    Greetings everybody,

    Many times I almost threw the towel and gave up on this most dreadful crackme, but alas, I conquered it, or at least almost did. It is late and I am too tired to say much now, but must tell you that I have figured the access code calculation method and will post it as soon as I can type it. However here is some thing to wet your appetite.
    The access code is a 50 bytes long and it is calculated from whatever you enter an it should match 50 bytes of hard coded access code. Here are the 50 hard code access code:

    D0 6F Bf CC C7 31 B3 C1 EA 99 D7 72 C2 AF DE A0
    4D A6 B0 EA 90 A0 47 96 98 72 D3 51 B2 41 60 E6
    7F A4 CA 5F A0 C1 B3 73 9E 71 49 CD C3 CE B0 77
    B0 F3

    You may find this code at 406120
    The fake access code is at 406314

    The calculation is done on a one byte at a time bases in 50 round loop an starts at 402012

    Place a bpx at 402012
    DB 406314 and you will see the fake code. Modify these 50 bytes of fake access code to match the one I presented above. Be careful not to make mistakes. When the modification is finished continue running the program by entering X or hitting F5 or whatever. In a flash you will be greeted with the "Code Accepted, Thank You screen.

    That is all for now, the rest will follow.

    Best regards,

    Joseph
