and another by some guy named Jackson:

I have closely inspected Jackson's images on different forums and I can pinpoint where to solder
most of the wires, but I have a few blindspots for the DMG buttons (Where the sp buttons are wired to).
Has anyone completed this project and doesn't mind lending a few tips?

Jackson's seems more complicated since you have to solder wire to every pin to the cart port, but
at least you can see where the wires are supposed to go. The rest appears to be easy to figure out
after studying closely.

I've got the DMG board drawn off to where I need to make the cut,
I can see the following places I need to solder wire:
-L/R shoulder buttons
-Start/Select buttons (SP only)
-D_Pad, A&B buttons (SP only)
-DMG Speaker to SP audio pins/flats

I cannot see the following:
-DMG D-Pad, Start/Select, A&B buttons to SP buttons circuits/pins?
-Volume dial from SP to DMG
-Power switch from SP to DMG and Rechargeable battery

If anyone can help, it would be greatly appreciated.
