- Put the controller into pairing mode first, then start Bluetooth discovery on Batocera. Use the Android D-input (Start + B) pairing mode.
- 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.
- Turn off the controller by holding down start.
- Restart Batocera.
- Turn on the controller by holding down start. BOOM! PROFIT!

East (SNES A) is B
South (SNES B) is A
North (SNES X) is Y
West (SNES Y) is X
Start is Start
Select is Mode (the button right under Start on M30)
D-pad as usual
Left shoulder is Z
Right shoulder is C
Left analog — hold any button to skip these
Left trigger is L
Right trigger is R
Left/Right stick press — hold any button to skip these
Hotkey — also Mode button (read the explanation about mode button functionality above).
Do this for all of your M30 controllers
For megadrive/saturn/32x/megacd add to system/batocera.conf to map A = A, B=B and C=C and two players with the same controller
For saturn (also similar A,B,C mapping idea as megadrive) but doesn't work properly, but it is only to play panzer dragon zwei, so it is not a problem.
