I'm sorry, but I cannot make heads or tails of what you wrote here. Could you please elaborate?
you said : " Perhaps a simplified method that would only need RedEdit? "
This will not ever be possible as the game does store a set a password in registry that is important but this is not the license at all
the game check for a file wich is located inside appdata also bind the set of password and the file to the hwID of the computer where the licence file is generated
so if i where to give you a good set of password but no file => back to login screen
if you have the file + password but the hwid mismatch => back to login screen again
and if you have the all 3 but the patreonid in the registry is mismatch again => login screen
you need PatronID + HardwareID + password + file to be right for the game to launch offline and the file is generated by the backend of the game "yl2-cloud.appspot.com/verify" and this also encrypt the file wich make really hard to fabricate fake file as we dont know WTF they do to the file to get to this .byte file that is encrypted
the file contain the hardware id the build version and the patreon id also suspect one of the 15 password is stored inside the file but i cant decrypt that file i just know the data that this file contain as multiple variable are set to null if this file disapear or cant be decrypted by the game so i know for sure these data are inside
so if it was as simple as a regedit i will give a .reg file and fly away as i have really limited free time but here i need to patch all the function that check all the shit the game need to check to make the game think you using a valid account that is paid to generate file the account always get banned after i release the patcher so the method need a sacrifice to make the people here play offline
so if you want to fully crack this game you need
To figure what algorithm they use to encrypt the file
send me a PM to say "they use this algorithm"
and if you manage to identify the said algorithm i think i can make a kegen but the algorithm they use isnt easy to identify
