Yes. Scrap the VB version. I just did a livestream where I attempted to refactor it. I couldn’t even make a dent in it before my wrists and shoulders started to hurt from repetitive actions. The only legit use of that code is being able to know how Phil loaded in save files and skins, and even then, those formats are slightly horrid when it comes to RAM usage. It’s better to just roll out your own save format and use that, and just use the old code to write a converter that allows you to upgrade to your new format.
Even then, don’t expect anyone to really want to play the game. ShiftOS is doomed as a codebase and a brand. Its reputation is so tainted that no matter how hard you try to recover it, it won’t work out in the end and it’s just not worth the time and effort involved.
You’re better off doing what we did with The Peacenet, and designing your own game within the hacking/OS-sim genre, coming up with your own gameplay mechanics, and only borrowing small parts of ShiftOS’s gameplay (or lack-there-of) just to create a somewhat link between the two games. Don’t revive ShiftOS, don’t revive it as a codebase or a brand. Improve on what it did wrong (and what it did right), and make your own game out of it. Come up with your own idea that captures some of the charm you got from ShiftOS… but manages to not be ShiftOS. If you can do that, then you are a better game designer than I am.
