Looking for photos of PAL Cx4 PCB

Ever since I first traced out the Cx4 pinout, I've been stuck wondering about the function of pins 74 and 75. One idea that came up was a PAL/NTSC switch, and though that doesn't seem to be incredibly likely, I'd still be interested in getting ahold of a PCB photo for a PAL MMX2 or MMX3 so I can see if they differ from the NTSC PCB, especially with respect to these pins (you can see in the photo they're all connected together to the same ground fill, I believe the MMX2 PCB has the bottom pin connected to a separate trace which connects back via a jumper instead, but still all 3 pins are shorted together). If anybody has one of these games they'd be willing to open up for science (no carts need be harmed in this endeavor, I just need photos ), I'd greatly appreciate it.

If you befriend a dentist or vet, you can get an X-ray of the device and see if the pins are wire bonded to anything at all...

Wire bond wires are usually 50 gauge=1mil=25µm, so magnification might be necessary.

Ooooo, actually my school has dental hygeine and medical imaging programs, both of which have to Xray random non-living objects as part of their coursework. Might have to ask around...
