I have an OLD dos PC that I would love to put a few GOG games on. I also have a special windows 9x computer to put games on though the installer GOG uses causes it crash even though the games would work perfect on 9x. It really wouldnt cost GOG any extra to do this!

Don't know if that possible. GOG games has been tailored to run on modern PC. (XP and above)

Hmm.. as many of GOG games uses DOSBOX so you could just install the game on modern PC and copy game directory after to the old PC. Game should still work with no problems.

Never going to happen, they're not going to create a new version that they have to QA for the small number of people that are going to use that rather than play on newer hardware. And that group is likely to be constantly shrinking as old hardware continues to die.

Just extract the files from the installer (it is a package after all).

I don't see why not. All the OP is asking for is to include the original version of the DOS game. As kavazovangel points out, the installer is probably only a package that extracts the original game and DosBox. Even if it does more than that, GOG should be able to provide the unmodified original they used as a base for their own version, unless there are legal objections against it. They wouldn't have to create a new version at all, that's the whole point. (After all, if the Abandonware sites could do it for free and without any work involved, why shouldn't GOG be able to do it?)

But maybe the problem can already be solved by copying the files, as others suggested.

The topic has come up in the past and it's not going to happen. There's support issues and in some cases licensing issues that come from providing the original files. On top of that many GOGs from the DOS/Win9x era won't even install on modern hardware due to them using a 16bit installer.

The few people that need those files can generally either buy an old copy or extract the files themselves.

Extracting from installer doesnt do the any reg edits that may be needed

Did DOS have a registry?

That would be just great - but as mentioned - gog stated clearly that it's not going to happen.
For pure DOS games (running DOSBox) you can just copy files and run install file to specify configuration (in most cases it's only sound/music card). For games from Win 9x era you could install them on XP, use some installation analyser to see registry entries made by game, export them in legacy Win9x/NT format and transfer game files & those keys on Win 9x machine. Should work fine for majority of games.

Noone was talking about modern hardware, so in that regard I think we're talking past each other. Anyway, if GOG already made an official statement on this topic and said it wasn't going to happen, because there's serious work involved, and it's partly due to licensing issues, then that's different. I can accept that.

If your old PC is DOS based you do not need about such things. You could just copy/move most files between directories without any trouble.
Worse thing to worry about could be to correctly setup autorun.bat and config.sys files - it was kind of magic for many people at that old times :D

Many Windows games don't need registry entries either, some do though.

No.

Yes, but you'll never know if the game uses it or not without some testing :D
For DOS games it's just 100% true. ;)
