Custom VM protection I am developing. You can find the source code here, but I encourage you to attempt getting the key, or devirt, before looking :)

crackme552_2 on 2:03 PM 10/26/2024: Hello, OP here, I forgot the password to my original account LOL. dev0, you are correct, I accidently created multiple keys when trying to add source code level obfuscation, sorry about that. Thank you everyone for your kind words regarding the protection. I intend on updating it, but started 2nd year university and thus not much time :P.
