BF 1942 SWoWW2 demo fixed exe

[evewasdyn]

I am running a demo server. But i wanted to made some server sided changes to the map. Making vehicles team used only. And making a "death bubble" around main bases. To stop base rapping/vehicle stealing.
It works fine on the full version of the game. But i wanted to add it to the demo server i run. But i now see that there is some kind of "checksums" thing. And the game /dedicated server crashes when started. I assume this is to prevent adding more maps to the demo, from full game.
Is there a way to change this sum to a new sum. So the game will play my modded map? Or even just remove the sum thing altogether. I assume its in the game.exe. And you guys here know your thing.

And PLEASE do not insult me, by saying i just want to add full game maps, to the demo. I have 4 copies of BF for my LAN. And 1 swoww2 and road to rome. My kids enjoy the demos map. And i see no need to run another full game server. When there are 1000 and only 6 for the demo.
