There was a game made a while ago called RoPW written in Game Maker language. He shut down the game about a year or two ago, but released an open source for the public to learn from. He blurred all the sprites so people couldn't steal them. I still own the original version, and I was trying to inject a code so that it would retrieve all the sprites. I am trying to replace this code:

Go on the game maker forums, I heard there is a program that someone posted that you can get all the sprites/music/etc off of the (I think .exe or GM6).

Nah, I think its for when your files get corrupted, I used to work with GM myself, and still do once in a good while.

I think I know why, you`re searching the stuff in CE right? well CE only picks up values (like numbers), that and text searches, did you try searching under 'Text'?

Yeah, I tried to search under text.
It just says 0 results found either way.

Well then I guess you just can`t edit it. Sorry mate.

Could you explain why?

Yeah because the function is not going to be in text where you can plainly see it. Only stuff like names of characters and things maybe.

The rest is encrypted from compilation or obfuscated.

Now if you find out what that string is in bytes you can do a byte search and maybe find it. Then alter the bytes.

But why not try using a hex editor?

Could you refer me to a good hex editor?

CE has a hex editor in it dosn`t it?

Hex Workshop is a well known one.
Then try to look for the bytes of that instruction.

Cheat Engine is a memory editor -- compiled code, let alone executing code, does not maintain the syntax / identifiers used in high level languags.

You're better off trying to compile a new executable that uses the old files containing the sprites with a function to dump the desired data.
