The best PS1 emulator now has better online multiplayer than most modern games
A community developer has dug into the incredible PS1 emulator Duckstation in order to add rollback netcode - which effectively means PS1 games now have better online multiplayer than most modern titles.
The developer, who goes by HeatXD, recently published this fork of Duckstation on GitHub (opens in new tab), and while you should "expect rough edges," it's already in a working state.

That's where rollback netcode comes in. The technical details of how it works are well beyond the scope of this article - I'd point you to
