FFIV SRAM Issue|Technical Corner|Forum|SNES HUB

Just replaced the SRAM battery on my original copy of FFIV. The replacement went fine, I checked the polarity of the battery against an original cart, it should all be good as far as I can tell. 

However, when I leave Baron and try to save for the first time I encounter an odd glitch. The save slots are all a different color from the menu. All saves read empty and show glitched graphics instead of my party members. When I try to actually save it says it saved but the slot remains empty and nothing changes. Anyone have any ideas here? Does it seem likely that one of the chips is cooked or something? 

Everything else works fine, including the in game clock. No idea if thats relevant.
