The 8BitDo Pro 2 in XInput BT mode (mode switch set to X) spoofs
Microsoft VID 0x045E / PID 0x02E0, identical to the Xbox One Wireless
Controller. RetroArch matches the existing Xbox One profile on VID+PID
(score 60), which maps Menu to BUTTON_R1 (103) — correct for the real
Xbox One's proprietary BT protocol, but wrong for 8BitDo which uses
HID-over-BT and sends BUTTON_START (108) for that button, causing Start
to be unresponsive.
This profile matches on device name ("8BitDo Pro 2", the BT advertised
name) in addition to VID+PID for a total score of 90, taking priority
over the Xbox One profile. The only mapping difference is
input_start_btn = "108" instead of "103". All other bindings are
identical to the Xbox One profile since 8BitDo faithfully emulates the
Xbox One HID report layout for every other button.

Also worth mentioning: controller vibration is now supported with BT XInput controllers in Android RA, DInput 8BitDo doesn't seem to be able to do vibration, necessitating the above. |

The 8BitDo Pro 2 in XInput BT mode (mode switch set to X) spoofs
Microsoft VID 0x045E / PID 0x02E0, identical to the Xbox One Wireless
Controller. RetroArch matches the existing Xbox One profile on VID+PID
alone (score 60), since the BT advertised name "8BitDo Pro 2" differs
from the Xbox One profile's input_device "Xbox Wireless Controller".
This causes incorrect button mapping throughout: the Xbox One profile
expects Microsoft's proprietary BT protocol keycodes, which differ from
the standard HID-over-BT keycodes 8BitDo actually sends for nearly every
button except A and B. Verified via pad tester.
This profile matches on device name in addition to VID+PID for a total
score of 90, taking priority over the Xbox One profile, and uses the
correct standard HID keycodes throughout.
