Xbox 360 is too demanding for in-browser play, so it runs through Xenia — a free, open-source desktop emulator. Here's the whole setup.
Use the button above — it always grabs the current Windows build. Format: Zip (portable).
Unzip anywhere — no install needed.
Xenia loads these file types: .iso.xex. We don't provide games — use discs/cartridges you own and dump them yourself.
BIOS: No BIOS needed.
Run xenia_canary.exe, then drag your game onto the window (or File ▸ Open).
Keyboard works; an Xbox or compatible gamepad is best.
