hokay homiez, so this should be pretty straightforward, no antidebugging, get to the keycheck via the usual GetWindowText reference, and a nice ass keycheck routine written in hand-written assembly for your convenience, so no pain there, but writing a proper keygen might prove a little bit nifty.

valid solution is a keygen that generates valid keys for any given name. it is absolutely not necessary to rip any code. the keys will look kinda whack but that's okay, this aint no beauty contest.

a version of the keygenme with the actual keygen included is included, so yall can see that this kgm aint no non-working bullshit. disassembling the keygen kinda defies the whole point of solving a keygenme, so if you do, you must be kinda dum or somethin.

peace out negus

09. Jul 2012		you can patch this program by set EAX=0
I can not wirte a Keymaker, but the register call returns the result by EAX, so if we modify EAX=0, any Serial will be ok!
