Add 8BitDo Lite for Windows, Linux

[shavs]

This merge adds the 8BitDo Lite controller configuration for Windows and Linux devices.

This follows from libretro/ludo#342 (comment), and hopefully have a knock-on effect on glfw's controller map

Please let me know if there is anything further that I can provide

I should probably also mention that #470 relates

Thank you so much for the PR! Unfortunately both of these GUIDs are in invalid -- the Windows map is being handled by SDL's own HID driver (suffix 7801) and the Linux map is identical to the Xbox One Wireless Controller.

Most 8BitDo devices have unique fields even in Xbox spoofing mode that permit disambiguation on non-Windows platforms, but it seems like the Lite doesn't, at least on Linux. If you're able to get a unique GUID (not already in the DB) when wired, or in Switch mode, or are able to test further on Mac or Android please feel free to open another PR or follow up however suits you best!

Thanks again

OK, thanks!

I did have a look at the difference in USB under Linux - it seems as though the controller is identified as an XBox 360 controller when plugged in via USB-C and in Xinput mode.

I think, under "S" (Switch Pro mode), it'll emulate a Switch Pro controller, with seemingly the same GUID.

The only thing I haven't done normally during this, is use Steam Big Picture - does this have a bearing on the GUIDs generated?

This was the output of the SDL_GamepadBind section in config.vdf:

"SDL_GamepadBind"		"030000005e0400008e02000014010000,dev:gen:8BitDo Lite,platform:Linux,a:b1,b:b0,y:b2,x:b3,start:b7,guide:,back:b6,leftstick:b9,rightstick:b10,leftshoulder:a2,rightshoulder:a5,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftx:a1,lefty:a0,rightx:a3,righty:a4,lefttrigger:b4,righttrigger:b5,
...

I edited the result to match that of the database (removing dev:gen (their templating for the device - device: Generic Gamepad, it can also be dev:xb1 for Xbox One-based gamepads).

Would the result differ in a different tool, or would it still result in the same GUIDs?

Thanks again! 😄

Thanks for posting the Big Picture map, that too is a duplicate GUID.

Would the result differ in a different tool, or would it still result in the same GUIDs?

Depending on which version of SDL the tool is built with the result may vary, but in most circumstances the GUID should be the same.
