Also, I have a question for anyone that might be knowledgeable in the topic: What purpose does region coding serve?
Region coding exists so a product sold in one market(North America), cannot be exported to a second market (Europe). This is to allow companies to stagger releases. I'm not sure why they would do such a thing, but I'm fairly certain its so they can eventually go back to openly owning slaves like they have for 99.9% of world history.
I can give a little more info here, too. Different markets pay different amounts for different goods. Look at Region 5 for example...that's Russia, India, Africa, basically all the places that really don't have $20 to drop on a game.
Publishers have the right to charge what the market will bear. In the US it might be $20, in Russia it might be $2. Hey, there's still money to be made. In any case they charge a reasonable price in the US to recoup their costs, and then they have a secondary market too. Cool! If they charged the same amount across the globe, it would either be high enough that Russia could never buy it, or so low that they couldn't make back all the costs of development.
And...if it wasn't for region codes, some jackass in Russia would buy a thousand copies for $2 each, sell them to a buddy in the USA for $7 each, who would then put 'em on the shelves for $15, generating a huge profit from the primary market for the middle-man but very little for the actual publisher/developer.
In short, region codes are what ALLOW publishers to sell in cheap markets. They reduce piracy in secondary markets by the simple virtue of allowing people to buy the product at all. And then, they reduce piracy in primary markets because there's less spill-over from piracy in the secondary market!
Sure, people devoted enough to know how to change their drive's region code won't be stopped, but face it, someone that smart who wants your product for free is going to get it for free no matter what you do.
I think the region code system is an altogether good thing...except that Australia should have been moved to either region 1 or 2. As it stands now, Australia gets the same region code as Mexico, which sucks for Australia because their region gets products pretty late. But there's nothing sinister going on, and region codes are GOOD for consumers in secondary markets.
