Which pin is "1"?

Post by dustytrash »

Hey guys, I'm trying to create a SNES cart reader and I've found a diagram showing which pins are used for what.

I'm wondering how to know which pin is "1" and which is "62"?

I have a Cartridge and a 62pin connector.

You can usually find the numbers printed in the cartridge's PCB itself.

For the 4 games I took apart, Seiken Densetsu 3, Mario Paint, The Jungle Book, and Final Fantasy Mystic Quest, pin pads 1 and 62 were not present.

https://wiki.superfamicom.org/schematic ... nd-pinouts states:
Many carts connect only to pins 5-27 and 36-58, as the remaining pins are mainly useful only if the cart contains special chips.
I did find pads who's numbers are multiplies of 5 marked though:
