I've made and added this script earlier as I want to try out the dosbox integration. It does a few useful/essential things for the user to setup the dosbox configuration. However, the one I'm wondering about most right now adds some entries which change the folder mounted as the C: drive. The game fails to load and complains it needs a system.ini file when the wine bottle's C: drive is mounted (the default), but works perfectly with the game folder mounted. Previous posts I found suggest it's not just a problem on my computer:

http://www.playonmac.com/en/topic-11727-Constructor_GoG_Version.html

So I added entires to autoexe.bat to unmount the default and then to mount the game folder. Works well it seems, but is there another (maybe simpler) way to choose the folder mounted with play on linux commands?

All other thoughts on other matters also equally welcome, I'm just focusing on this part of the integration as I couldn't find anything yet to suggest I can change it.

Well, the way I've been told how it works by Tinou, the new DOSBox support must be thought as an augmented Wine support, so for consistency C: maps to $WINEPREFIX/drive_c, always.

So with this constraint, I solved similar cases by moving the files around instead (example Ultima 4).

 

Hi Pierre,

Thank you for your help. It makes sense for the two to match. I've altered  the insaller to do things this way now.
