Code: C++
Protection: just math... it should be easy... oh and the looping music might make you go made during debugging
Type: Console keygen
Solution: MAKE A KEYGENERATOR FOR IT

That means NO PATCHING, NO SERIAL FISHING

And since i know half of you won't listen, I'll ruing patching or serial fishing for you;

Name: zart
Serial: 2832864628

by peeking at address 00401241, the cmp EAX,EBX you can see your serial that you passed in - and the serial it being compared too;

EBX=CFA21F6C
EAX=A8DA1574 = 2832864628

You could patch it by making it;
cmp EAX, EAX
or
cmp EBX, EBX

So - now that i've ruined patching or serial fishing, do what the actual program is ment for, and WRITE A KEYGEN for it.

It's not a bug - run it in a command prompt, it outputs a goodboy or a badboy. it's how ollydbg works - it terminates after the program is out - if you ran it normally (the one way would) it prints out and returns to the system

It wasn't my "team source" (learn English), it was a random source I got off internet. And we're back again at the JEW thread. "SunBeam, teach me how to crack bla bla bla!" (and he doesn't even remember what source I was trying to fix...) PFFF...

EDIT: Took me a while, but here it is:



Result:



Funny thing about it - for Kaspersky, serial is 121 Very Happy
