I don't know what ever happened to Netscape's version, but various homebrew attempts have been made.

One Linux on N64 project was discussed here a few years ago: https://news.ycombinator.com/item?id=25539319

There was a version of Mosaic in the SharkWire Online device, recently there have been some efforts to make that more usable without the SharkWire, though I don't think much is public yet, some discussion about the ROM here https://www.reddit.com/r/lostmedia/comments/1i2odym/update_f...

> each character is represented by a 3 degree angle of the analog stick

This humor is golden. Now I have even more reason to keep my stock sticks in working order.

They had me until the analog stick bit NGL

The Netscape thing isn't that far-fetched, though. Sega Saturn had PlanetWeb in 1996: https://segaretro.org/NetLink_Custom_Web_Browser

And I 'member the LinksBoks web browser on XBOX in the 2000s that had workable input via analog stick. Point the stick at one of the clusters of letters and press one of four colored face buttons: https://web.archive.org/web/20050903121908/http://ysbox.onli...

It's got busybox, we're in!

I found a video of a n64 port in action:

Immediately answered with a "what if you made a beowulf cluster of those!?" comment

The modem was an external add-on, there wasn't any special support for it built into the consoles. I think one reason why it wasn't a big success was that a lot of its appeal was being able to easily do stock trades and check your brokerage account from home, and the Japanese stock market started its decline in the early 90s. I don't think many people were excited to subscribe to a service whose main purpose was showing them how much money they were losing.

Interestingly, the JRA (Japanese horse racing association) continued accepting remote bets from Famicom modem users until 2015. Here's a video of someone placing a bet in 2008: https://www.youtube.com/watch?v=ks0JeyhZsR4
