Game data files

Overview
Many popular games use proprietary file formats to store their assets. These include custom image, sound and video formats and custom archive formats. There is no way that all of these can be enumerated here in some way or another. And as long as the games can still be run by an Emulator it's not that much of a deal. However, a lot of work has been put into deciphering, decrypting and hacking these files, and that work should be preserved.
