Cool. I put Mystery Dungeon Red on my eLink for my trip down to LA and I think it's pretty cool. Though what's really amazing is how they managed to make overworlds for every single pokémon (pre-4th gen pokémon, mind you) using only 16 palettes.
I've going through the ROM in Tile Molester Alternate and writing down the offsets of various pokémon's OW data. I've ripped the Johto starters' OWs and I've already inserted them (after embarking on a very extensive palette project to make enough room to accommodate for the MD palettes). I'm trying to make my hack have more non-human NPCs because I feel like the official games didn't really have enough.
Let me know if you want any Pokémon OWs and I'll get them to you promptly^^
