    Here is a simple solution to the crackme.dat
    This will allow you to put in any name both upper and lower case lettering.
    We will use the name Princess

    Make the .dat file like below

    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    50 72 96 6E 63 65 73 73 00 00 00 00 00 00 00 00

    The second line should have something in the first place, here it is 01 but can be anything up to FF jus as long as it is not 00
    Third line is the name in hex

    Now alter the program slightly

    00401202 83C704 add edi, 00000004
    :00401205 3BC3 cmp eax, ebx
    :00401207 750C jne 00401215 < == NOP this instruction
    :00401209 90 nop
    :0040120A 90 nop

    One more small detail

    004010C7 E8CD070000 Call 00401899
    :004010CC 684B204000 push 0040204B < == change this to push 004025B
    :004010D1 6A00 push 00000000
    :004010D3 6A0C push 0000000C
    :004010D5 FF3559224000 push dword ptr [00402259]

    That is all now any name you put on the third line in the .dat file will show in the window.

    Princess


    Princess
