Cheat Engine

Frantic Frigates (on kongregate dota com) is an action games that stores its money in 'double' format, or whatever you call it.

However, when I find the value and change it, it (the game) detects that I have changed it and a black screen pops up saying "Couldn't you have done this without cheating?"

OF COURSE I CAN! [s]however.....[/s]

There is a video on youtube that explains that this game uses some sort of cheat detection and then shuts the game off when id discovers you cheating, and gives you the bytes needed to disable it (which must be done at teh very beginning of the game (even before the 'Plenty of games' intro or whatever) which is done by using the speed hack).

SOOO, could someone explain to me how the cheat detection works since I already know how to disable it? (I can't post URLs)

Also, I want to know if there is a way around the cheat detection without actually changing the code for cheat detection. Such as changing the assembly code in such that when you get hit (lose life) you gain money and such.

The cheat detection most likely keeps an almost undetectable "copy" of the actual values.

In game values will always be changed with a function like:

changeVal(gold, -1000);
the function will also change the copy correctly.
if you just change the value, the game will check against the copy on the next frame and see that it was changed from the outside.

the so called copy might be the actualy value negated and multiplied or anything that is reversible.

I haven't looked in the code, this is just a guess.

Also, I'm gonna look for AoBs soon.

Can't open with Sothink 5.
The SOL is made of a single Object, I may not edit at this point.

Sorry can't help.

same for sothink 6.
Yogda opens it, but it's a pain to work in Yogda without a decompiler.

Right......so here are the Array of bytes that code for the cheat detection

30 D0 66 ?? ?? 76 2A 12 ?? 00 00 29 D0 66 ?? ?? D1

and when you change those guys to this:

47 D0 66 ?? ?? 76 2A 12 ?? 00 00 29 D0 66 ?? ?? D1

The cheat detection is apparently turned off and I can edit the double value for money. (must be done at begining of game quickly, which is why using speed hack helps).

I don't know what you guys are talking about Sothink and Yogda and all...

*sigh* wish I could hack like you guys! Where did you learn all this stuff from?

Well I learned C++ in school but only learned how to make simple command line programs. I've been reading tuts too...but C++ seems useless in hacking. Doesn't everything eventually come down to assembly since everything is written in hex?

non graphical c++ shows you the basics of syntax for most common languages.

C++ felt quite complicated to me though, with all the stadx.h or .io or whatever you had to put at the beginning. Assembly, though a lower level language seems simpler to me...

Well, I guess I don't know what I'm talkin' bout. I was looking at it selectively. Well, thanks for your help guys.
