The game code that was breaking was found but the root cause of what the emulator is doing wrong hasn't been identified yet.

    Reject internet, embrace man. TBH it is not usefull at all, it is just in manual or embedded in kali, like basic webshells for example.

For everyday use https://book.hacktricks.xyz are the best in my opinion.
