I could have tried to port, say, Actua Soccer to SCO Xenix, but I went with DOOM because the source is available, every detail is known, there’s a million different ports to learn from, there’s a reasonably clear separation of OS dependent and independent parts, everyone loves DOOM, it runs on any hardware, porting DOOM to platform X is almost a meme, … should I continue?

That being said, this is about the original, and official, commercial DOOM port decades ago.

One should read the readme's.

let people enjoy things.

Different strikes for different folks.

I love stuff like this. It’s computer history. It’s interesting from a technical perspective as well as being a snapshot of culture.

It's funny how you bother to look at the commit dates, but not the README and repository description
