    Wondering if anyone knows any info on where I can buy the connector like the ones on the GameShark cartridges.

    I haven't been able to find the exact part, and several people have told me that it's a custom component.

    Having said that, I suspect that this one would work if you filed down the angled ends of the connector, since everything else seems to match. I haven't verified this, though.

    Awesome! I think that might be it but damn its a tad pricey, the pin counts looks like it matches too. Thanks.

    So I took my broken GS apart and looked at the components and the Connector but I can't figure out what the White SMD parts are, oh and the connector looks like the one Trimesh linked to as it does look like the sides are grounded.

    They look like capacitors - probably low value ceramics

    I was looking up alot of info and it might be a KEMET 1nf capacitor and I assume the 103 resistors are 1k?. Any idea what kind of crystal this is?

    103 will be 10K (10 + 3 zeros) - those caps appear to be the load caps for the xtal, so I would be very surprised if they were 1nF - probably more like 15pF. The xtal looks like it's the clock for that PIC, so it could be anything from 32kHz to about 16MHz depending on how the clock mode on the chip was set. If the PIC is still working, you should be able to monitor the signal on CLKOUT to find out what frequency it's running at.

    How can I do that? I have a multi meter available but no oscilloscope.

    So non of the markings on it help? well I found the values of the caps using my capacitance meter and they are :

    KE1 - 0.015nf
    3 Ceramic caps - 0.1uf
    2 Resistors - 10k

    Makes sense - 0.015nF = 15pF, which was exactly what I thought. It doesn't give any useful information about the xtal though, since I just had a look at the datasheet, and they specify 15pF load caps in most of the operating modes. Those axial lead cylindrical can xtals were originally used in 32.768kHz watch applications, but by the mid '90s they were being used at much higher frequencies, too.

    I think you will have to find someone with a scope or a frequency counter and check it that way - the best place to check looks like pin26 on the PIC, since that's the output of the oscillator buffer.

    Thanks alot for the info,I guess I will have to get me a cheap scope then since it will prove useful for other things in the future.
