Missing Systems
Despite my best web searching efforts I couldn't find anything that identified the last releases for the following failed
systems:
Pippin – The Apple/Bandai Pippin didn't last long and had a tiny library. Unfortunately there's no source that lists the release order for it's titles.
Amiga CD32 / Amiga CDTV – Both of these were flops in the US but enjoyed moderate success in Europe. Even the European release lists aren't documented especially well in the release date department though.
Neo Geo Pocket Color – I gotta think someone knows the answer for this one. The Neo Geo Pocket Color wasn't a commercial success in the US but has a decent cult following. Sooner or later someone will post a release list with dates.
Sega Pico – This is one of the most under-appreciated systems I can think of. It's a Sega Genesis with a touchpad, I find it to be a very innovative little system. Unfortunately there's no source I can find that lists when games were released for it. Being aimed at kids, it never developed the kind of internet following other obscure consoles have.
