What is the latest version of Medieval: Total War?

[Thrillology]

For the regular game, I lost my Gold Edition (?) game (thrown out on accident).

So, I am wondering- what is the latest version (update/patch) of Medieval Total War? I want to get the modification started! :D

I am experienced in modifying Medieval 2: Total War... but... made the game a monster and doesn't work anymore.

I can't seem to find a patch- it either shows Medieval Total War Gold or Medieval Total War Barbarian Invasion or Medieval 2: total war

Edit:
Whoops! I meant for the original Medieval, the first Medieval total War that came out. (WITHOUT Gold or Barbarian).
