Sorry. Im not sure what would make it a good or bad port. Im not familiar with what the differences would be.

It was originally released on N64 and the Switch Online N64 mode seems fine. It feels like the original game.

Honestly, its probably a good thing they canceled it. They were going to butcher that perfect game.

But also FYI, Perfect Dark is available on Nintendo Switch Online as a Nintendo 64 +17 Mature title, along with Turok and Turok 2
