[using OllyDbg]
hi, i just installed a game , but my cd drive makes much noise when having a disc in and im also interested in RE, so i figured i could try to crack it...

well so far, i have checked the string refs in olly but the cd not found isnt there.

i figured i could use: bp GetDriveTypeA, it works and im brought to this command:

cmp eax, 5

below there is a jnz short...

ive searched a few lines up and there is an test eax,eax command. ive tried chaning cmp eax,5 to cmp eax, 3 and also to change the call that is above test eax,eax to mov eax, 1

after this the game wont even show the cd error, so i figured that this gotta be the wrong ones. but i just dont see any other....

so, anyone knows what the problem might be? ^^

thx in advance..

well is your Game / app protected with any form for anti-copy protection ? and perhaps you could list the code your trying to patch ? with notes fitting it then im sure somebody will be able to help you

ok i used peid and it doesnt show any protection, just to be sure i checked the extra tab thigny and there it says it is paced.. so after a while i checked with aother proggy and it said its protected by Safedisc 1.30.010.

ive found a few scripts to use with the ollyscript plugin but i can only find for version 2xx and above... so they wont work :S

anyone got a clue what other tricks i could try?

It seems that you're using a mallet to hammer in a tack here. Unless you're just reversing the program to learn, there's a simpler way of solving your problem. All you need to do here is create an .iso image of your disc and then mount the image to your hard drive. You can use program like Alcohol 120 or PowerISO to do this. Some games will work with this and others won't but it's worth the effort to find out. If you still want to reverse the program that's cool, but at least you'll be able to play the game without the racket from your cd drive in the mean time.

yeah i know ^^, just wanted to try and make it no-cd crack..
kinda fun if i just get it working lol

I hear that. Nothing better than experiencing that AHA! moment. And then reaping the rewards of course. Gl.

^^, ima try a bit more

Is there a .ICD file in the same directory as the game executable you are attempting to reverse?

heh i was about to ask the same thing, then saw this...


so i'd presume .icd there for sure...

Well then he can just use the appropriate version of Unsafedisc and *boom* NOcd created. Nifty little utility

no icd file there -.- ?...

edit:nvm,managed to get it cracked, thx for the help ppl

Could you share your findings/solution so that in the future when someone stumbles upon this thread they can learn something?

i just used the unsafedisc as rendari suggested ^^

So, then, you really were not interested in reversing it? When you couldn't get past the GetDriveType, then realized it had safedisk, did you not wonder why the GetDriveType patch didn't work? How did they know you had patched it?

he just needs resurection on:
>>I promise that I have read the FAQ and tried to use the Search to answer my question.

Um... this is a first. No, really.

I've seen people want to break CD checks BECAUSE they wanna play without a CD. Not because the CD makes a lot of noise.

Suggest you COPY all the files in the CD into the GAME installation folder.

Your CD should then be accessed a lot less (unless, you've tried and used the game installation option that says MINIMAL installation or somesuch)
