I wonder if I accidentally made one of my development libs require 10.5;  thought I'd been careful about that!

Sure enough, this is exactly what I had done;  the previous OS X builds all required OS X version 10.5 or later.  I believe that I've now fixed it such that any OS X version 10.4 or later will work.  Can someone who still has Tiger installed verify that for me?  I don't have anything to test it on. 

(Download link is in the top post;  it's version 1.0.7)

I didn't have time to play, but I can confirm that it now loads and games start on 10.4. Thanks!

Sadly, nothing happens when I try to run it. I'm running Mac OS 10.4.11

I tried running it with terminal when it didn't work and it quit with "Bus error"

If there is anything else you would like me to try, please let me know.
