I tried an ATR of SSI's "The Cosmic Balance" with the latest version of Atari800win. Seems to boot and load DOS but the screen blanks and nothing happens. I played with all the settings, but no luck.

What surprised me was... MESS had no trouble with it! I don't know who coded the a800 driver, but it's fairly primitive compared to Atari800win. But then this SSI title is pretty primitive as well.

Any ideas why this won't work on Atari800win?

The game enables a POKEY timer interrupt at a very high frequency.
The emulation of POKEY timer interrupts is inaccurate in Atari800 (Win).
A workaround is: press F8 and type:

c 10 40
cont

I guess MESS doesn't emulate POKEY timer interrupts at all.
