I have a custom CPU emulator, with 44 instructions (opcodes), and I would like to challenge you guys to code a better kernel for it (current one is a simple command interpreter with 3 commands: HELP, EXEC and QUIT). Can I?

  • \$\begingroup\$ @WilliamFernandes Yeah. It will most like be removed here, so the sandbox is your best bet. Goodluck! \$\endgroup\$

Sure! That's sounds perfectly fine. You might want to post a draft in the sandbox for feedback, first.

You'll need a concise, but detailed description of what the program should do. And probably some example inputs and outputs.

And you'll also need an objective winning criterion. (Something better than 'better', like shortest or fastest)
