Xbox 360 was sold over a decade. Each version had specific hardware revisions so hackers creating these tools tend to refer to the hardware code names to as a way to identify which revision their hacks apply to.

The below list is from AI, but from a quick view is correct.

• Xenon (2005)

• Zephyr (2007)

• Falcon (2007)

• Opus (2008)

I expect the commenter has backed up their owned games to the hard drive so their kid doesn’t need to fiddle with discs damaging them, or has installed homebrew retro games. I expect all online functionality has been shut down anyway so it turns the console into an ad free offline gaming machine.

They are still outputting 720p, but the consoles are good value for kids.
