oh yea i get it...
my first letter is I to, so if i see IHHHHHHH its correct Smile that'll take a while but thx =)

btw,
countless != inifite
countless is a number humen cant count to... like 4 digits after google O_o (google = digit+100 0's O_O_O_O)

btw, u tried every combination untill u got the good serial? which is 10*26*2*16 :O numbers, letters, each digit, there are 16 digits O_O

No he was saying thats the newbie way. If you want the better way, find out WHY PQ = I. Then you can just put the algorithm in a program you make, and generate it for you.

it is a newbie way... becuase im trying untill now for like 30 minutes and non of my combinations worked >.<

try the better way now =)

umm got any hints for that..? =( how can i know even if i see it =\ i dont know how the calculation works so if i see like ecx+eax*14-13C i wont know that this is it O_o

umm edit:
i think smilie is instead of letters... or else I for me != PO but for SunBeam it is :O so... this is wierd O_o

If you don't understand whats going on, get out you need to learn assembly.

Step through it one line at a time, write down whats happening to all the registers and what the command is doing. Perform it by hand - and understand what it does, THEN you will understand how it works and how to reverse it.

Reverse engineering is NOT just peeking at values - it's UNDERSTANDING where to peek and why you can peak.

Anyone can tell a monkey to look at eax at a certain break point, but the monkey doesn't know why it has to look there or hell - what it's looking at!

ok.. i know assembly pretty good but going through every address manualy? wouldnt it take hours?
well i found that edx is the edit box of the serial, the value of edx is the 2 digits i wrote, it changes each 2 digits i mean...
also found that h is n for me (in sunbeam's serial its h for spaces, so its n for me, i guess that will help a bit)

alright im not gonna be that monkey! im gonna be a smarter monkey :] *manaic monkey lough* :]*2
ill try going trough each address now...

look at some of my previous posts.. i posted snippets of asm, and i even commented them.,.. it shouldn't take hours - and as you get better you read the code faster.

plus once you figure out the pattern it's easy, maybe two times through and you should get it. it's a loop - thats just doing the same action over and over anyway

At first I did it the newbie way, but going like 2-3 times through it, I managed to find a quicker way (zart showed it to y'all - besides, even the input buffer tells you what to look for in order to 'adjust' your inputs) Wink Why did I do it the nooby way? Guess everyone of us, every now and then, needs to do stuff the hard way - either for fun or for good laughs - in order to get some good brain stimulation. I was curious whether my *guessed* combinations would be valid or not. And as I stepped through trying to match combos, I developed an affinity to the algo itself Wink What followed - you'll see soon...

And yes, I didn't count the possibilities, but there are a few (every letter in that hash string can be obtained from at least 100 combinations of 2 letters or 2 numbers or 1 letter + 1 number) Very Happy
