A question about the compo

Senbir2-Small.gif I made a game about computers for this Ludum Dare. Specifically, virtual computers. With processors. And RAM. And so on. The "Running out of space" gimmick is that you're running out of RAM/disk-space - your computer only has 128 bytes (32 memory addresses of 32 bits each) of RAM, and your drive isn't much better at 1024 bytes (256 memory addresses).

That's not really the main reason I'm posting this, though. I'm wondering if it's compo-legal. I've been toying around with the actual ideas for the processor architecture the game implements for a few days before Ludum Dare, as well as a Unity-compatible implementation of it. I don't THINK it'd fall foul of the rules, due to the clause "You’re free to start with any base-code you may have.", but I'm not 100% certain.

Thoughts, jammers?
