In Bizhawk, the graphics for the menu and intro are completely hosed.  Looks 
correct in FCEUX 2.2.2.

Gameplay seems to be fine.

broken in FCEUX newppu as well.
due to my limited understanding at the time of the necessity of emulating PPU 
disabled states. 
In this case, the sprite rendering was disabled, so the MMC5 A/B CHR selection 
for OBJ vs BG should not have been running; this was causing the game to read 
from the wrong CHR banks during initialization-time when reading its nametable 
entries from CHR.

fixed in r7517
