AdmiralMemo: How does this work when you already have DOSbox previously installed? I have DOSbox 0.7.4 installed, but whenever I try to install Dragosphere, TeenAgent, or Tyrian 2000, the installation button is grayed out. How do I get these games installed without having to install multiple copies of DOSbox?
It's been a while since I investigated this but IIRC the installer doesn't recognise newer versions of DOSBox than the one in the installer.
So if the game comes with 0.73 you need to point it to a 0.73 install
I haven't tried it (I'm a big fan of sourceports and the like) but if you install DOSBox 0.73 you should be able to make all GOG games that use 0.73 to share that one.
Edit: Just did a quick test and Battle Chess SE comes with DOSBox 0.72 and only recognises a 0.72 install. So possibly the best thing to do would be to install DOSBox 0.72, 0.73 and 0.74 and point each game to the appropriate one
