Hey, this is nice. Glad to see that someone has come up with something that works, is free, and easy to use.

I'll be certain to use this in the future, unless someone manages to get past it by then—which is possible, however unlikely it might be.

This is pretty cool! I've been looking for something like this for quite a while!
Thanks for taking the time to do this!


Also, to help out, I made another skin (security themed)
Here's what it looks like:

Why this reminds me of Phoenix Wright? XD

soon the hackers will make an anti anti decompiler XD

Oh it is possible.
all protection methods are crackable.
this one is just the hardest gm protection to crack atm.

Nice job Score.

It's not really that hard, other than cracking the encryption. Not that I would know how to crack it as of now, I just know how it works, which would help.

Well, even if it is simple to do, decrypting and re-encrypting a Game Maker file, you must admit it's very useful. I don't really worry much about game sbeing decompiled though, as if it is a game posted on the GMC or YYG, you have proof it was yours first.

Great job!

This is great! Just one question,
will this at all effect the games performance? As in, cause any errors/bugs for the game when it runs?

It will not slow down the game, and it does not cause any errors or bugs in the game as far as I'm aware (tried to keep interference minimal, and added some checks to all altered functions).

I think this might have messed up my game.
I created an exe with Game Maker, ran it, worked out fine.
I patched the exe with your program, ran it, it loads for a second and then quits. Someone else
that downloaded my game is having this problem too. I am running Vista btw.


EDIT:
Yes it's definitely the patch I put on the game that's causing it to close.
Is there anyway to make it so my game still runs while using the patch?

EDIT 2:
Ah! Thank you it works now!!

After discussing this on MSN, we came to the conclusion that it was a debug checking script (updated first post now to warn against this) that was causing the problem.
No debug forcers work on the anti-decompiler, but debug checkers will almost always detect debug mode (as the data is overwritten with random values).

Nawwww man. . . now where do I get my code from??

When I send my antidecompiled game to my friend, friend's computer says it has Packed.Win.PePatch.dk virus.

It's normal anti virus giving false positives on those kinds of things, so there is no need to worry.

The anti-decompiler is not a very large modification to the game, so I'd not be very surprised if it did this for every Game Maker game.

No, it doesn't show alert on normal GM game, like it shows with antidecompiled game. Look at this screenshot: http://img161.images...406/antidec.png
Also, someone would like to choose how game will be antidecompiled, like in obfuscator you can choose what things the program will do.

I'm at a complete loss as to what options I could put, and why anyone would want to remove functionality when it does not affect the game after loading.

Edit: If only 3 antivirus programs detect a virus, and 2 detect a possible variant of a packing (not virus) algorithm, (leaving only 1 antivirus detecting a virus) then usually the file is safe.

I didn't talk about the safety of file, but it will be very annoying when antivirus alerts every time you even enter the folder or run the game. You should change something in packing algorithm.
