I don't know if anyone here would be interested, but I've been looking into various links regarding game development for an outdated system or two. Examples of this include:
Gunlord for Neo Geo and Dreamcast.
Zaku for Atari Lynx (and every game that Brandon Cobb's Super Fighter Team has published.)
In other words, I wouldn't mind doing something like this, but am not much of a programmer. If anyone has any other examples of these types of games, I would like to see them.
