User submitted screenshots now display the system of the game right before the name of the game within the url. Example:

Before:
Super%20Mario%20Bros_Sep10%2016_01_52.png

After:
NES--Super%20Mario%20Bros_Sep10%2016_01_52.png

This may seem like an unimportant thing to mention but here's why I did this.

Before, when you take a screenshot and go to retrieve it, all of the screenshots taken on games with the same name would appear on the same screenshot retrieval page. So for example, if you took a screenshot of 'Pac-Man' for the NES, Atari 2600 and Game Gear but when to retrieve the screenshot on the NES version of the game, screenshots for all 3 versions would appear on that page. This is because the screenshots don't have the system name in them so the screenshot retrieval page can only find the screenshot based on name rather than both name and system.

Now that the screenshots contain the system name as well, I'll eventually be able to make it so the screenshot retrieval page only shows screenshots that match both the game and system. Now I can't do it now since all screenshots taken before this update wouldn't be retrievable but 6-12 months from now, I'll make it so that only these screenshots can be retrieved (which would also make it so screenshots taken before 9/10/2012 couldn't be retrieved anymore, which is why I'm waiting a while before making this update to the screenshot retrieval page).

There actually have been quite a few people who have submitted the wrong screenshot to the wrong game, so this update will help to make sure that the user submitted screenshots belong to the game that they're submitted to. This update also applies to high score submission and speed runs.
