It's possible. Just not possible with this file... I have added a check to prevent people from hosting lobbies since it causes problems if the lobby ID is bad. If you spoof the lobby ID to a valid one so the native game client doesn't kick clients out of the game, you will be able to host. I might add functionality to edit the lobby ID with an INI file if I update this.
You don't need to use this since MW2 aloes you to still play online with a VAC ban on the game.
You can not just play MW2 with a Vac ban. Idk if you understand this. They recently fixed vac bans so we need this dll patch to play again. So no we can not play with a vac on 1.2.208. It will continue saying steam connection error. So we want a dll patch for 1.2.208 too so we can use liberation and modloaders again.
Had some time over the weekend and decided to take a closer look to see what can be done about the "steam connect failed" message that VAC- banned players are getting. I was surprised to find out that there are some serious vulnerabilities in the way call of duty validates its players with steam. Long story short, I was able to create a patch that will allow you to play multiplayer despite being VAC banned.
What this WILL let you do:
Join games in online matchmaking
Play solo private matches
What this will NOT let you do:
Join other friends
There are some limitations to what you can do, since there is no way to create a valid steam lobby as a banned player. You can however, join other players hosting "VAC- secured" servers.
To use, just inject the .dll file.
After injecting you will be able to enter the menu and join a game.
