Nice. I'm glad you're playing that again.
I honestly did a few improvements even from then. Mostly later game stuff, but still. The final dungeon in particular recieves a rather large revamp. I've mapped a bunch for it, and I'm still not done with even the mapping. The scripting has barely begun, though.
There's also an event after Kanto I'm working on, too, but I've been rather lazy on that, too.
