Just working notes.
Locations in the FF5 rom where character battle sprites are found
Hex value for 3 rows of tiles, 16 tiles across = $2772 (battle sprites are 48 tiles, 3 rows of 16)
PC location of 16-color field map palette = $1FFC00
Use chocolatebird to load and test (Debug Menu) all the sprites as animations (thanks, Birdulon)
Guide to explain this technique:
Excellent Mesen Palette Editing Tutorial by Cubear
Blue Mage beret needs less gold on Cheer pose, and more gold on casting poses
How did this happen??
