Here's the process:

fdisk -l raspberry_pi.img

Which gives the output below. Note the sector size in bytes (512 in this case; see line 2 below) and the Start sector of the partition (94208 for the Linux partition; see the last line below).

Disk raspberry_pi.img: 7.3 GiB, 7826571264 bytes, 15286272 sectors
Units: sectors of 1 * 512 = 512 bytes

1. Put the controller into pairing mode first, then start Bluetooth discovery on Batocera. Use the Android D-input (Start + B) pairing mode.
2. After pairing it, it will likely go kinda crazy. Down doesn't work, and it keeps scrolling to the side, etc. Take a deep breath. We can fix this.
3. Turn off the controller by holding down start.
4. Restart Batocera.
5. Turn on the controller by holding down start. BOOM! PROFIT!

Add on $HOME/.xprofile to autoload on boot:

xrandr --newmode "5120x1440_59.97" 292.75  5120 5360 5888 6656  1440 1443 1453 1468 +hsync +vsync
xrandr --addmode HDMI-2 5120x1440_59.97
xrandr --output HDMI-2 --mode 5120x1440_59.97
