You do not have to do anything with the exe.

Just add the mods you wish.

Add the blood mod as Gothic Child suggested
You can also find a flag and icon skin pack to change them. Just be carefully with your local laws. There was a reason they had to remove that stuff.

Blood does not come stock with any version of MOH so you did not miss anything there.

Just unzip the mods, They should look like this.

whatever_blood_mod_you_download.pk3
whatever_icon_skin_you_download.pk3

Just add them to the moh/main folder ( you should see all the other *.pk3 files)
restart your MOH.exe and you will see the changes

Good Luck
