Colossus v4.0 has a catastrophic bug, in which it can lock up endlessly (most likely while the computer AI is thinking to move), v4.1 fixes this by changing just 2 bytes, the only instance of $D0 $FE changed into $EA $EA to make v4.1 which was patched, not recompiled. And, the text for "4.0" changed into "4.1", text is only seen by pressing the Spacebar (plus, seen on a loading screen for this cassette version). Right now Atarimania has only the cassette v4.0 and none v4.1, I'd leave exact instructions how to edit the cassette to become v4.1 but cassette images possess internal checksums which would also need adjusting, so forget it. Better off finding the DOS file version 4.0 and editing it.

Very good chess program. Quite strong as opponent.
