Just want to sat thank you Gragar for doing this :D
A side project of mine is testing all GOG DOSBox based releases on a real DOS PC and documenting the process. So this list is super helpful.
You're quite welcome. :)
There are also some releases that come with ScummVM, but do have all the game files needed to run them in DOSBox. Dagger of Amon Ra is an example.
I decided against including ScummVM games in my list, because:
1) ScummVM support is usually mentioned in the requirements (unlike DOSBox).
2) Some games, like Riven, are actually the Windows versions.
Having said that, should GOG start getting lax in mentioning ScummVM-enabled DOS games, I may end up shifting the focus of the mix a bit.
Finally, since you are using a DOS PC, you might be interested in knowing (if you don't already do so), that two games have DOS versions as extras but are not included here, because they are just the raw DOS files:
1) Retro City Rampage
2) The Original Strife: Veteran Edition
