicked on shortly after I started the run.
PS I forgot to mention important feature, it is drag and drop!
