Beginner’s House, Greenhorn’s Club, or whatever it’s called in your version of FF5, there are lots of generic NPCs that are available to mess with. These are notes for doing that.
On the first floor, there are 8 “old man” NPCs and this if what incrementing their NPC sprites by 1,2,3,4,5,6,7,8 respectively looks like.
I adding the value of the NPC number to the byte that controls its map sprite, to track the bytes easily after making a patch file. Here’s the guide the the above patch file creates.
Similar experiment upstairs, where there are 6 NPCs, numbers 9 thru 14.
