Where Politics And Video Games Collide

@Soroki: In both the PC and the PS2 game, it's been confirmed and reconfirmed that the content was already on the disc. As Timson notes, PS2 disc images cannot be altered to include new content, so the content's existence on the PS2 disc is solid proof.

Before the game went into final production, Rockstar decided not to include the Hot Coffee content in the release build of the game. Rather than removing the content directly (which, in retrospect, would have been a good idea), the programming team flipped a few bits around in the code to prevent the conditions for accessing the content from ever being satisfied if the game were played as intended. For all practical purposes, the content was locked, it would never be seen, and the problem was solved.

However, modders don't just play games through normal means - they use various tools and methods (the details of which I won't go into) to look at how in-game content is encoded, make their own content either by (a) re-arranging existing parts in the game, such as custom levels and gametypes, or (b) writing new objects of their own, such as custom textures, weapons, or items. Patrick happened to be the first modder to notice the Hot Coffee content while examining the game, and as such, is credited with discovering it. Let's be honest - if he didn't find it, someone else would have eventually. Bravo for being #1, though.

So before you fire off accusations that modders make content and lie about its origins, do a little research to understand how things work. Because when you don't know what you're talking about, you just make an ass of yourself.
