you can say me, how you create your SQ server for VC-MP, if you do not have source code of 0.3z r2
VRocker and Maxorator, (as well as the LU and VC:MP teams themselves), have a trusted, cross-assistance relationship going on from which VC:MP allowed VRocker to re-release 0.3z R2 with some bug fixes and Squirrel support. It's not a new version...rather more of a support update to the same version.
Actually...
When i first made the VC:MP Squirrel server i did it with a lot of reverse engineering and a thorough understanding of how VCMP works as well as understanding the netcode from making the mIRC dll.
I originally made it to test how viable Squirrel was as a scripting language for games while i was researching its use for LU. The idea was to test it with VCMP then release it before LU so people get used to the language. It was originally a separate executable using the rcon interface (yucky i know) but i had a crazy idea to make a new server and the Squirrel server was born!
The trusted thingy between me and max just allows us to share information and some experimental methods of hacking GTA. When we released the server i did let the VC:MP team know but i don't think they approved of it and i don't think they thought it would become as popular is it is and tbh neither did i.
