Has anyone tried reverse engineering anything? (I mean from disassembly, not from guessing what it does after output)
I've gone and grabbed the encryption algorithm from some unsuspecting GM DLLs, and I've also been reversing for other means - but most GM security DLLs can be cracked with a simple XOR EAX,EAX / INC EAX / RETN XX (that number varies).
The hardest thing to reverse-engineer, IMO, is any delphi program.

Illegal. This should be locked.
REVERSE ENGINEERING IS ILLEGAL.

No, it's not illegal. Maybe in China it is.

It is in the USA. It goes against Copyright Laws(I think).

Wrong.
(...) reverse engineering of software is protected in the U.S. by the fair use exception in copyright law.
(I don't really think it's illegal in China either.)

Wait, if that's true, then does that mean we can decompile Wii Games legally?
-
You just can't redistribute them once you have. Or redistribute them at all, for that matter.
-
Or gain profit from the results, direct or indirect, of that decompilation (like selling mods with the encryption key embedded).

Thing is, though decompiling GM7 games is illegal according to YYG.

Grammar fail.

That'd still be redistribution. I'm pretty sure you can lay a hat on the street and have people put money in it while you reverse engineer something.
And Retro, they say a lot of things. It's so people feel a tad safer using something with no walls.

Whether EULAs legally stand isn't clear. In some countries it may be forbidden to impose EULAs at all, while in others, certain clauses may be unfair and therefore invalid. Restricting your right to fair use is probably an unfair clause.
Actually, "decompiling" Game Maker games doesn't count as decompilation at all (except for the runner): the data is there, just not organised in an accessible form.

I must try that :D
Game_Boy, you're inspiring me to write a decompiler :-\ I've already written 3 different methods of debug forcing.

I bet I could just take a Game Maker game and run it through 7-zip to get a GMK.
EDIT: Also, FYI Game Maker is made in Delphi. ^_^

No, it's not that simple. But yes, it's written in Delphi.
The game is loaded from the spare, unused bytes at the end of the file.

I know, but I was trying to make a point of how insecure Game Maker games are.

And you sucked seeds! (Succeeds*)
