[Feature Request]: Simulate Attached Joy-Cons

[mayamelloid]

Feature Description

allowing a connected controller to be read as if they're physically attached joy-cons

Rationale

this is mainly for let's go pikachu and eevee. i'm aware there have been efforts to make a connected controller act as joy-cons connected via bluetooth, but this actually wouldn't be the best solution for these games specifically; in handheld mode, the games work with "normal" controls with attached joy-cons. this means that if a pro controller is spoofed as if they're attached joy-cons, you could actually play them normally in handheld mode with a bluetooth-connected controller (and potentially in docked mode with something like reverse-nx?)

the latter docked mode comment is also especially useful for people who can't play in handheld mode (personally, my switch's screen is completely non-functional), as if it works, it would allow this game to be played with standard controls in docked mode with a normal controller

Additional Details

honestly, i'm unsure if anything like this has been attempted? it feels really obvious (which is why i hadn't made this issue in the past), but i've done a decent amount of googling and haven't found anything like this. i was reluctant to make the issue because this really feels like something people would have already suggested and issues already been found ages ago, but i really don't think this has been suggested unless if i missed something really obvious

I'm not sure if this has been suggested before. It's probably possible to redirect a controller's inputs into the handheld state via the hid:dbg interface for virtual gamepads. I think it would require some architectural changes to Mission Control in order to do it cleanly though.

and potentially in docked mode

Handheld controls don't work in docked mode, but I have some patches that enable that.

that's great to know! i won't keep my hopes up to see this soon since stuff like this can take time (and there are probably higher priorities anyways, especially since i don't think this would help with any other games that require joy-cons? i may be wrong though) but knowing it's likely possible in and of itself is great

and potentially in docked mode

Handheld controls don't work in docked mode, but I have some patches that enable that.

for clarity, i meant in docked mode with something like reversenx faking handheld mode, but that seems to be a moot point considering it's possible to reenable them. (and i'm unsure if that's even how reversenx works)

this actually makes me wonder if lgpe would accept reenabled handheld controls in docked mode; it'd be nice if you didn't have to fake handheld mode and get lower res to play it with a proper controller, but that's sorta off-topic to mission control itself
