Baggins: A few I mention function only on SCUMMVM or only on Dosbox though. But most have a program that they function on just fine.
PimPamPet: I think GOG prefers sticking to one or the other for these collections, not mix DOSBox with ScummVM games. Also, ScummVM is probably more convenient for most people since it's easier to set up (unlike DOSBox, it has a graphical interface).
Baggins: As for PQ1 EGA and Space Quest VGA, and KQ SCI, there are many people complaining those are missing, considering they are practically completely different games, changed puzzles, completely different art, new and enhanced musical scores, new scripts, etc.
PimPamPet: I agree where those games you mention are concerned, but we were discussing LSL6. The difference between the regular VGA and the hires SVGA versions isn't so staggering that this urgently needs to be addressed IMO. Either version will be just fine for most people.
They should have went with the SVGA version, as the VGA version uses downgraded artwork. Since there is no technical problems with the superior version in Dosbox.
BTW, all the Sierra game adventure collections on steam use dosbox, none use scummvm. Unless Larry collection is different?
BTW, as far as I know, the KQ6 comes with both the files for the regular dos version, and the windows enhanced version. Granted to access the enhanced you have to manually on your own get scummVM, and use it to access the enhanced version.
There aren't really that many Sierra adventures that have 'enhanced' version.
