Manipulating 3DS IR sensor?

[Blargaman91]

I've toyed with the idea of having an external controller for the 3DS before but I've always hated having to open such an expensive console and put wires in it. I see people making GameCube controller mods with wires and connectors sticking out of the side and I wonder if no one's attempted using the IR sensor to do all that. I can't find any information on the 3DS IR sensor other than it's used by the circle pad pro, but I'd like to know if it can be used to override the system's main controls as well as add the circle pad pro's controls. Does anyone think that is a possibility?

Sounds very doable i have a broken 3ds xl so if i
ever get time i can look at it and take some pictures
if that might help

Does anyone have info on the IR sensor?

When Sakuri talked about the c stick on the new 3ds in smash bros, he stated that the reason circle pad pro support wasn't added was that it consumed 5% of the processors power. They were pushing the limits of what the 3ds could do, and needed to use all available resources.

I think the reason this isn't so feasable is because support for the accessory would have to be already included in the game. If you wanted to add support, a lot of heavy software modification would be nessessary.

1: A controller accessory would be need to be made
2: A chip to convert the button presses into IR bianary flashes
3: Software would need to be written (and somehow installed) to decode and use the IR signal
4: more software would be needed to spoof the console into thinking the IR inputs are actual controller inputs

The sensor is probably a pretty simple IR detector like those found in TVs. What it really comes down to is software

That sounds like something homebrew could do. I wouldn't know how to do something like that but someone might.

This would be insanely complicated.
A better idea would be to add your own IR sensor and use it to manipulate button presses but it's still more difficult than it's worth.

Well, okay then... I guess I'll stick with wires. Thanks.

https://www.youtube.com/watch?v=0Fj6iIPR2iw theres a capture card with a gc controller funktion. maybe you can contact the developers of this capture card to gather some infos

This was discussed on GBATemp already, and it's not possible. The signal that the 3DS sends out is WAY too tiny, and it operates at a much slower speed than that of a TV remote. Here's the thread: https://gbatemp.net/threads/infra-red-resource-thread.399336/
