What the title says. My 3DS right shoulder button is broken, so I was wondering if there are any possible ways of remapping it to, say L+B buttons. On PSP this can be done with a CFW plugin, perhaps there is NTR plugin that could do that on 3DS? Any suggestions?
It is indeed possible, just modify the data written in the Shared Memory (https://www.3dbrew.org/wiki/HID_Shared_Memory).
Something similar is done in this software (in this specific file):
https://github.com/Kazo/InputRedirection/blob/NTR-build/injector/source/injected.s
Now, if anyone has done or intends to do it, is another story.
You can always (for a while) use an external control (which is the original purpose of the software that I suggested the source).

No, but as you said it might be possible with NTR CFW (though nothing like this has made yet). There's a way to control your 3ds using your computer, so maybe that can work as an alternative.
This is just changing from "Is there any way?" to "Will someone code this for me?". To answer your question - it should be possible. You can either code a plugin for NTR, code another homebrew application (or even CFW) or you can modify the data written to the shared memory.
That depends on how much the developer is willing to ask for, how much your willing to pay, and how much you need this done.
At some point, it's cheaper to just buy a new 3DS or look into the alternative methods that have been outlined.
1. use your 3ds as a controller with a app that i dont remember
2. use xbox360emulator then use your 3ds controller on your 3ds that controlling that controller
3. remap buttons

To be honest, I don't really need this done, its just a minor annoyance. On the second thought, I don't think I care about missing shoulder button enough to pay for a software workaround (or at least to pay enough for someone who can actually do it to bother). The only reason why I've made this thread is because I can't physically replace the broken shoulder button - its connector is missing on the motherboard:
So given how many NTR plugins are out there, I thought that surely, there has to be one that does that. It's kinda funny how we have a homebrew method of mapping 3DS buttons to external controller, but not to remap them on the system itself. I'll just use what we've got for now, hopefully, something like MacroFire for PSP will be available for 3DS eventually

Use input redirection for NTR.
It technically uses the computer for inputs, but you can then use the 3DS controller normally while pressing a key on your keyboard when you need R.

I wonder if it's possible to solder a new connector on, or solder the switch straight onto the motherboard?The only reason why I've made this thread is because I can't physically replace the broken shoulder button - its connector is missing on the motherboard:
Chop off the ribbon cable, solder very thin wires straight from switch to correct place on motherboard.

Yes, technically speaking, it is possible to solder a new connector (not the switch directly), but my manual skills are NOWHERE good enough to even attempt that (+ I don't even have the right soldering iron for that kind of job). If you take a closer look at the picture that I've posted, you'll notice my shabby job of soldering the charging port to the motherboard - and in that case, the contact points were way bigger and easier to access. An electronical engineer could probably do that with the right set of equipment, but I'd get charged more for that than a second-handed, old 3DS is worth.I wonder if it's possible to solder a new connector on, or solder the switch straight onto the motherboard?

The reason why my 3DS shoulder button connector is missing is because after the shoulder button in my console started occasionally not responding (due to a broken ribbon), I've decided to replace it with the one I bought off eBay. The only problem with it was the ribbon plug was very tight in the socket (way tighter than the original plug), so when I've dissassembled my 3DS to hardmod it, the connector got ripped off - the ribbon cable was in tact, just missing the connector that you can see on the picture you've posted, which was still sitting in the socket. I've tried prying it off over and over, I even tried to stick it to a pin with a super glue in hope of pulling it out, but it only made things worse to the point, where even if I managed to get it out, the socket would be no longer usable, so I decided to remove it off the motherboard entirely. If anything can be learned from that, its to never buy 3rd party (chinese) "replacement" ribbon cables.

I actually found this thread while looking up to see if it was possible for other reasons. I played around with Kazo's InputRedirectionNTR code, and found out that it can be done, and actually got it to work with the combo you wanted (L+B = R). I've posted the CIA here, and the code is here if anyone else wants to look at it. My changes are in injector/source/injected.s.
Can you PLEASE do something like this, except mapping B to Y, and A to B? It'd be a godsend for virtual console games!

Just saw this. I'll get one put together. Been working on some other projects lately. To clarify, when you press Y you want B, and when you press B you want A?
