Select a channel from the dropdowns below, then click the emulator button to start up the virtual NABU. If, after you've started the emulator, you want to try a different channel, simply choose it and click the "Reset" button. (Sometimes the emulator may get stuck; if this happens, simply refresh the page.)
"Joystick Keys" allow joystick #1 to be controlled with the arrow keys and spacebar. It's turned on by default. If you find yourself unable to type spaces, you probably have it enabled and should toggle it off. A small joystick icon will appear in the bottom-left of the NABU screen when this feature is in use.
The "GO" key is the same as the "Enter" key - when a program tells you to press "GO", press Enter.
