Mechanized Attack have strange "bug"... There is some variables that changes while title screen switches to first demo sequence. One of these values (according to RAM initialization routine in FCEU) contain 0xFF. That value should be overwritten to PRG bank number, but it's reading starts earlier than it happens... So, MMC1 handle 0xFF as RESET command and bankswitching fails...

That bug don't occurs if memory initialized with zeroes or something but not 0x80 (at least in FCEU)... But Mednafen, for example, still uses the same initialization routine but not crashes there... I'm not sure about, but probably NMI ocurs earlier or later than needed? Can soumeone help to figure out?
