Yeah, I know we already have Kyledove's tiles and probably multiple other takes on DP's look in tile format, but I though someone might find this useful anyway- There's a bunch of actual tiles buried in DP's code that someone found. Here's the thread I found them on, and here's the tiles themselves. They're not really in any useable order and some components are missing (I don't see any mountain tiles in there besides the cave openings, for example), but if you ever wanted some authentic tiles from 3D-era Pokemon, here you go.
These were ripped by CytricAcid/Cyhuntastic, of course, not me. So credit him if you decide to use them.
