Does an entry have to actually run on an old system, or is it okay to make a game in a modern engine with the look & feel of an old machine?
i think its ok but you shouldn't get any "How exotic and/or old the platform is?" Points in rating.
Sorry if the english is bad i am not native english speaker.
So we need to provide a binary which can actually run on the chosen platform. Then I'm out, because I can't do that. I was going to use Unity to mimic an old portable device. That's a shame because I like the theme.
