New SAV Game Editor - TCG
Here's the latest TCG Editor v1.01 for Civ III saved games. Here's a list of the features:
Change victory conditions
Change forced retirement date
Modify treasury gold for all civs in game
Reveal the entire world map
Works with versions 1.07f and 1.16f (pre and post-patch)
Change the Player's Civ
New in version 1.01:Change the random seed stored in the game
The zip file has 2 files in it, the executable and a help file. The help file is a little thin right now, but it's there for future expansion. There is NO UNDO function, so be sure to save edited files under a new name. I don't recommend editing important SAV files and saving right back over them.
All you have to do is unzip the 2 files into the same directory anywhere you like and create a shortcut to the executable file on your desktop.
The editor is statically linked, making it a little big in size, but with all the different versions of Windows out there now I figured it might be better to avoid any dependencies on installed VC++ runtime DLLs. As a result, it should work on all versions of Windows that Civ3 itself does."
In case I never got the file correctly from Apolyton here is the download link from there:
