On the edge...

    Ok...this is very frustrating and I think Jeff will agree with me...

    I read everyone's posting, see what they have done... And the only more detailed posting is by noos. Giving a breakdown of the asm commands. No offense meant to the rest. Although the rest did explain the results they got BUT the results are no help to me (and maybe Jeff) at all!!

    But in the end, after reading all the postings, I still don't know HOW to go about doing it. I tried IDA, debug, W32dasm, Softice, even by just staring at the HEX values in a hex editor. I used all these tools because that's what the postings said. Nothing works. I can neither redo what you guys did because no instructions given, nor able to try it out on my own.

    Yes, I can copy and paste some of the keyfiles that are already done into the directory but so what? I haven't learnt anything yet.

    Like what I said in my previous post, I keep getting kicked out after the crackme opened the caveman.dat even when I tried using Princess' keyfile!!!

    1)
    I tried changing first 2 bytes to CD03 then change it back, got kicked out...
    2)
    I tried changing the 1st byte to CC then change back, got kicked out again...
    3)
    I loaded the crackme using DLDR.EXE found in my softice directory, got kicked out as well.

    for 1 and 2, I changed back the bytes using "e address" and then "r eip=xxxx:0100"

    I used Princess' keyfile, got kicked out with the message Registered to Princess. Fine!! But I did not even get to the "game" code everyone kept describing!

    I do know the basic asm commands and what ax values with Int 21 does what etc. I've got the Ralf Brown's Interrupt list.

    Is anyone kind enough to explain HOW to crack this crackme? ie, use WHAT tools, look for WHAT?
    Perhaps I should insist that everyone (that is if anyone bothers to post at all after that), should post not only the solution, what they found, but HOW it is done.(I don't mean single sentences like "I use Softice")

    Don't think a newbie is able to learn anything from the way this project is going.
