Homebrew [WIP] rehid:- Button remapping for 3ds

[Kartik]

@Kartik Congrats! I tested this version on several homebrew apps and I can get back to home with no problems! It also resets correctly the buttons when in the Home Menu. I've noticed another problem tho: if I pause the game and go to the Home Menu, and then get back to the game, the C-stick stops working (in-game). That's the case only if the input of the C-stick is remapped. Even if I close the software and relaunch it, the C-stick won't work (in this state, it works in other titles and in the Home Menu). After the console is rebooted, it works on the title again.
I also tried exiting the game and playing one that requires the use of the C-stick: it will work on that one, but it still won't work for the title that "broke" it.
Hope that's enough info. Thanks again for taking the time to develop such a useful and simple to use program!
Edit: fixed typo

That would be cool! I'd love to share some of my configs too

Please try this and tell me if it works

 

[Stefano_Lassandro]

What game are you tetsing with and could you share the config for that game?

The game in question is Resident Evil: The Mercenaries 3D (EUR, bought from eShop).
Here's the folder:

Sorry I just saw this, and yes, it works perfectly! You was really fast, good job.

I've been trying to map Samus Returns so I could use the D-Pad to move the character but it doesn't seem to be working, I don't think I put anything wrong in the config file.

Here it is if you want to have a look:

Edit: I didn't know you had to put "dpadtocpad":true in the config file.

hi uh (noob question sorry) so after following the instructions and booting up my game the remapping doesn't work, i'm trying to swap x and b, my json file looks like this:
{
"remappings":[
{"get":"B", "press":"X"},
{"get":"X", "press":"B"}
]
}
i'm editing it w notepad++ if maybe that's the problem?? sorry i really just know almost nothing about this-

Start your game, open rosalina menu, go to process list, scroll down and check whether there is a process named "rehid" and change the json file to this:-
{
"keys":[
{"get":"B", "press":"X"},
{"get":"X", "press":"B"}
]
}

Does it work now?

I did that and when opening rosalina menu i found no "rehid" process... maybe i messed up the file location or smth? the rehid folder is in the root of the sd card and the rehid.json is in the folder, the extracted zip files (code.bin and exheader.bin) are both in luma/titles, i tried rebooting my 3ds and nothing happened, also reinserting and taking out the sd card but nothing either

Had you by chance have the game patching enabled on the luma page when holding start and power?

Yeah, it was on before this and i double checked if it was enabled before downloading anything

Make sure that game patching is on, and code.bin and exheader.bin are in a folder named `0004013000001D02` in `luma/titles` and not directly in `luma/titles`

tysm, it was directly in luma/titles and it works now

Hi! I've got a crash report. I was using the CTRX file manager app and I get crashes every time I try going back to the Home Menu. I've moved rehid from the luma titles, and it doesn't crash anymore, so I'm pretty sure rehid is what's causing the crash. The crash dump will follow:

Do any others app crash? Ctrxplorer is based around a very old lib called citrus and is doing some custom stuff to gain control over things, i guess that is what is most likely crashing.

EDIT: I just tested ctrxplorer and indeed it crashes, if no other titles crash, it is most likely an issue with ctrxplorer and I don't think it can be solved from rehid side of things. Disable rehid when you want to use ctrxplorer by disabling game patching and then enable it again when you want to use rehid.

Oh I see now. Thanks for taking the time to check what the issue was about!
Edit (note): I've tested several other apps, no crashes.

You can use GodMode9, GodMode9i or 3DShell to manage your files when needed.

Yeah, I use 3DShell and Universal Manager as an alternative to CTRX. Never used GodMode9 for file management actually.
Thanks for the advice btw.

Hi @Kartik, first of all, I think you should apply to get a proper developer account tag as recognition for all this ground-breaking work . Secondly, I don't really understand the code very well so I wanted to ask: do you think that rehid might cause the battery to drain slightly quicker than the regular hid? For example, does the irrst always get initiated even if N3DS buttons aren't included in a remap json? Thanks .

Yup irrst is always initialized but I don't think there is going to be a significant battery drain. The way it currently works, selectively initializing ir:rst might introduce bugs.I'll have to look into this further.

On further inspection and testing I can confirm this is not doable atm, it introduces lots of new bugs.

Also, is somebody good at adobe illustrator who can make a n3ds vector for me(something like this)? I need it for the upcoming homebrew app which will allow you to create remaps directly from 3ds.

Does it work now?

Yes, but I have another problem, in this game, the dpad is used to select abilities and I want to map that function to the c-stick, but when I do this the game crashes.
