Multi Button
The Ultimate-64 has one button on the side of the board, which is placed on the original position of
the power button.
This button is called the MultiButton, because it handles several functions.
User Interface
The Ultimate-64 provides a user friendly menu driven interface, which can be accessed by pressing
the multi button (power) briefly.
There are two modes in which this user interface can operate:
1. Freeze mode
2. Overlay mode
In Freeze mode, pressing the power button briefly will interrupt the currently running program on
the C=64 and show the menu. Leaving the menu will resume the C=64 gracefully. This mode of
operation works on both PAL and HDMI outputs.
In Overlay mode, pressing the power button briefly will show the menu in an overlayed area on the
screen. The C=64 will simply continue running, but the keyboard is switched over to the Ultimate
application, as long as this overlay screen is visible. Pressing run-stop in the file browser, or
pressing the power button again briefly will make the overlay disappear.
The user interface has three main functions:
1. File browser
2. Configuration of the Ultimate 64 (F2)
3. Tool menu (F5)
