So a friend of mine requested to remake and map Sinnoh in 2D and I was trying but stopped for a while, and I stop and start now and then.
I figured it was pointless keeping them to myself as some of the public desperately ask for such tiles, and if I didnt release them, someone else would do it and render my work useless.
For an example of how they work for real, here's a Work in Progress image of Sinnoh so far.
It has a lot of placeholder tiles.
Oh and please dont ask me what tile goes where, or how to hack something, or to put them in a tileset. Sorry.
