Are you sure about that? The black there is part of the foreground because otherwise you'd see the actual background. Just casually looking through the pattern tables in Gens+ (which means I'm not looking at them as mapped, however) I don't see tiles for his right hand. Also, on the pallet issue, I'm thinking it might be best to use 8-bit palletized images (would be be useful to use separate 8-bit alpha masks?). That way, instead of storing multiple images for such cases, you can store the images to replace the tiles, and have multiple 256-color pallets to replace the original 16-color MD pallets. This would allow seamless support for ALL such pallet cycling in the game, and if you chose to support alpha images then you could have REAL transparent waterfalls and CPZ tubes as opposed to faked ones.
