    I've used a small, free game called Team Jumpers as the donor game. Depending on your bandwidth and distance this method might give you noticeable input lag.

Edit: Just saw Chiko's solution is allreaddy implemented in the mods menu and files.

the first one we tried 10 times and nothing happened (LF2 lobby dosent work anymore as i can see [or maybe you know something else and can help me with it ?])

anmd the second one i dont really understanding what he is doing there
