Documentation
First unnamed parameter specifies the bottom text. For maximum authenticity, start it with "10G - ". You can also CSS float it with the "float" parameter (set it to "left" or "right"; other values will be ignored by browsers due to being invalid).

As a bonus, if you happen to have the actual Xbox 360 system typeface installed, it'll use that. Otherwise, it looks best in Tahoma. The actual image used is this deviantART submission's preview, alpha-transparencied and de-texted by me.
