Link doesn't work anymore
"www.gametreasure.de is unavailable or may not exist"
I had also found a way to patch the steam version up to 2.29.
Basically I used a program to extract the .exe (7zip I think it was) and then once extracted I pasted the contents into sacred's install directory. I will test confirm this if I manage to get my hands on the patch.
Update:
Found a link for the english version of the patch here:
http://www.sacredvault.org/forum/index.php?action=tpmod;dl=item46 (Just seen that Thorium had posted it above should've read the thread properly)
Attempting to apply to steam version now.
Update 2:
Unable to patch as I did before, I think the patch is in a different format as before I recall it being just a single exe file.
