Honestly I never played Blake Stone, because as the wikipedia entry says DOOM came out a week later. Â Blake is a Wolf3d variant, so I would imagine that the same build environment that can build Wolf3d can build Blake (Borland C 3.1 & TASM 3.1).
An update to the whole thing, MarakaateÂ has fixed the source well enough to compile! Â You can read about his adventure here, and download his updated source here. Â He’s also asked me to plug his BBS, marabbs.no-ip.org .. You can just telnet to the IP address. Â There is some palette issues as they are compiled into the game, not read from the data files (wtf?) and have been extracted from an exe, however the starting logo is all wrong.. But the game works.
