This is great, I love the links to where they are available and videos, I might try one or two of these out!

Me neither, but I have only vague idea about these handhelds anyways.

Wow you really have an obscure list. Another one I never heard of before

Chips Challenge - https://store.steampowered.com/app/346850/Chips_Challenge_1/

So along comes this colour handheld called the Atari Lynx. Move over Gameboy, time to get schooled. Well, Nintendo weathered that storm pretty easy and the Lynx faded into oblivion only to make guest appearances on E-Bay. But the Lynx produced 2 of my favourite games ever and one was so good you can even buy it right here on Steam. Chip’s Challenge was a simple puzzle game with some fantastic level design. It uses some very simple mechanics and builds on them until you are tackling insanely sized levels of complexity.
