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

[Kartik]

Good news is that rehid is in the process list. Can you explain what we need to do for the release posted in gbatemp to create rehid.json?

For example, my rehid.json states the following:
{
"keys":[
{"get":"CRIGHT", "press":"RIGHT"}
]
}

Hmm RIGHT>CRIGHT might be the problem. Change this to something like

{
"keys":[
{"get":"Y", "press":"X"}
]
}

and check. Y should be triggered when you press X.

 

[MarioKartFan]

I think this is working exactly as you intended and the mistakes were my own. My first issue was using an outdated .json format that references "remappings" rather than "keys". Once I got that sorted the rest fell into place. At that point the only issues were self-inflicted. I assumed CLEFT referred to the C-Stick (the nub).
Is there a key command for the C-Nub?

You could try this release along with this json might or might not work.

{
"keys":
[
{"get":"LEFT", "press":"CSLEFT"},
{"get":"RIGHT", "press":"CSRIGHT"},
{"get":"UP", "press":"CSUP"},
{"get":"DOWN", "press":"CSDOWN"}
]
}

 

[MarioKartFan]

That works! Wow. This is amazing. The camera controls in Super Mario 3D Land are finally useful for the first time ever. Luigi's Mansion 2 benefits from mapping touch screen to Select (why they didn't set it up that way be default is a mystery). This is really, really exciting stuff. Thank you so much.

 

[MarioKartFan]

Wow. In Ocarina of Time, we can finally use ZR, ZL and Select to remap the ridiculous "Button I", "Button II" and "Items" from the Touch Screen to actual controls. We can also map NAVI and the Ocarina to the DPAD or the C-Nub. This is huge!

Nice to know! Others who wanted to map cnub, please use the release and json from my last post and test. You can modify the json as per your needs. Let me know if it works for you all well.

Can you swap the circlepad with the nub? I would like to use it for some games to reduce wear-and-tear of the circlepad

Depending on the game, this might work:-
{
"keys":
[
{"get":"CLEFT", "press":"CSLEFT"},
{"get":"CRIGHT", "press":"CSRIGHT"},
{"get":"CUP", "press":"CSUP"},
{"get":"CDOWN", "press":"CSDOWN"}
]
}

 

[MarioKartFan]

In case it is helpful, here is an image I created to help map Touch Screens to physical controls (yes, I'm aware that it's a 320x240 screen. But personally I found a visual aide helpful when setting up controls for the more densely populated touch screens (like Ocarina of Time and Metroid 2):

}

Remapping games that use ZL-ZR like Xenoblade still freeze the console after the 3DS logo. Aside from that, the C-Nub remapping works great, its great to use it as the camera controlling button, instead L-R or D-Pad. (This is very useful on games that relies on the C-Pad to move the character and D-Pad to controlling the camera)

Xenoblade still freezes? That is strange. Could you try the release version form github and check if it qorks?

 

[MarioKartFan]

I really cannot express enough thanks for this. This is easily one of the most significant developments for 3DS homebrew perhaps ever. I just remapped the Up and Down controls to the C-Nub for Luigi's Mansion. It's a marvel that Nintendo didn't add this to the firmware when they released the N3DS.

 

[MarioKartFan]

@Kartik I notice a possible bug with rehid. The home key no longer works properly when running a home brew application. It just turns the screen black. It’s possible to enter Rosalina and reboot from there. The home key seems to work fine for official games (just not home brew).

 

[Stefano_Lassandro]

I've dowloaded the version of rehid you've posted up in the forum (the one with the c-stick example) and I tried remapping the input like so:

{
"keys":
[
{"get":"CSLEFT", "press":"Y"},
{"get":"CSRIGHT", "press":"A"},
{"get":"CSUP", "press":"X"},
{"get":"CSDOWN", "press":"B"}
]
}

I saved it as a game-specific remapping (The game in question is Resident Evil: The Mercenaries, ID: 0004000000038B00). The file is located at path: F:\rehid\0004000000038B00\rehid.json
When I launch the software, the A, B, X and Y buttons stop working, and pressing directions on the c-stick doesn't count as the pressure of any of the ABXY buttons. I'm pretty sure I'm doing something wrong, any help is widely appreciated! Thanks in advance.
(PS: The game doesn't include the use of the c-stick or the ZL and ZR buttons, but from what I've read in the forum it should work anyways).

