Beware ! Pinouts found elsewhere have /ROMOE and 4MB swapped, it's an error on the original schematics. /ROMOE is on pin 33 bottom, 4MB is on pin 34 bottom.
See Signal names for the description of each pin.
SLOTCS goes low when the slot is used. On multi-slot boards, the signals come from NEO-F0 SLOT0~5. On one slot boards, it's tied to SYSTEMB. The System ROM was written to ensure the signal is asserted when it does the slot check.
SLOTCS is used on multiplayer link capable games, trapping the HD6301 into an idle loop when high.
