@TheoAllen I'd like to; believe me. The sad truth is that there already aren't enough hours in the day for my existing to-do list. Additionally, your reference would require a near-complete rewrite of my code. I'm not specifically against that (code is old; I'm often amazed it's functional), but again, there's that time-in-the-day thing. Not enough of it. The main reason I did things as I did was I found it easier to process a tileset in individual parts. Also, I didn't want it usable by folks that don't actually have RPG Maker in any given set of tiles, like the XP ones. There are potentially legal ramifications otherwise. I do want to rework things one day, but there's a lot to consider, and ease of use and legal access to materials is near the top of my list.
