(I don't imagine there'll be many takers, but I didn't want to derail the SNES discussion in the general topic) Sega Retro has pretty much every Sega-related game documented (bar some really obscure arcade machines I can barely prove exist(ed)), but we're not very good at game demos. We've had a work-in-progress list for years, and I've started tackling a few properly in recent days. Demos accounted for: List of Mega-CD demo discs List of Saturn demo discs List of Dreamcast demo discs Demos not done (yet): Sega Retro:Todo/Demos (only tackling Mega-CD, Saturn and Dreamcast today but obviously they all need doing) I'm running into problems with the discs that are left: a) Many haven't been dumped, or are hiding on the internet b) Nobody seems to know what the contents are. Most of the Saturn's library never left Japan, so knowledge is generally thin on the ground c) I don't know what to name half of these - those Mega Power and Sega Pro CD discs in particular need their own pages, but I don't know if "Mickey Mania (Mega-CD demo)" is sufficient (or maybe it is?). I also don't know where some of these discs came from, and while I'm pretty sure I've verified all of these exist in the past, we haven't got scans and many photos are crap. And for the most part, the pages that do exist are little more than "this demo is a thing". Also note that some of the discs on that page... aren't demos at all. Other sites grouped them as such, but I don't know what a "Seaman Esa Disc" or a "Sabai Net" is. Do you?
