Played on the new NSO GameBoy emulator on Switch. Not as bad as I had been led to believe. I preferred the 3DS remake, but there's a certain simple charm to this one and it's different enough that it doesn't really feel like the same game.

Playing this through with all the modern comforts of save states on NSO made some of the unfair bosses and situations a little less frustrating, and using a map when I got lost was almost necessary at some points. However, you can see where they were going with this and it has some of the basic Metroid gameplay that's fleshed out in Super.
