I tried doing this. I created a shortcut to my RTW.exe which went to "C:\Games\Rome Total Realism\RomeTW.exe" -sprite_script. I made a file in C:\Games\Rome Total Realism\ called sprite_script.txt. In that file, I wrote
generals_horse romans_julii generals horse
with that spacing, copied directly from Jerome's post. When I clicked the shortcut, RTW started up, went through the initial loading screen, and then returned me to the desktop almost immediately. The data\sprites folder doesn't even exist. I must be doing something wrong—but what? Jerome, [cF]Adherbal? Any ideas?
