    Hi fellow newbies.

    The solutions I found for Task 1:

    Helpfile: - The registerd-dialog uses a case-sensitive name field
    and a 16 digit hex code as serial#.
    - The registration code is only for the name you registered it for. -> Every name has a unique code.
    - "Degrading" to Windows 3.1 by a file called MEMO.INI

    Regmon: - Starting the unregistered version of Memory Game 95 there's one important value that M.G. 95 reads out:
    HKEY_CURRENT_USER\Software\Kertes Gábor\Memory game 95\Settings \Registration code

    Regedit: - In the HKEY_CURRENT_USER\Software\Kertes Gábor\Memory game 95\ key are several other values. Most are only for the general settings important. Settings\Registration code should be the
    serial# you entered, Settings\Registration name should be the name that generates the unique serial#. -> If the code-value is empty, the name isn't checked like we see in Regmon when
    we start it. If we enter any fake code for this value, Regmon shows a access to Registration name by M.G.95.

    W32Dasm: - There are several harcoded strings, we could attack using W32Dasm. There are:
    Sorry, the registration code does not match (Messagebox)
    Thank you for registering (Messagebox)
    Unregistered (string in about box)
    evaluation copy (string in about box)
    Registered copy to (string in about box) Registration code (Registry key)
    Registration name (Registry key)
    Unregister... (Menu text)
    - The Sorry... message appears twice -> could be checked at the start of the program and when you enter your serial#.

    The two registration values mentioned above are empty if you use a unregistered version of M.G.95. If we enter any values for these keys, and restart M.G.95 a dialog window appears saying that there's a wrong serial#. We should reenter
    our serial. The same dialog appears, when we try to register M.G.95 the normal way (Menu: Register). This underestimates my supposition that the serial# is checked twice. There is another dialog saying that there are some options that are only enabled in the registered version, when you try to use 2-player-mode or the last two card sets. This is another point we can attack with crack.

    Bye.
