[BUG] Seems there is something wrong with 8bitDo gamepads in 11.5

[dganzella]

hello! I just started development with Love2D and got to a issue using my old 8bitdo Zero bluetooth gamepad in macOSX.

In Love2D 11.5, this is the data I get:

name 8Bitdo Zero GamePad
GUID 05006f42ac050000020000004f066d02
Mapping: 05006f42ac050000020000004f066d02,*,a:b0,b:b1,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b6,leftshoulder:b4,rightshoulder:b5,
x:b2,y:b3,platform:Mac OS X,

-- Not only the GUID is different from what seems to be the actual GUID provided https://github.com/mdqinc/SDL_GameControllerDB , but also the mapping is wrong.

but not only that -- the map is unfixable because a single button is lighting up multiple inputs. For example, pressing A in the controller lights up b0, b1, b2 and b3

in 11.4, this is what I get:

name 8Bitdo Zero GamePad
GUID 03000000a00500003232000009010000
Mapping: 03000000a00500003232000009010000,8BitDo Zero Gamepad,a:b0,b:b1,back:b10,dpdown:+a1,dpleft:-a0,dpright:+a0,dpup:-a1,leftshoulder:b6,rightshoulder:b7,start:b11,x:b3,y:b4,hint:SDL_GAMECONTROLLER_USE_BUTTON_LABELS:=1,platform:Mac OS X,platform:Mac OS X

the GUID seems to be the correct one and the mapping works perfectly.

so I'm guessing there is a bug in 11.5, or maybe my 8bitdo zero is no longer supported (its an old controlelr, from like 2017 I think)

I tried copying the mapping from 11.4 to 11.5 but no dice.

Thank you!!

Do you have any way to test on another platform? Possibly, a macOS-specific bug in SDL?

Controllers from 2017 are not that old, and should still be supported.

I do not but I just ordered a 8bitdo lite 2 that arrives later this month. this is much newer, already USB C, I can test 11.4 vs 11.5 and check if this one works

You're not alone. 8bitdo gamepads seems to do some unexpected things which can require work-arounds on mac.

I don't personally own any of these gamepads, but this thread on the pyglet Discord server and commits below may be relevant:

• Broke things: pyglet/pyglet@ba71b7f
• Fixed them: https://github.com/pyglet/pyglet/pull/1297/files

Yes, it's a Python framework rather than Lua, but the weird behavior sounds very similar.

Do you have the same problem with a love 12 nightly build? Also when testing, avoid using third party GUID databases like the one you linked, to help narrow down where the issue is.
