Hey all gog-fans!

I have an old dos-machine (my dads xD ), and it is fully working. But i like to install some new (old) games on it, and play it on it, instead of running it on my pc, as it is much more fun xD. Is possible to run gog games on it, or is gog games different? It could be very nice if it is possible! Would love to run all my fav games on it!

Best regards xx.

Depends on the game. Some games may be missing some executables (the ScummVM ones for example), others may be mounting a CD image that you will have to burn to a CD to use properly, others may be using a mixed mode CD image that also includes some ogg files, while a few others you may be able to just copy over and have them working. There are a couple of threads (and a youtube channel or two) that give more info, but I don't have any of those handy atm.

I've done this before.

First you would have to install the game on a more modern machine. Then go to the installation location and look at the file names. The files and directories from the original dos games are often in 8.3 uppercase format while the others are in mixed case.

If you only have a floppy drive on your old system, you may run into issues with games that originally installed from floppies. Sometimes a large file would be created by concatenating multiple smaller files from floppies during the installation process. And now, the GOG version only includes the larger concatenated file. In this case, you have to zip the file into multiple smaller volumes that each fit onto a floppy and recombine them when you unzip the volumes on your ms-dos machine's hard drive. 7-zip does this easily on the Windows computer when you manually create an archive, but if I remember correctly you'll have to specify the size. You'll need PKWARE's pkunzip to uninstall on the ms-dos machine, look for the old dos install package: PK250DOS.exe.

When I last installed software onto a 286 laptop without a cd-rom or network card, it was easier to disassemble the laptop, remove the hard drive, attach it by and IDE to USB cable to the Windows system, and copy 400MB of data onto the 504MB C: drive partition rather than setting up a parallel port NIC with a DOS TCP/IP stack, Zmodem'ing it through a serial connection, or <gasp> using PCAnywhere over a serial cable. The cables are inexpensive, I bought one for $4.

YMMV

In some cases, you might find it a lot easier to run these games using FreeDOS on a modern computer. Especially any of the games that require you to free up lowmem.

It surprises me a bit, but it looks like you can't just extract the files using innoextractor, I didn't realize that had changed, or perhaps I'm not doing that correctly.
