Unlike AES cartridges, the sprite graphics aren't pre-serialized by a NEO-ZMC2 or PRO-CT0 chip. The complete C ROM data bus is exposed to the cartridge edge, it's then decoded by the chip included on the board.

Since NEO-ZMC2 isn't present, NEO-ZMC is used to multiplex the ADPCM-A and ADPCM-B data accesses to the V ROMs.

The cartridge connector has 2*2*60 (240) pins. See pinouts.
