Z, i just tried it, i think youor spot on with the vc and FA part....
example,,, in FA with underground 5x zoom etc... you cannot join certain servers... eg.. German TD , Weapon wallet and Watch, But in Normal vietcong 1.6 you can...
Sadly however this doesnt seem to work the other way round,,, ie, when you load standard vc 1.6, you cannot join FA servers such as pterodon BMF etc...
So what file is it?, i dont think its the .dat noobly..... as underground hack worked in both types of games depending on the nature of the server...
All servers seem accessible but it depends on what version of VC u use...
How do we get round this 1??
