Due to popular demand,
here is a modified version of Wouter's slic file which switches the disband code so that it activates upon the discovery of an advance, rather than the game turn.
Now, Ancient age units are disbanded at the beginning of the fourth age with the discovery of Gunpowder, and the code then proceeds as usual, ending with Renaissance age units being disbanded upon the discovery of Cybernetics.
You will need to unzip the file into this folder:
C:\Program Files\Activision\Call To Power 2\ctp2_data\default\gamedata
When downloading, right-click and save as "MM2_SLC_Wouter.zip". This has worked for me. Let me know if you have any problems.