 

[MarioKartFan]

@Stefano_Lassandro
You have your order flipped. Switch CSLEFT with Y, CSRIGHT with A, etc.

I did that on purpose. Let me explain: the game uses ABXY to control the camera, and I wanted to use the c-stick intead.

@Kartik I notice a possible bug with rehid. The home key no longer works properly when running a home brew application. It just turns the screen black. It’s possible to enter Rosalina and reboot from there. The home key seems to work fine for official games (just not home brew).

I'm also experiencing this bug, already described above. But my console (New3DS) just freezes, doesn't go to any black screen. So yeah, it's probably a common problem.

I know what you are trying to do. You have the order flipped. You are mapping the c-stick to ABXY instead of ABXY to the c-stick. You need to flip your .json file

{
"keys":
[
{"get":"Y", "press":"CSLEFT"},
{"get":"A", "press":"CSRIGHT"},
{"get":"X", "press":"CSUP"},
{"get":"B", "press":"CSDOWN"}
]
}

 

[Nutez]

To show my appreciation for Kartik's excellent work, I thought I'd share a few of the biggest control/gameplay improvements I've found while experimenting (edit: and some other, more minor remaps).

Spoiler: Kingdom Hearts 3D

{
"keys":
[
{"get":"UP", "press":"ZL"},
{"get":"DOWN", "press":"ZR"}
]
}

This lets you manually scroll through the Command Deck while still being able to move freely.

Spoiler: Terraria

{
"keys":
[
{"get":"LEFT", "press":"CSLEFT"},
{"get":"RIGHT", "press":"CSRIGHT"},
{"get":"UP", "press":"CSUP"},
{"get":"DOWN", "press":"CSDOWN"},
{"get":"CSLEFT", "press":"LEFT"},
{"get":"CSRIGHT", "press":"RIGHT"},
{"get":"CSUP", "press":"UP"},
{"get":"CSDOWN", "press":"DOWN"},
{"get":"ZR", "press":"START"},
{"get":"Y", "press":"ZR"}
]
}

The D-Pad to C-Stick doesn't seem to work for now but it's the C-Stick to D-Pad part that matters most. With a little practice you can mine on the move and fight while running backwards (without touch screen).

Spoiler: Tales of the Abyss 3D

{
"keys":
[
{"get":"L", "press":"CSLEFT"},
{"get":"R", "press":"CSRIGHT"}
],
"touch":
[
{"get":[80, 60], "press":"ZL"},
{"get":[240, 60], "press":"ZR"}
]
}

Controlling the overworld camera with C-Stick feels nice and mapping ZL&ZR to the touch screen makes for easier combos.

Spoiler: The Legend of Zelda: Link's Awakening DX

{
"keys":
[
{"get":"A+B+Y+START", "press":"SELECT"},
{"get":"A+B", "press":"X"}
]
}

A game that really benefits from the button-combo mapping. Gives you painless access to the save menu and allows for easier bomb-arrows or the sword-shield combo.

Spoiler: The Legend of Zelda: Ocarina of Time 3D

{
"touch":
[
{"get":[300, 20], "press":"ZL"},
{"get":[300, 220], "press":"ZR"},
{"get":[20, 220], "press":"START"}
]
}

Probably one of the most obvious games to benefit from remapping and it has many options. I went with Start for the Ocarina and ZL/ZR for Item I/II respectively. I left the C-Stick unused though, as hopefully it will be possible to map it to the C-Pad in future for aiming similar to Majora's Mask.

