Custom Atari 2600 test cart
03/17/2022 at 10:35 • 0 commentsI have developed a custom Atari 2600 test cartridge to allow me to test the features of the Wolf adapter. It makes possible to test a keyboard and a Joystick with booster grip at the same time.
It will read the state of DIFFICULTY switches being A for joystick and B for keyboard and enter one of the following modes:
Left: Joystick, Right: Joystick
Left: Joystick, Right: Keyboard
Left: Keyboard, Right: Joystick
Left: Keyboard, Right: Keyboard
It can test joysticks with omega booster. The button state is show using 2 methods: - The score counter shows the logic state of the TIA inputs (1/0) in the following order:
- The second method is graphical and consider the fire button active low while the thumb and trigger buttons are active high.
The keyboard is straightforward.
