Installation complete
Street Fighter II is ready to fight
Open the extension from Chrome’s toolbar. The original Champion Edition arcade game is the default mode and all code required to play is packaged inside the extension.
To start: hold 5 briefly to insert a coin, hold 1 briefly to start player one, then choose a fighter with the arrow and attack keys. Arcade mode restores keyboard focus automatically.
Getting started
- Pin Street Fighter II from Chrome’s Extensions menu for quick access.
- Open the popup; Arcade mode is selected by default.
- Hold 5 to insert a coin, then hold 1 to start player one.
- Use arrows to move and Z X A S Q E for the six arcade attacks.

Arcade and Training
Select Arcade for the original CPS-1 game or Training for the local mini-game. Restart follows the selected mode, and Favorite remains session-only without storing data.

Verified keyboard controls
Arrows: move, jump, crouch Z X A S Q E: attacks 1–6 5: coin 1: start
The in-extension Guide repeats the complete mapping and separates the Training Round controls from the original arcade controls.
