Ok, thx! I hope in Future it will be possible! Corridor 7 aswell! The Capstone Games were nice, would be a Dream to play them someday in better Quality...
Phil, It's been decades since I've been waiting for this, but since their source codes are long lost, this might take a while. Anyway, I'm always hoping that Les Bird eventually finds it and spare us a lot of time... You can reach him in his website: https://lesbird.github.io/lesbirdbio.html
The main reason for it taking awhile is priorities and lack of time. Having mapped out the games in a disassembler I don't think reverse engineering them will be particularly hard. Of course it would still be nice if the source was found/released since it would be a lot less error prone to have it as a reference, but the delta between Wolf3D and these games is pretty reasonable so I don't expect it to be a major roadblock to supporting them.
