Older than a year and no feedback at all. :-(
I know its not simple and there are some nice tricks, but nothing impossible ;)

Is anybody working on it right now?! (You might pm me.)

Ok, i'm working on this and i have to admit that is pretty hard, with a very lot of temporary patchs(needed to debug the app), i'm able to see the 'interesting part' of this crackme. Now it's time to understand this 'interesting part'.

Anyway, this is a very good crackme.

Its nearly three years old and still no solution. I already kept the file intact and even linked dynamically ;)

Hope someone will will accept this challenge!
(I developed another crackme which should be even harder...)

Well, limiting the cracking to GPL-licensed tool narrows the number of people who will actually do it. I, for one, will try to make a keygen, but due to tools i'm using not being GPL-licensed, i definetly won't write a tutorial ;-)

But i'll have a butcher's :)

So, lets allow all tools and programs under a osi certified os-license, or tools written by yourself.

What tools are you using?
