## What it is
A non-persistent, software-only hypervisor exploit for the Xbox 360 that runs unsigned code on the latest dashboard (17559) using a supported game and a USB stick. It enables homebrew execution without hardware modifications, but must be re-triggered after every reboot.

## Use cases
- run homebrew software on an Xbox 360 without hardware mods
- execute unsigned xex files on the latest dashboard
- softmod an Xbox 360 using a USB stick and a retail game
- boot custom payloads on Xbox 360 firmware 17559
- explore Xbox 360 hypervisor security for research

## When to choose
- you want to run homebrew on an Xbox 360 on dashboard 17559 without opening the console
- you own Rock Band Blitz (or a compatible game) and a USB stick
- you need a temporary, non-persistent hack that leaves no permanent modifications

## When to avoid
- you need a persistent hack that survives reboots
- your dashboard is older or newer than 17559
- you don't own one of the supported trigger games
- you want to modify the console hardware or flash its NAND
