Game Maker source code

Link please....

Here I go again writing ambiguously.
The source code for whatever game they're talking about, that Game Maker compiles, NOT the source code to Game Maker.

With that and the Game Maker documentation, someone could probably tediously recreate the game on a different platform like SDL.

I think with a lot of effort, someone could port the Game Maker source code to a reasonable language and make it run on the Pandora, but it wouldn't be easy, and probably not legal.

What I'm saying is the source files and graphics for the game under game maker (the .GMK) are available with a license that doesn't explicitly say it can't be reverse-engineered or ported to another language. Here's the license as written by the author of the game:

even if such holder has been advised of the possibility of such damages. Such
damages include, but are not limited to, loss of data or data being
rendered inaccurate.

Which, in my eyes, means it can be re-written for any platform or in any way as long as credit and the original license are present in the new game. Which sort of reminds me of the GPL. But getting back to my point, is it possible for someone to rewrite the code in a way that it isn't reliant on game maker?

Well, I decided to take a look at it.
The source is in some kind of Game Maker package file (.gmk), and the Spelunky site says you need Game Maker Pro to open it.

So someone else would have to do it, or at least copy the source out into text files. I'm not paying $25 for a fucking Windows source code reader.

This.

Is.

Hilarious.

But I digress.

Game maker uses it's own scripting language, and whether or not it would translate well over to a REAL programming language... I'm not sure.

Wikipedia's overview of the language is here, official documentation for the GML scripting language can be Found here

If someone were to considering taking this on, I'd be more than happy to tediously rip all of the assets from the game maker files \ You can copy each sprite individually as a PNG file, but there's no feature to export them all unless in some proprietary Game Maker format.)

Apparently there are several half-dead or on-going projects claiming to be able to open a GMK file and recompile it using JAVA to run multiplatform - but I haven't seen a single result from any of these yet. This is an awesome game, probably one of my favorite games ever, but it doesn't seem like it'll ever break out of game maker.
