The simulator UI supports English and Chinese for now. In a desktop browser, you may use mouse to toggle or click the switches on the panel directly.

There is a DEBUG tab where you can check the internal status of the simulated 8080 CPU, or the contents of the simulator's memory.

The simulator works fine with modern mobile browsers, except that it is a bit challenging to touch a single switch on the panel on a mobile screen. Although, the helper switch buttons below the panel can be used as an alternative solution.
