Homebrew [WIP] ButtonSwap3DS - Remap buttons on your 3DS

[rolim91]

Sorry, I was wrong

I was checking .allMap


I havent relly tried this out physically. I was just reading the code. And trying it out by hand. I am trying to learn how to write and read assembly code right now.


With A+B = Select code

Using 0x3 for button mask and 0x7 for XOR mask.

A+Select pressed shouldnt go through because of the check.

B+Select pressed shouldnt go through as well.

This is because of: cmp r1, #0

Sorry about that. I'm still trying to learn this stuff.



Also, I think its possible that register R2 gets overwritten when multiple .anyMap and .allMap calls are true.

Eg.

A + B -> Start
B -> Y, Y->B

If code written in this order, then user presses A+B

A+B -> Start call goes through writes to R2
B -> Y, Y -> B call goes through overwrites R2


Instead it should have been:

A+B as A+Y as button pressed since B is Y



To be specific

@ A + B -> Select

ldr r3, =0x3     @011
ldr r4, =0x7     @111
bl .allMap


@ B -> Y, Y -> B

ldr r3, =0x801  
ldr r4, =0x801
bl .anyMap

In this case if A + B are pressed, Y is pressed since @B -> Y, Y -> B call is last and overwrites R2.


I hope this helps

Edit: Formatting and other stuff

Hi folks, someone redirected me here saying there is some very helpful people around . Basically my c-stick broke and is sending random direction non-stop with no way to fix it. I was hoping there is a way to disable the input from c-stick and I'll just use my N3DS as a O3ds.

I think that's exactly the issue. I had thought it would be OK to keep the temporary values in one register, but now I'm seeing that it's affecting any previous values. The order of mappings may fix this, but I doubt that's a valid fix for every situation.

Well, the easy fix would be to open your N3DS and disconnect the c-stick from the circuit board. I don't have the c-stick mapping working yet, but it should be possible to disable the c-stick once that is working. We'd just redirect the process that looks for c-stick data to an area of memory that has the c-stick at neutral all the time.

Thanks! I used this to swap L+R for OOT 3D. Using L for the camera was driving me crazy, my finger never wanted to be there, using R is soo much easier.

 

[mcaboosec]

@Vague Rant, can you test this build? I changed how the swaps work, and it should be much more accurate. If it works, I'll push my changes and update the documentation. The changes I made will also do away with XOR masks, which should make it easier for people to use.

Works absolutely perfectly, mcaboosec. Two, three and four-button combos all worked correctly. Fantastic stuff!

For reference, I use Snes9x for 3DS with the internal Nintendo "Controller Test Cassette (Japan)" ROM for testing, which shows a visualization of a SNES controller and highlights the buttons when pressed. There's probably better button testers around, but this one's nice and intuitive as long as the SNES layout is all you need (i.e. no analog stick).

yo can i request a compiled version that swaps X and B?

Here you go. Standard version was tested, mode3 not tested.

This is using the updated codebase from mcaboosec, so button combos were also tested and working.

Thanks man, gonna test it soon

I actually made one to do it a couple days ago. Here it is! For those interested, here is the mapping:

ldr r3, =0x40
ldr r5, =0x7FF000
bl .cpad            
ldr r3, =0x80
ldr r5, =0x800000
bl .cpad            
ldr r3, =0x10
ldr r5, =0x0007FF
bl .cpad            
ldr r3, =0x20
ldr r5, =0x000800
bl .cpad

The documentation had previously indicated that you should have bl .touch at the end of each mapping. It should have been bl .cpad.

Thanks so much. I've been wanting this for ages. I never really got into the circle pad for mario kart 7, because it's so slippy, my thumb just keeps slipping off it. I had to keep licking my thumb and rubbing it around on my forefinger to grippy it up. Now I can finally play with the D-pad, as I should always have been able to

Hello guys
Is it possible to swap ABXY buttons with the circle pad ?
If yes , can someone please compile a version that does it ?
Thanks

I have a version ready to build, but you'll lose ABXY. Do you want these on the control pad?

 

[Vague Rant]

I interpreted @Demnyx's request as being for ABXY to be input using the Circle Pad itself, which sounded complicated so I didn't bother trying. :V

Ahh sorry i wasn't clear
I only want for ABXY buttons to be the circle pad no matter if i can't use ABXY buttons anymore

Hey mcaboosec, I thank you again for the Cpad.cia. It's excellent in mario kart 7.

But in zelda link between worlds, it seems more like this. So I think it's slightly out (my picture is a little exaggerated)

Alright, here you go! Let me know if anything is broken, I just updated my buildtools.

Interesting. I'll test it a bit later to see what I can find.

Thanks !
Will try

EDIT : Hum , doesn't work i can't use ABXY buttons and they aren't replaced by circle pad
Also i want d-pad to replace ABXY buttons if possible
Thanks again

 

[Wishi]

Can anyone make one that:
Swaps R to Y Button , and Swap Y button to Up D pad
Please , this would make my MHXX gameplay perfect ! Because I'm having a really bad time with my r button xd Thanks !

 

[neobahamut1989]

Sir, can i get remap button for:
Swap L with down D-pad and R with up D-pad
my little brother 3ds R button broken but we still playing ff explorer, monster hunter, with it. I already take a look for debug myself, but damn......confuse with make install, HID, and installation of devkitPro.

 

[R9HAX]

I have a question for you can you use this to disable buttons Id like that option in another update I hate the L2 and R2 buttons on the new3ds