Spoiler: The Legend of Zelda: A Link Between Worlds

{
"keys":
[
{"get":"LEFT", "press":"CSLEFT"},
{"get":"RIGHT", "press":"CSRIGHT"},
{"get":"UP", "press":"CSUP"},
{"get":"DOWN", "press":"CSDOWN"},
{"get":"B", "press":"ZR"},
{"get":"Y", "press":"ZL"}
]
}

This allows you to adjust the camera for greater forward sight while moving and still attack.

Spoiler: Pokemon Crystal/Silver/Gold

{
"keys":
[
{"get":"SELECT", "press":"Y"},
{"get":"LEFT", "press":"L"},
{"get":"RIGHT", "press":"R"}
]
}

Pseudo-imitates the menu controls of newer Pokemon games.

Spoiler: Final Fantasy Explorers

{
"keys":
[
{"get":"R", "press":"ZL"},
{"get":"L", "press":"ZR"},
{"get":"ZR", "press":"L"},
{"get":"ZL", "press":"R"}
],
"touch":
[
{"get":[120, 190], "press":"START"}
]
}

Comfort swap of shoulder buttons and easier triggering of pet monster attacks.

Spoiler: Animal Crossing: New Leaf

{
"keys":
[
{"press":"CSRIGHT","get":"RIGHT"},
{"press":"CSUP","get":"UP"},
{"press":"CSDOWN","get":"DOWN"},
{"press":"CSLEFT","get":"LEFT"}
],
"touch":
[
{"press":"ZL","get":[60,10]},
{"press":"ZR","get":[180,10]}
]
}

Simple C-Stick to D-Pad and quick access to other menus.

Spoiler: Lego City: The Chase Begins

{
"keys": [
{
"press": "ZL",
"get": "LEFT"
},
{
"press": "ZR",
"get": "RIGHT"
},
{
"press": "CSRIGHT",
"get": "R"
},
{
"press": "CSLEFT",
"get": "L"
}
],
"touch": [
{
"press": "START",
"get": [
35,
205
]
}
]
}

C-Stick camera controls, disguise switching on the move and button activated radar.

Any other recommended remappings out there to share?

 

[NanashiFinal13]

@Nutez i was just about to make a thread to share rehid configs
But instead of that, i just post it here like you did.

Spoiler: Shingeki no Kyojin 2: Mirai no Zahyou

{
"touch":
[
{"get":[231, 193], "press":"ZL"},
{"get":[306, 193], "press":"ZR"},
{"get":[156, 197], "press":"START"}
]
}

This let you search and choose the any item you want when you'r flying with the ODM or even when you are attacking a titan. ZL and ZR works as the arrows on the touchscreen to search trough your bag and you select the item with START

Spoiler: The Amazing Spider-Man

{
"keys":
[
{"get":"LEFT", "press":"CSLEFT"},
{"get":"RIGHT", "press":"CSRIGHT"},
{"get":"UP", "press":"CSUP"},
{"get":"DOWN", "press":"CSDOWN"}
],
"touch":
[
{"get":[68, 112], "press":"ZL"},
{"get":[258, 112], "press":"ZR"},
{"get":[160, 211], "press":"START"}
]
}

With it, you can control the camera with the C-Stick instead on the D-Pad, so now you can freely web swing without having to stop to move the camera. Also, the Retreat and Dodge touch buttons were remapped to ZL and ZR, and the Take Photo touch button its remapped to START button.

Spoiler: Spider-Man: Edge of Time

{
"keys":
[
{"get":"LEFT", "press":"CSLEFT"},
{"get":"RIGHT", "press":"CSRIGHT"},
{"get":"UP", "press":"CSUP"},
{"get":"DOWN", "press":"CSDOWN"}
],
"touch":
[
{"get":[296, 25], "press":"ZL"},
{"get":[150, 130], "press":"ZR"}
]
}

Same camera config as Amazing Spider-Man, Time Paradox and Spider-sense touch buttons remapped to ZL and ZR.

