Don't know if this would be useful to you but for general tweaks, I use K-lite CODEC.
Unfortunately, the support page for Tomb of Zojir***
me additional codec paks CAUSE CONFLICTS - see list below (check your system to see if they are installed)
-K-lite Codec pack
-XP codec pack 2.3.6
-Codec Pack All in 1
-Combined Community Codec Pack
You may need to uninstall any of the above codecs if they are installed on your system. (there may be others not listed above)
So if the game in question is indeed one of the Last Half of Darkness games, I wouldn't recommend installing K-Lite.
