So far so good... I couldn't get the game to run at anything higher than 640x480(other res crash the game) but I found a user made patch on some site that supposedly allows you to run at any res you want, and fixes the dual core issue. I cant tell if the patch worked, because after applying it the game's video resolution options become corrupted, and ONLY show the 640x480 option, but it does seem like I am not running at 1280x1024.
I wanted to DL the "upgraded" textures from the TTLG site, but most links there are long dead. Guess the forums is my last option.
