Found a Nectaris GB enthusiast

for when you get around to the GB KISS(id imagine that a IR USB device would help emulation for those that can't afford to get it or to try and mitigate scalping) http://nectaris.tg-16.com/intro-nectaris-GB-KISS-LINK-FAQ-gameboy.html the full scans of the manual seem to be missing, the insert ones though are here http://nectaris.tg-16.com/gbim/insert1.jpg http://nectaris.tg-16.com/gbim/insert2.jpg you could try and contact him to see if he still has the manual scans, but i don't know how much luck you'll have the passion he displayed reminded me of you

Thanks for posting all of that information! I actually referenced that Nectaris site quite a bit while writing my upcoming book. It's a shame some of the pictures of the GB KISS LINK are so low-resolution though.

I still have my eye on quite a few DS accessories to work on. I've had most of the items on that list in my possession for a while (including the NTR-030, e.g. Hoshizora Navi). Still looking for the Bayer Digit though. Unfortunately, the DS is going to have to wait until I finish up with the rest of the GBA stuff. We're actually very close to having all of the officially licensed DMG/GBC/GBA accessories/peripherals/cartridges emulated in some form or another, so I want to see that goal taken care of first before doing more DS work. Unlicensed products aren't a priority at this time either, although I have my eye on them (such as the Shark MX, for instance).

Regardless, I appreciate your enthusiasm for exotic Game Boy/DS hardware! Feel free to post any more research you come across here. It's a slow process, but we're gradually preserving things.

Thank you for showing enthusiasm in obscure accessories too!

I also am excited in emulating or at least virtualizing (making a full Linux VM) for old Smart TVs.
