Hello all mates,

Here is a new keygenme, to warm up our spirit :)

Name: Levis's Simple Keygenme 04

Language: Delphi

Packer : N/A

Level : Maybe 2 or 3 ( i don't know, base on your choice, i think that it's very simple :) )

Require: A valid serial is accepted, but would be better if you can keygen it :D

All bug reports are welcome ( Well, I'm not believe in my coding skill, now it's very bad :( )

Cracking this is fairly simple:

CPU Disasm
Address Hex dump Command Comments
004EDAD1 |. 8D95 F5FEFFFF LEA EDX,[EBP-10B]
004EDAD7 |. 8D8D F6FDFFFF LEA ECX,[EBP-20A]
004EDADD |> 8A1A /MOV BL,BYTE PTR DS:[EDX]
004EDADF |. 3A19 |CMP BL,BYTE PTR DS:[ECX]

Set the cmp to compare to EDX instead so it compares against itself. :)

Working key:

Name: atom0s

Serial: EC5DC97FFC730D00

As for making a keygen, honestly I suck at that lol but I was able to fish one as well as crack it. >.>

@atom0s and T-rad: Thanks for trying my little keygen :)

@atom0s: Your serial accepted, feel free to do what you want :).

@T-rad: Great works, but seem that your keygen not work on my pc, I can't register with serial generated from your keygen. :). Anyway, you worked very hard

@atom0s

spoiling it for others showing that code mate.

not sure if I clicked on report post a second ago, if I did it was accidental.

Added spoiler tags around it to help not ruin it. :P

i think the problem was for boxes that that don't return a string from the API ( <- don't wanna give anything away ) but i think i got it working now.

try this.

Keygen.rar

@ChOoKi, serial is box specific.
