Notes:

• Pins 01-18 are on the label side (01 = leftmost)
• ROM /OE is logically (not CPU R/W) or CPU /ROMSEL
• ROM /CE is grounded in Aladdin Deck Enhancer 1.1 and driven by PIC16C54 in 2.0
• Single game cartridges wire ROM as: PRG A17 = $C000.3, PRG A16 = $C000.2, PRG A15 = $C000.1, PRG A14 = $C000.0
• Quattro cartridges wire ROM as: PRG A17 = $8000.3, PRG A16 = $8000.4, PRG A15 = $C000.1, PRG A14 = $C000.0
• All Aladdin Deck Enhancer games use vertical mirroring, as there is no mirroring control on this port
