I searched everywhere for a completely merged RTP tileset and had great difficulty finding one. I made one, and I thought it'd be a good idea to stick it here for others to use.

Ah, this ought to save some people the trouble, Nice Job. :)
The unfortunate thing about relying on a really big tileset like this is that usually you have to go in and set all the passabilities, priorities, counter & bush tiles yourself. And in the end, you're still limited to 7 autotiles. Plus mapping is painfully slow when you have such a big tileset to search through.
While it's nice and convenient to have any tile there that you need, I wonder if it's more trouble than it's worth. If I need 3 new tiles on a tileset, it's nothing to jump into GIMP and copy them from one tileset to another.
Not bagging you. I also thought it'd be a great idea, once ;)
I bet you could just copy/paste the tileset after you set all the passabilities and then just swap out the autotiles. That solves that problem.
