I'm currently trying to set up Crusader No Remorse on my Galaxy Note III, but so far I have been unable to start the game.

Did anyone here manage to successfully run it on an android device? If so, would you mind telling what you did, step by step?

I'm using Dosbox Turbo.

To get Crusader running on Android in DOSBox Turbo, either enter the following commands manually into the DOSbox prompt or put them in Crusader's autoexec:

mount c <insert the path to Crusader's folder here. Something like: sdcard/dos/crusad>
c:
imgmount d "GAME.GOG" -t iso -fs iso
CRUSADER.EXE

That should allow you to launch the game.

This helped me run the game fine. I was wondering if that "imgmount d "GAME.GOG" -t iso -fs iso" works for all gog dos games you try to run on Dosbox? or is it specifically for the Crusader games only?

Hey, thanks for asking that question! I was recently trying to get Menzoberranzan to run on Android and happened to see your question pop up. Turns out, I needed to 'imgmount "GAME.GOG" -t iso -fs iso' to get it to work as well. It may not always be the right solution for GOG DOS games but it definitely seems to work on the games have difficulty launching directly from their standard exe file.

It varies from game to game, at least in those I have installed. I've seen "data" directory, .gog, .dat, .ins, .inst extensions.

I think the best and easiest way to be sure is to look into dosboxNameOfTheGame_single.conf (in the game installation directory) where GOG puts [autoexec] instructions. It's a ready recipe to make the game working on your system (Linux in my case), all you really have to do to is change paths in .conf files accordingly.
