Alternative Multiclient Solution

[Blequi]

PS: All applications like NeoMC, XenoMC, BlackdMC and these 2 solutions I mention modify the client and there is no MC that doesn't do it. some MC applications like NeoMC and XenoMC modify the memory of the Tibia Client whereas others modify the physical file.

XenoMC does not modify any bit in the Tibia Client, it's a OS level feature. It closes a mutex that the OS maintains and the Tibia Client has not to do about it. The Tibia Client just checks this mutex's state that tells if you can open a new Tibia instance or not.
