This is a little strange, the ROM appears to be a standard SOP44 with reverse pinout but the
address lines are shifted one pin out of position compared to industry-standard pinouts.
The actual part number doesn't exist on the Macronix web site, even though they have datasheets for
everything else! So it's probably a custom design for Sammy and top-secret!
The size is assumed to be 1MBit and is 8-bit (D0-D7 only). The pinout appears to be this.....
