Can I change victory condition mid-game?

Is there a way to modify a save file (30+ hours of online multiplayer) mid-game to remove/add victory conditions?

E.g. I want to disable diplomatic victory.


I spent two evenings to find this and I do not want the information found to disappear. Did through the creation of new games that differed only in victory conditions. And compared the save files. I managed to change the victory conditions through the save file through the hex editor (HxD)

I find sequences for several types of victories

1) War          00 00 00 00 00 00 00 00 00 00 00 0X 00 00 00 5D 0E B5 18 01
2) Diplomacy:   00 00 00 00 00 00 00 00 00 00 00 0X 00 00 00 AD DD 34 E4 05 
3) Culture:     00 00 00 00 00 00 00 00 00 00 00 0X 00 00 00 D1 22 BE EC 01
4) Science:     00 00 00 00 00 00 00 00 00 00 00 0X 00 00 00 8C FF 43 18 01
5) Score:       00 00 00 00 00 00 00 00 00 00 00 0X 00 00 00 82 4C 6C 62 03
6) Religion:    00 00 00 00 00 00 00 00 00 00 00 0X 00 00 00 D9 DC E5 18 01

Replace 0X to 00(off) or 01(on)


In the same way, the limit of moves is turned off: https://i.imgur.com/4Kfi5Gw.png

on:     00 00 00 00 00 00 00 00 00 00 00 AF F0 F9 DE E7 A4 0A 2A 02
off:    00 00 00 00 00 00 00 00 00 00 00 DE 25 99 80 E7 A4 0A 2A 02

In total, you need to copy the last save file, open it in the HEX editor and change the flags.
