I was looking at the typical Aladdin XT 2 Plus modchips that are still available/being produced for the Xbox a while ago, and I thought to myself that the wiring to permanently ground the BT pad seemed a little inelegant. I took a quick look at the traces on the PCB and lo and behold, they trace back to adjacent pins on the Lattice CPLD chip!
Going forward should I ever need to install another XT 2 Plus, I'll forego the wire and just bridge those two pins.
