Well, what can I say? Such VM, much reverse! :)
What started out as a simple writeup for a simple crackme, became a rather lengthy writeup/rizin tutorial, so kudos if you've read through it. I hope you enjoyed it (I know I did), and maybe even learnt something from it. I've surely learnt a lot about rizin during the process, and I've even contributed some small patches, and got a few ideas of more possible improvements.
