are u using HEX editor with Ps_game.exe ???
i think we could do that with more hard work i used Cheat Engine to find more about it and noticed thats when u learn the first skill u will get 1 and the next one 2 even when it was LvL.4 in the game it will be 2 in the hex
so i tryed and made my Strength Training to lvl.7 with the hex edit
so it will be easy for u if u used Cheat Engine
