this is way more than just the file if you loose the .byte file or the password set stored in registry or any major upgrade of hardware like cpu gpu hard drive motheboard you will loose access to the game without any way to go back as the game behavior for bad authentication is to destroy both file and password set so if you dont have backup you are fuckedthey are fully aiming at milking everyone even their past supporters who can lose access to their legit copy access simply by losing a file hidden away.
In all my message i mark that .byte file as THE THING because its the key to open the game an encrypted key but the key is that file thats and encrypted container containing a set a information they use HMAC (Hash-based Message Authentication Code) to authenticate the decrypted data against the hardware BUT they really do that in a weird way they kinda use it in a way thats not how you use HMAC wich make the reverse engineering process kinda interesting.
But WTF they are doing exactly is not that clear i kinda want to see the real source code of that part if it die someday just to see WTF they are fucking doing im genuinely curious to know if its weird because they implemented that without knowledge and somehow make it work in a weird way or just used the thing knowing its not supposed to be like thatbut made it work anyway (if a dev read that you can just answer it without code to im really curious for real that a weird way to do HMAC really)
