It's not really a straight remake. It doesn't feature the exact full overworld map, and it has different dungeons, and it has a time limit. The Satellaview essentially let you play live games, and live sound was streamed, so they had CD quality audio, including voice acting. And things would happen like at a certain time, no matter where you were, certain effects would happen, and the live voices would announce it.
Because of the live stuff, the games could only be played when they were "broadcast." If you weren't there at the time, they were gone. The Zelda ones were broadcast in four parts, and you could miss a part, but if you did you'd never get it again. BS (Broadcast Satellaview) Zelda was broadcast twice, with different dungeons, so online you'll sometimes see these referred to as "Third Quest" and "Fourth Quest," but they're more different than that.
That said, since parts of these games were live, and the downloaded ROMs thus weren't the full games, they couldn't just be emulated. Autists spent like 20 years recreating the games based on VHS tapes and stuff. At first they were missing a lot, so actually they made other dungeon maps that are still floating around, and if you find very old downloads, you might find those, but they're fanmade. But after a very long time they finally made accurate romhacks that let you play the game just as it was, even with the sound and the time limits, but you can play whenever you want. They also let you get edited versions that remove or change the time limits, or add English subtitles, or even swap the voices for an English fandub. While normally I hate dubs, in this case you do want to be playing fast, and reading subtitles while playing might be awkward, so I did find the dub useful.
The two BS Zelda broadcasts based on Zelda I are very cool, but there is also a third one, called Ancient Stone Tablets, which is based on Link to the Past. It has a much more original story, which takes place during Link to the Past, and Zelda summons you to save Hyrule since he's away. But anyway you have four parts, each about an hour each (actually more like 50 minutes due to loading and cutscenes and stuff) where you have to do new dungeons and a few new overworld challenges. It's a similar concept to the first BS Zelda maps, but more expanded.
They also did broadcast regular Link to the Past over Satellaview, but that was just the regular game, with no special features. So you actually could just download and play whenever you wanted. But it's just the regular game.
Anyway the BS Zelda games are cool as hell, and especially by Ancient Stone Tablets, you can see the time mechanics that feel like early versions of ideas that would become more important in Majora's Mask.
There is also an Ancient Stone Tablets-esque semi-sequel to Super Mario Bros. USA that was only broadcast on Satellaview. Does anyone know if that's fully playable yet? That game seems cool as hell. There were also F-Zero tracks, basically DLC. And wasn't there a Fire Emblem game that was originally Satellaview but then got rereleased? (I don't know anything about Fire Emblem.)
