FFVI: Divergent Paths

Hi there. Two new bugs to report.

First of all, the lower half of the background is gone in the screens where you have to divide your party among two or three teams (battle of Narshe, Phoenix Cave, Kefka's Tower).
Personally, it's not a big deal because I know where to place the characters but for new players it might be a bit confusing.
(For the record I'm using Retroarch's Snes9x2010 core.)

The second bug is a bit more annoying.
I got around to playing Kefka's Tower. Party 2 and 3 got to the later part where they have to stand on the switches to open the center pathway.
But when I switched to party 1, I suddenly found myself in a map that seems to be the pub of Albrook, devoid of any NPC's.
Leo was the leader of party 1, as you can see on the photo I took. I'm not sure if that's related, or if this is just a coincidence.
