personally I like http://crackmes.de ... if you download a few cracks and the solutions it serves well as a tut. get the newbie ones with nothing but a "keygen me" or "find the serial" with no protection... it will be easy to do, but the point is learning. You could just google for debugging tutorials...

I sugest you learn:
Nopping
Code-caves (simple ones at least)

and if you're really ambitious:
dll injection (have to know code caves)

tx a lot man.. ill use it.. i have downloaded some test keygens and stuff.. but somestuff it is hard to understand..

like example this section:

00403026 . /0F84 CD000000 JE abexcrac.004030F9 JUMP IF USERNAME IS AT LEAST 4 CHACTERS

ok is telling me this and whoever made the tutorial knows that is what that section means.. but if i open a program ill just go past it cuz i didnt knew how he got there.. you know what i mean??

ill try out your stuff

what you want to do with those is break the program right where they did... and watch the registers... (ollydbg is better than CE for this) what will happen is you'll get push's and pop's where you'll see the username show up in the registers (EAX is a good one) and then you'll know that EAX is the username...

now when you see "cmp eax+[EBX+08]"
then after a "JE 004030F9"
JE means jump if equal...
so if the EAX (username) is equal to whatever is in [EBX+08] (arbitrary location in memory) then jump to 004030F9...
Otherwise it will keep running through the program.

dammit... i am beyond noobness ...XD ....

I read the tutorials then make the keygens as they explain... but when im on my own i am completely.. hoplessly... noobly lost !!

Man this is frustrating...

And i want to learn cuz i wann apbe able to bypass the trial periods and keygen making... ill keep trying.

Search for:

ASM tutorials
keygen tutorials
crack tutorials
code injection (one of my favourite... make a proggy keygen itself)

hey last question.. i have an application that has the key entry on a dll file.. i found it and edited the jmp.. but i save all modifications to executable and i still get it back like if it doesnt save it..

After i " saved modifications to executable " i close everything and reopen the dll file and is back to normal.. i dont get it.. it should have been saved with the changes..

anyways this is not cheat engine material and i am sorry but the topic went in this direction if you wanna help thank you in advanced..
