I've worked on it quite a bit, but I finally got it finished. Allow me to introduce my first crackme! Written with love, care, and assembly language. I think I made it quite complex (if I were to solve it from scratch, it would have taken me a long time 0_o), but the feedback from those who solved it will show that. I implore you to try it out!

I wanted to try writing my own custom mini-obfuscator — it turned out to be a small 60-line Python script that handles gcc's output. While I was testing it with print("Hello"), Defender suddenly woke up and declared that we don't do that here. So, if your AV starts complaining, just turn it off or switch to a virtual machine — although there's only this harmless crackme inside.

Actually, why not turn this file into a task? It'll be a clear example of how even external packers/protectors can sometimes fail to protect a file from the programmer's own carelessness. The goal is to extract the music into a correctly playable audio file.

P.S. I don't allow the process to simply record audio—it's not interesting. Think your way around =]
