[Feature Request]: Swap joycons’ gyro outputs

[edmcintosh]

Feature Description

Is there any way of swapping the gyro signals of the left and right joycon? Or preferring the gyro signal from the left joycon when playing with them detached?

Rationale

Then I could play Skyward Sword left-handed (yes, I know this won't match Link's model), with the left joycon controlling the sword, beetle, loftwing &c. and shield with the right. Or for games that only use one gyro input, I as a left-hander could aim more easily.

It would be possible to do in theory, but it's a bit more complicated than simply swapping gyro data. Mission Control in its current form acts directly on the bluetooth/hid connection and data for individual controllers and has no higher level concept of dual joycons, joycon orientation etc. This stuff is determined somewhere downstream in another part of the OS. To make this work, Mission Control would need to be tracking controller states from the hid module in order to know when and which joycons are attached in dual mode. This would likely require a more complex representation of the controllers and their state in general than the current setup, which more or less just installs button remapping code between the incoming data and the input buffer that Nintendo code reads from. This is something I will likely work on at some point in the future once the hardware support side of things is more complete. Until then, attempting to do this sort of thing would likely wind up a messy hack.
