My solution was way more complicated than the one for Hacking Forensics in the game (since it highly depended on just having one initial infection).

My solution[gist.github.com]: It uses almost all the lines, and depends on numbered labels (which are barely explained in-game and I didn't have to use in any other puzzle, neat!). Is the expected solution simpler?

I realise I never planned for a solution like this (based on bitsets) for the original puzzle, if this was an expected solution I would surely leave more registers to allow some more variables to be used and make things a bit easier :P.
