INSTRUCTIONS FOR PLAYING THE NEO GEO POCKET IN BROWSER:
The emulation will always boot with a blank white screen. Press the F1 key to 'power on' the system. Because there is no NVRAM setting, you will be asked to set the locale, time, date, and color settings. Simply press the CONTROL key until the system boots to the Neo-Geo System Logo. After the logo appears, the cartridge will boot normally.
Movement for up, down, left and right are done using the ARROW KEYS. Buttons A and B and CONTROL and ALT/OPTION. The Option key is 5. Pressing the F1 key after the system has booted will cause a quick reset without the requirement to do system settings again, until the browser window is closed.
