pin-out on the serial port / neogeo cable thing?

[Macabre]

So I was successful at making a really cool sd card adapter out of a vmu shell, but now I'm making one that plugs into the serial port via my neo geo pocket cable thingy.

Upon cracking the shell on this thing, it has like 12 wires (starting from one side, #1 is red, ending in a brown #12). The sd adapter only needs 7 wires, and the serial port only has 10 pins to solder to...

Anyone know the pin out on this neo geo adapter thing? I don't know how to use a multi-meter very well, and not too sure how I could use it to test this.

Turns out using an ancient multimeter with a broken selection knob tends to make you not be testing continuity when you think you are. I guess I'll have to finally get a new one.
