Why no one has ever thought about this possibility?
Max yang is 2.147.483.647 (signed-integer), though we can get more than this one 'cos IT IS signed then we also have negative yang but who really cares? It works like that:
Metin2 yang = from -2.147.483.647 to +2.147.483.647
My conversion = from 0 to +4.294.967.295 (negative + positive values added)
How to? Just convert signed int to unsigned int (no negative)
It is possible by an easy hex editing of game file
