Hardware 3dsxl cartridge slot schematics

3DSXL Cartridge slot!

I have a slight issue with this motherboard, the copper pads in 3 places have come away from the motherboard. I am looking for a way to somehow fix this ?
I have read of a couple of methods and thats finding a replacement copper soldering pads and epoxy them back onto the motherboard.
Another is to find the trace and solder directly onto that using some fly wire, problem is the trace are super small and i am not sure if i can see them.

I know that the pin connection is needed but i am unsure if the others are (the huge square, is there anything obvious in the photos that i am missing) does anyone have a schematics for this ?

Thanks again!

the cartidge slot pad just appears to be ground connection, so you may be able to just leave it or at worst just solder it to any ground spot, as for the card detection pin you will have to solder the leg to the via using small piece of wire or something, and the 3DS can survive without the big cart slot ground connection

Thanks for taking time to look at this!
I was thinking some fly wire to attach the small leg to the via? Or solder an old pin to the via somehow?
