[HELP] executing a code in multipalyer?

hey guys,

i know the game is dead and very old, but anyway its still fun to play.
I want to ask for a maphack/generell hack for multiplayer.


My problem is whenever i change a value i get an out of sync error for multiplayer.
How can i disable this sync function as a host. is it even possible or can i just read
memory but not write to it?




Can you give me a tutorial onhow to do a maphack?
i cant find a generell tutorial because all i find are specific ones...

also A tutorial about externally executing a cheat code would be nice as it maybe works here.
In Singleplayer you can type in a code in chat to reveal the map.
Can i reverse this function to work in multiplayer?

PS: my english is not the best. Dont judge^^
