TECH Cassette Kensaki - NUS-you S Cassette Super Nintendo

The NUS software on the cart is designed to work ONLY on the special NUS Checker hardware system. While the physical flash cart can technically run on a standard SNES, the NUS test software programmed on it MUST be used in combination with the Checker hardware to use its functions. All those red Caution messages you see when booting the cart is errors where the program is trying to communicate with the special hardware and not receiving the responses it expects.

Standard controllers aren’t supported by the software at all, further proof that it’s not meant for regular systems. All user input goes through a special register instead. Apparently, the NUS Checker hardware has its own kind of controller (or more likely, has buttons or a keypad located on the front panel) that must be used to navigate the menus.

It’s possible to create fake input by using cheat codes to navigate through the menus. But there’s not much to explore or do as it’s not running on the correct system. As its name suggests, it just checks the hardware and vice versa and that’s about it
