AWESOME. I need to ask you, though; does it fit onto a single Graphics Bank? If not, that's alright, I can tweak it to make it work I suppose, but it's good to know ahead of time...
Dude. If you can make it fit onto a single Graphics Bank, I'll need to do something seriously special for you. GOD that would rule.
Edit: Oh, and you might already know this, but many of the tiles in the screenshot are flipped horizontally and/or vertically, so you can save tons of room by only including the non-flipped versions, since LM can flip them at will. It's sometimes tricky to avoid getting copies of the same tile, but it's always worth it in complex tilesheets like this.
High on life is the best high.
