Hi there! I've been on-and-off working on TacOS for a few months, which follows some UNIX-derived concepts (exec/fork, unix-style VFS, etc) and is now able to run a port of Doom, with a fairly small amount of modifications, using my from-scratch libc. The performance is actually decent compared to what I expected. Very interested to hear your thoughts. Thank you!

What did you do make the project interactive enough so you don’t end up copying existing implementations?

I'm not too sure what you mean. I kinda just avoided looking at existed implementations because it's a bit more interesting to do it myself.
