Im analize this game, and here what i get:
Config BD in temp folder when game is install on windows is all clear text.
Gold, bound soul and soul crystal are items. All in this game are item, and the table where it is stored has a column to "type" where those are "Currency".
When we try frida, assembly-csharp functions and classes doesnt work on frida, we need to enumerate all exports, imports and symbols, then analize all and hook it. I cant find any function to manipulate items like: getitem, get_item etc... im spend a little time on it, but in general this game is very hard, not for newbie. Hacking Soul Crystal is possible since there is a vide on youtube where someone did it and give away all sc for players in US server. So, i will keep trying and any help will welcome
