Cheat Engine

I have thought of a way that would make it easier to find values. You can compare only with first search but it could be much more accurate if I could compare with different starting search values.

Where I am literally getting crazy about getting to change something, It’s not that I like that game, but I am already annoyed by not been able to cheat on it;

Ok, in that game “Diamond Dash” there are (green, red, yellow, blue and purple) gems, I have tried something that didn’t work. Objective, keep track of one block in the array of 9x10 board, the one in the top left. What I did was:
Make a first search when the gem was red (Unknown initial value), then go to the temp folder and copy MEMORY.FIRST of 150Mb. Then repeat the same with the other 4 gems, so I end up having 5 files of 150Mb.
From there, every time the gem changes, if the gem was blue, I replace the actual MEMORY.FIRST with the blue gem and do a (compare to first scan=Unchanged values), so I would be able to continuously make an (unchanged values) search knowing for sure there is no mistakes.
Actually, I thought this was a pretty good idea, but Cheat Engine Crashes when, after replacing the file, I do a “Next Scan”, the error is: “Scan error:thread 2:Stream read error”

Anyway this could be implemented?

It is already implemented
Do an unknown initial value scan when it is red
Then when it is blue do a changed value scan
Then click file->save scan results and name it blue
Then when it's yellow do a changed value scan again and save as yellow
Now when it turns blue or red you can do a compare against saved scan (e.g red=first, blue=blue) and then scan for unchanged

Thanks Dark Byte, it is exactly what I wanted. I am going to try it.

Thanks again


EDIT:
It is thronging me an error, I first did an initial Scan with (Value Type: All),
Second; changed Values scan and (File+Save Current scanresults=green),
Third; (Compare to saved scan=”select Green”).
Fourth I press button to next scan and I get this error:
Scan error:thread 0:Stream read error

Don’t know if it’s relevant but the saved scan results had 600.000 results.

Hmm, try a normal type like 4 byte. (especially when doing changed/unchanged scans)
I'll see if I can reproduce it with all

also, make sure your %temp% folder has enough diskspace (4GB at least)

This is cool, I knew you could compare to the first scan, but didn't know you could compare to saved scans, this will make finding things that are either on/off easier (ones that don't necessarily have a value of 1 and 0, but maybe two other values that they switch between, or like the gems in the example where its not a switch but you know that its going to be the same value, your just not sure what that value is exactly)

Unfortunately I was able to reproduce this issue though... I initially tried the All scan type, but with your advice tried 4 bytes, then tried byte, 2 bytes, 8 bytes, double... With the same result as the thread starter!

We get a "Scan error: thread1: Stream read error" comparing to the first scan working though, but selecting any other saved scan (even when I didn't give it a custom name, just the default) results in this error!

I do have more than 4 gigabytes free space too (around 10gb free to be exact), and even changed the temp folder in CE's settings to a folder on my 1TB external hard drive just to be sure there's enough free space, and the same results

Well hopefully you can reproduce the error, I'm running win 7 x64, even tried restarting CE to get fresh saved scan lists, and is there anything else important to note?

Thanks!

I was able to compare with a saved scan by reducing the results in less than 16000 results. If I have more than that, then I get the error. I have enough disk space and I have reinstalled Cheat Engine.

The compare to first scan allows any number, 150.000.000 of results and lets you compare. The saved scan allows you to save scan results of any quantity but will only let you compare if saved scan contains less than 16.000 results. I have checked in the folder for a saved scan result of 35.000.000 and the file is successfully created but needs to be reduced fewer than 16000.

Fixed in svn, it also affected first scan if you did a value scan as first scan so the addresslistfile would be an addresslist instead of a regionsave

Also, the exact amount it would cause a problem is when the addresslist is 81920 bytes or more. (20480 4 byte addresses, 10240 for all)

Thanks Dark Byte for fixing it, I haven't try it yet but I bealive it works now.

Regards.
