We received a message awhile back (sorry for the delay) from one of our players about a way to play to Therian Saga under Linux using Wine. We tested it and it's really great, not only did he explain to us the way to do it but he created a full package with everything needed to do it! Even if you are not a Linux superuser (i'm not) you can install the package and have Therian Saga running in a few minutes.
I personally tested the latest Ubuntu and Peppermint (peppermint is great for older computers):
The first thing to do is to have a Linux computer.
Then you download the package: https://www.dropbox.com/s/k8rxvyu9y162y ... ar.xz?dl=0
You extract the package somewhere and go to the 0_setup forlder.
Open the README file and follow the instruction there.
I think the author of the script will continue to improve his package based on your comments, let us know if you test the package and the result you get!
