Apparently bypassing gameguard is well documented on the internet but it's not what we are focusing on currently. But if someone with the required skills and/or motivation could do that and document it it would be awesome !

I have to add that personally even when TCoS was still up I was unable to launch the game at some point for an unknown reason, a bug never fixed and that I still have. (Error 196).

 

Btw Zer0.BE, do you know how the doors and chairs and interactive level elements were "activated" by the player ? We managed to activate mailbox but the process seems more complicated at least for doors and chairs (and World portals which seem to not be InteractiveLevelElement at all). We managed to activate them on the client (from a programmatic point of view), but are currently searching how to actually open the door when clicking on the radial menu option.
