With the help of Tridash, I was able to get CBoE compiled for 64-bit windows! Probably not too much in the way of a point, but native 64-bit binaries for a game released in 1997 isn't too bad
I dinked around and didn't notice any errors, but it's best to be considered experimental. Download the game (with 64-bit boesounds) here.
