Uuuups, it seems I misunderstood your post.
You wanted me to post some source-
CODE, right?
Sorry, but this is not the right forum to post any code I think.
If I'll find or create something of interest for you, I will send you a mail.
Btw, could you plz send me your unsolved crackme at:
[email protected]
Btw, there are crackmes or reversemes out there, which are harder to crack/reverse than actual copy-protections.
