Notes in $029C and $02BC:
- When idle or standing in level icon or walking down he the first 4 slots are used by Yoshi and the last 4 slots are used by the current player.
- When the player is walking to left, right or up he uses the first 4 slots and yoshi uses the last 4 slots.
I still need to find some slots that are used by some other overworld sprites. I will edit this post when I found these (or someone else does it).
