Le module hid-mitm (pour remapper les touches) vient de sortir !

3 avril 201916 avril 2019 Badablek

Annoncé quelques jours auparavant, c’est tout nouveau, tout chaud sorti du four (très fertile) du hack sur Nintendo Switch. jakibaki nous offre à l’instant la première version de son module « hid-mitm », dédié aux Custom Firmware, qui vous offre la possibilité de remapper complètement les touches de vos manettes selon votre envie. Le hack fait ainsi un nouveau bond en avant dans la personnalisation, fine, de votre console, pour encore mieux correspondre à vos attentes. Le développeur indique que celui-ci a été développé et testé pour Atmosphère, il ne peut pas garantir son fonctionnement sous ReiNX (seul Custom Firmware qui n’est pas basé sur Atmosphère).

Pour configurer le mappage des touches, vous pouvez, au choix, passer par Kosmos Toolbox ou éditer directement le fichier « /modules/hid_mitm/config.ini ».

En cadeau « bonux », vous pourrez également utiliser n’importe quelle manette bluetooth sur Switch, grâce à une application pour smartphone qui fait office de passerelle. Même si le matériel nécessaire complique pas mal les choses, on peut saluer l’effort (et espérer un jour pouvoir le faire directement sur Switch, sans périphérique supplémentaire ?).

hid-mitm

Sysmodule mitming the Horizon hid (human interface device) services.

Disclaimer:

This sysmodule is in beta! Problems are to be expected. If you encounter any that aren’t listed in the known issues section please report it here if nobody else did already.

Features

Rebind buttons on your gamepads.
Use custom gamepads on your nintendo switch by using your phone/pc as a proxy.

Setup

While hid-mitm will work perfectly fine on stock atmosphere and possibly reinx the recommended setup is to download the latest Kosmos since it comes preconfigured with the awesome Kosmos Toolbox which allows you to easily configure hid-mitm.

On Kosmos it’s just a matter of opening the Kosmos Toolbox, enabling the hid-mitm sysmodule and rebooting.

On Atmosphere, installing hid-mitm can be done by dragging the content of the release.

No help for ReiNX is provided, if it runs that’s fine but if you run into problems please try on a supported cfw before reporting.

No support whatsoever for sxos.

Usage

Rebinding buttons

Simply open the Kosmos toolbox, go to the sysmodule menu and continue to the hid-mitm menu from there (it’s a simple button-press explained in the bottom bar)

After that a screen will pop up in which you can select the button you want to rebind and then what you want it to rebind for.
After you’re done, be sure to touch the button in the middle to save your changes.

You can also configure it manually by editing the /modules/hid_mitm/config.ini file.

Custom gamepads

The way that custom gamepads work with hid-mitm is not by directly connecting the gamepad to your switch but by connecting your gamepad to your phone (and experimentally pc) and then running the hid-mitm app which then in turn sends the input to your switch which will recognize it as an additional pro-controller.

Download the companion_apps.zip from the release page.

Android

Install the hid-mitm.apk from the zip on your phone.
Make sure that your switch has hid-mitm enabled and is connected to the same network as your phone. You can use 90dns if you don’t want your switch to connect to nintendos servers.
Connect your gamepad to your phone
Enter the ip-address of your nintendo switch in the hid-mitm app (it can be found in the network settings) and press « connect »
Your switch now should now pick up your gamepad as an additional pro-controller! 🙂

iOS

Install the hid-mitm.ipa from the zip on your phone. You can use Cydia Impactor for that, don’t worry it will work just fine even without a jailbreak.
Make sure that your switch has hid-mitm enabled and is connected to the same network as your phone. You can use 90dns if you don’t want your switch to connect to nintendos servers.
Connect your gamepad to your phone (please note that apple is rather restrictive with the choice of gamepads that they allow you to use)
Enter the ip-address of your nintendo switch in the hid-mitm app (it can be found in the network settings) and press « connect »
Your switch now should now pick up your gamepad as an additional pro-controller! 🙂

As a workaround to iOS not recognizing a plus and minus button l1+l2+r1+r2+x will result in a plus and l1+l2+r1+r2+dpad-left in a minus.

Hid-mitm can also easily be repurposed to do scripted inputs (for example a « twitch plays »).
Check out the input_pc.py for some reference of how to talk to hid-mitm.

Known issues

In some games the « connect gamepad » dialog will pop up every few minutes when playing in multiplayer with a custom gamepad connected
There are various problems that happen if hid-mitm and sys-ftpd are enabled at the same time.
Some phones have a terrible bluetooth connection which will result in input-delay if using bluetooth gamepads. I can’t do anything about that, that’s an issue with android.
On some wifi-networks iPhones have problems which will result in terrible input delay. You can work around this by just opening a hotspot on your phone and letting the switch connect to that. If you don’t want your switch to use up mobile data be sure to enable 90dns.
Some gamepads won’t have their inputs mapped correctly on android.
If anyone who has experience with android development wants to get that fixed by adding some kind of « setup interface » it would be greatly appreciated.
Tetris 99 doesn’t want to recognize custom gamepads for some reason

Planned features

Support for connecting multiple custom gamepads
Support for motion controls
(maybe) vibration support
Support for « disguising » gamepads as something else. To allow for example to play pokemon with a pro-controller.
