Hi again, everyone!
Me and my friend Sparkster1993 have done this thing which I'd call a "foreground tiles map", which isn't an image file, but an XML map for use with Tiled editor (
https://www.mapeditor.org ).
It can be exported to a variety of formats like CSV, JSON, JS, LUA and even GameMaker Room resource files, in order to convert it to actual game objects in any new game, fan-game or anything. I wonder if this can be hosted at VGMaps, does it make sense?
Here are the files:

I don't think we'll continue working on it though, as Nic said he's more keen on a MegaDrive port than the one I intended to make for current-gen consoles from scratch. Anyway, good luck to everyone!