Spoiler: Kid Icarus: Uprising

{
"keys":
[
{"get":"Y", "press":"CSLEFT"},
{"get":"A", "press":"CSRIGHT"},
{"get":"X", "press":"CSUP"},
{"get":"B", "press":"CSDOWN"}
],
"touch":
[
{"get":[32, 215], "press":"ZL"},
{"get":[75, 215], "press":"ZR"}
]
}

If you choose to control the retina/camera with Y,A,B and X (you can change this on options menu), this buttons are remapped to the C-Stick. ZL and ZR now trigger the Aerial Powers , ZR also trigger any power you choose on Land battles.

Spoiler: Back in 1995 64

{
"keys":
[
{"get":"RIGHT", "press":"CRIGHT"},
{"get":"LEFT", "press":"CLEFT"},
{"get":"UP", "press":"CUP"},
{"get":"DOWN", "press":"CDOWN"}
]
}

The game try to emulate old games like PSOne horror games, and you can only move the character using the D-Pad. With this config, you can use the C- Pad for movement.

Spoiler: Transformers Prime: The Game

{
"keys":
[
{"get":"LEFT", "press":"CSLEFT"},
{"get":"RIGHT", "press":"CSRIGHT"}
],
"touch":
[

C-Stick now controls the camera instead of D-Pad, Start triggers the Upgrade Power touch button.

Yet another remap to control the camera with the C-Stick.

Spoiler: Super Mario 3D Land

{"get":[289, 163], "press":"ZR"},
{"get":[160, 126], "press":"START"}

}

Control the Arrow touch buttons with ZL and ZR, use your stored power with START.

Spoiler: Yo-Kai Watch

{
"keys":

{"get":"L", "press":"CSRIGHT"},
{"get":"R", "press":"CSLEFT"}
],
"touch":
[
{"get":[31, 222], "press":"START"},
{"get":[100, 226], "press":"ZL"},
{"get":[164, 226], "press":"ZR"}
]
}

Camera control with C-Stick, Bicycle, Radar and Map touch buttons remapped to ZL, ZR and Start.

Spoiler: Tom Clancy's Splinter Cell 3D

{
"keys":
[
{"get":"Y", "press":"CSLEFT"},
{"get":"A", "press":"CSRIGHT"},
{"get":"X", "press":"CSUP"},
{"get":"B", "press":"CSDOWN"}
],
"touch":
[
{"get":[12, 22], "press":"ZL"},
{"get":[310, 16], "press":"ZR"},
{"get":[10, 99], "press":"Y"},
{"get":[177, 88], "press":"B"},
{"get":[290, 85], "press":"A"},
{"get":[104, 43], "press":"X"},
{"get":[158, 44], "press":"START"}
]
}

The camera buttons (Y,X,A,B) were remapped to the C-Stick, the EEV Hacking touch button its remapped to ZL, Thermal Vision touch button to ZR, Map touch button to X, Whistle touch button to START, and the 3 main weapon to Y, B and A (Y is the regular pistol, B is the Assault Rifle, you can press B twice to use the 1.5 reflex sight, and A is the grenades).

Here's an alternative remap that, on this remap the weapons are remapped to X,Y and B, the Map touch button is remapped to START button, there's no Whistle remap and the A button its free (to access Rosalina menu and that kind of stuff). I think this is one of the 3DS games that benefits the most of rehid. In my honest opinion, the worst thing about Chaos Theory port on 3DS is not the graphics or the loading times (you can mitigate that using the New 3DS clock speed), its the horrible control scheme.

You can now control the character movement with D-Pad. (and also the C-Pad as default)
In some of game areas you need tighter controls and (in my opinion ) the D-Pad does a better job than the C-Pad (but still i like to use the C-Pad). The downside is that now you can only use the bag items with the touchscreen. (normally, you can use the touchscreen or the D-Pad)
