I'm pretty sure that there was at least one newer browser for the Saturn Netlink, I belive that the major new feature it had was supporting frames. I was able to actually play a few sound files I found online with the Netlink.
The Netlink was my first access to the internet, which I used for years until I got a Dreamcast which I surfed with for about a year until I finally got my first computer.
Yeah, you could either get the newer version by booting the original and then upgrading from Planet Web's site every time you used it (makes an already slow system even slower) or by getting it on a CD from Planet Web. It was definitely better than the original, but probably wouldn't work with %90 of today's websites.
Does anyone know what browser was used in Japan, if any? The Netlink was marketed there as XBand, and I have the hardware, as well as some of the software, but I'm not sure I ever saw an actual Japanese web browser for Saturn before.
BTW, the only web browser on a console I can see using these days is Opera on Wii simply because of all the time I've pissed away watching Youtube on the Wii. Something about the Wiimote and Youtube...they just go perfectly together.
