Hacking [Tool] Joy-Con Toolkit

512KB (524 288 byte)

OK, checked both of them out, and they are the correct size. Not sure why it would take a while to dump 512KB of data over Bluetooth though.

Not sure why it would take a while to dump 512KB of data over Bluetooth though.

As far as I can tell, actually sending the data over Bluetooth doesn't take long at all, using UART commands to retrieve the data from SPI flash and prep it to be sent over Bluetooth is what takes a while. This would explain why it seems slow overall, but progress jumps forward in small bursts on the PC side.

Oh, OK.

seriously wish I could use my tablet as a bluetooth adapter on my pc or use an android version of this to do this, well, no colors for me

Hi there!

I've successfully customized my gray Joy-Con colors, so thank you so much OP for making this tool!

EDIT: After checking, it seems it did actually change the colors of my Pro Controller (problem described below), I can see the pink I've selected and it all works perfectly. It does work, but the bugs in the UI and stuff are still present, but luckily it does actually work

I can't seem to customize my Splatoon 2 Pro Controller though. Connecting it to my Mac (running Win10 by dual booting) goes fine. When opening the tool however, it gives me a different MAC-address and color set every time I open it. The serial number is all wrong, too. When trying to choose a body color and submit it, it says it's done so successfully but the button turns black (telling me it hasn't worked) and restarting the tool gives me random colors again.

I have an SPI dump for you if you'd like to have it. It's a dump I made after trying to change the colors once, but since it seems to have no effect, the dump should still be vanilla.

Another question: are planning to make this tool open source any time? I'd like to participate if possible. Mainly a C# developer but would like to do some stuff with C and C++, too.

Once again: awesome tool!

Edit: spelling

@NotPengi OP has advised against changing the Pro Controller color for now, though I'm not sure why.

@NotPengi OP has advised against changing the Pro Controller color for now, though I'm not sure why.

because it's untested. it might work, it might brick your controller, it might even brick your Switch.

 

[CTCaer]

New version released!
Check OP for changes.

Who ever had strange crashes, please try the new version.
Pro controller is still untested and I will need an SPI from old version, from new version and from shiny's hid whispering.

@NotPengi:
Please PM it to me.
I think that Pro controller SPI flash structure is different than joy-cons because of different Microcontroller..
Lastly, I was planning to release the source on github since start. But now this will take a while, until I make Pro Controller logic usable and clean the code a LOT!

 

[doriandu45]

New version released!

Yes! It's now working, thanks!

I also have a SPI dump of my Pro Controller (with your tool, I can't compile shinyquagsire23's tool, maybe because it's made for Linux), can I post it here or somwere else (I'm new, that's why I ask you before doing anything)

 

[SomeGamer]

Body color and... Body color?

 

[Rafa10PT]

Nice!

 

[Jayro]

Success! Went from gray to neon. I custom painted my joycon, they were originally gray but I bought the neon shells. Waiting for those to arrive. Picture was taken before I changed button color but I don't think there would have been a difference on picture.

Where does one get milky white joycons?

 

[luk_pop]

Can you ask for the program to run without connected joy-con and connect them by start button or something to connect joy-con?

Joy-Con Toolkit v1.2

Warning: Don't write any colors for pro controller yet. As I don't have one, don't know if the colors are in a different address. Can someone send me a dump with shinyquagsire23's tool through usb and through v1.2 by Bluetooth?

Summary:
Since months ago, I bought yellow joy-con shells and modded my Joy-Cons. Then I found Shinyquagsire23 HID-Joy-Con-Whispering and changed my joy con colors and this reflected my new neon yellow color in-game.

I always wanted to make an easy tool for that, for the community. So here it is with some additional goodies.
Have fun creating funky combinations.

What it can currently do:

• Change colors of your Joy-Con
• Backup your SPI flash
• View S/N and MAC address
• View Firmware version

Prerequisites:

• .net framework v4.5.2
• Visual c++ 2015 x86 redist
• Bluetooth adapter, USB or built-in
• Windows PC

Changelog:
v1.2

• Now you can see real Joy-Cons and Pro controller for color view.
• Updated Neon-Yellow color with retail values.
• You can now save your own custom colors!
• Fixed many bugs and crashes.
• Every communication produces rumble confirmation.
• Added led support. 1st Led: initialized, 4th Led Blinking/Solid: Standby/Write sent.
• Changed SPI dump logic a little bit. Users with Pro controllers or with crashes, please try again.
• I still need a correct SPI Dump from a Pro. One with v1.2 and one with Shiny's tool.
• Disabled Pro controllers color write for now.

v1.0

• Initial release

Before you do anything, make a backup of your SPI flash.
When you change colors, before 3.0.0 update you need to restart your Switch and then pair, for colors to take effect.
For 3.x.x just pair the controller with Switch.
The custom colors in the color dialog are the retail ones.

Special thanks:
Everyone at Nintendo_Switch_Reverse_Engineering: General BT protocol usage
@shinyquagsire23: General hidapi and BT protocol usage
@SciresM: General hidapi usage for windows
@Ceri: Neon-Yellow hex color values

If someone knows any original retail color (like neon-yellow, splatoon, etc) please reply here with the hex code

I made a dump with v1.2 of my Splatoon 2 Pro Controller, haven't been able to make a dump with SQS's program.

EDIT: Disregard this, something went wrong. Gonna dump it again over bluetooth right now, I'll post the new dump when it is finished and I checked it!

Just letting you know, that file is all zeroes.

Oh derp. Does the dump even work via cable?

--------------------- MERGED ---------------------------

Okay, it dumped correctly I think. Again, this is the Splatoon 2 Pro Controller.

That file seems oddly small (maybe because it's a Pro Controller), but hey, it's not all zeroes anymore!

The original file is 512kb but I couldn't upload .bin, so I rarred it which is allowed

Now I feel stupid, even unpacked before having a look, and the original is indeed 512.

Better than my mistake of uploading 512kb worth of nothing
