You may be asking yourself what homebrew games are. There are homebrew games made for the original Xbox, mostly PC ports, expanding the Xbox gaming library much more. In addition, ROMs are much more often hacked, an advantage to the numerous Emulators on the Xbox. Hacked ROMs could consist of slight graphic changes or entire new games. Below is an example of a hacked ROM "Super Mario World Redrawn" by Icegoom, the only change is redrawn graphics/sprites.
