Does anybody have a confirmed pinout for the MaskROMs used on Cx4 PCB's? I've seen varying pinouts for the surface-mount MaskROMs depending on if they're 8-bit or 16-bit, and I can't seem to find any info on whether MMX2/MMX3 are 8 or 16 bit, or what the pinout is.
Edit: This page seems to indicate the ROM is 16-bit, but from some quick multimeter testing, there's no way that any of these pinouts match what I'm seeing
