There are multiple ways of patching this CrackMe.
One way is a bit more difficult (And I think this was the way you meant it to be patched :) ).
But there's also a much easier way of patching the CrackMe and I think you overlooked that... :)
I'm not going in further detail because it could spoil the fun for someone else, but I just wanted to say this :)

I wish you would have paid as much attention to last string printing as you did for the intial string. That would have sure made it more intresting. The offending byte sems to stare at you face telling you : oh comeon just patch me . Btw i am still puzzled as to why the good job string dont have a line break like wrong message.
Any idea code_inside

Hi Oorja-HalT,

I don't see a problem with both strings, they are both terminated with the $ character :)
There's also nothing wrong with the code which is printing the strings.
Or do you mean something else?

I don't see the problem neither the good msg have "new line" chars (13,10) and yea I'll make it a little bit more interesting in next "version" of this lame crackme and I'll fix the "little" problem that code_inside point it out :)

What i meant is the bad message starts in a new line
Whereas the good message continues in the same line .ie press any key to continue. Maybe this line doesnt have the termination chars.I think i will have any other look sometime
