Hi Mussolini,

The only important thing that you need to check is that you have the same checksum.

This appears in the top right hand corner of the main menu screen ie FDYY.

The mods that only modify the pictures ie brigades, ministers etc do not change the checksum so you can install, or not, any of those.

The large sprite pack 10.01 does change the checksum because it has a new modified country.csv file attached.

Version 10.0 does not change the checksum so one of you can have this installed and the other MP player does not have to.

As long as you both check the checksum before you start your game there are no problems.

We have a small MP section on our forum and the players have never experienced any issues.

I hope this helps.
