The sudo16 is a fantasy 16 bit computer with a limited instruction set. How many instructions? That's for you to find out! The "game", if you will, is to reverse engineer the CPU and compete with your fellow hackers to create the coolest program in the limited system specifications (65,536 bytes of ROM, and 256 bytes of RAM).
However, if you get stuck, or you would rather get straight to development, you can reveal the instruction details below:
Note: Due to the minimum interval for setInterval, the fastest clock speed you can select is 250hz (4ms per instruction). However, you can switch to As Fast as Possible execution by entering MAX into the hertz box. However, due to the nature of javascript freezing the main thread, this method of execution may cause your program to crash (this causes the input example to, for example). This is not an issue for programs like hello world, that run through once, but may affect longer running programs. A fix is possible, but too much for this MVP. YMMV
