wip: emulate steam_input through sdl3 by f8ith · Pull Request #242 · Detanup01/gbe_fork

f8ith · 2025-06-03T15:38:22Z

~~Very~~ WIP PR, currently handles most of the major controller types. Tested to work on Elden Ring Nightreign with a stock Dualsense.

Implements

Querying controller types and connected controllers
Rumble
Action set layers
GetActionOrigins, GetGlyphForActionOrigin, GetActionOriginFromXboxOrigin....

Note on XInput Emulation

Real steam emulates Xinput for non-Xinput gamepads on windows. We could attempt to do the same by hooking Xinput same way that Steam does, but it's tricky and would only work well on experimental builds most likely

TODO

Fix reconnecting controllers
Implement action layers -> fixes gamepad detection
Loading action set layers
Test rumble
Customizable deadzone, layers, etc.

- steam_input emulation with sdl3 instead of gamepad.c - implemented ActionSetLayers - added configurable deadzone under main::gamepad

Not sure why protoc is failing on github actions but builds fine locally

The deps cache in Github Actions has now been regenerated, and PR #249 builds successfully.

Is this still being worked on? I was trying to build for Mac but I'd have to port the gamepad library.

f8ith · 2026-01-21T15:38:35Z

Is this still being worked on? I was trying to build for Mac but I'd have to port the gamepad library.

in terms of emulating the basic steam input api itself, the code should be relatively complete though a little messy but rumble + multiple controller still hasn't been tested because I do not have access to those things/a game with rumble myself right now.

What do you mean by porting the gamepad library? sdl3 should be crossplatform though you may need to edit the build script

ilcheese2 · 2026-01-21T22:02:06Z

I was talking about the library that is currently used. I ended up implementing the functions with Apple's Game Controller Framework, and it built, but I haven't verified whether it works.

f8ith · 2026-01-21T22:06:00Z

This PR should remove the need for libgamepad. With SDL iirc there shouldn't be any relevant code that references libgamepad anymore.

utkarshdalal · 2026-01-23T13:38:20Z

Curious about this one, would it fix issues where games aren't detecting the gamepad? I just opened an issue for this for No Man's Sky. If it's complete and we're only waiting to see if rumble works, I could request someone to test for you, or we could put the new implementation behind a flag like sdl3_input=1 (0 by default, legacy input)

utkarshdalal · 2026-01-26T10:00:39Z

@f8ith sorry for the ping, but would love your thoughts on the message above! ^

f8ith · 2026-01-27T16:32:25Z

would it fix issues where games aren't detecting the gamepad?

It should enable controller functionality, this PR stubs/implements most steam input function calls. You could try using the compiled dlls

add a flag like sdl3_input=1

Since I already have added a couple settings for other functionality I could add this in probably within this week

utkarshdalal · 2026-01-27T16:57:42Z

Where could I get the compiled DLLs?

I'd also love to learn more about what the changes do if you're open to sharing, so I can contribute too.

Detanup01 · 2026-01-27T19:32:00Z

Hey If you add rumble (AND IF Works with Xbox controllers) I can test them with a new test "game" that just start rambling your controller for X sec if has one & etc.

No DLLs being made since the PR is in Draft mode. (Made by author)

f8ith · 2026-02-05T00:08:16Z

@Detanup01 the rumble should already work theoretically. My branch should now build correctly

About action_set_layers

Right now the action_set_layers is essentially stubbed. I don't see a point in implementing this fully since games seems to work fine now

utkarshdalal · 2026-02-05T12:27:46Z

@f8ith i think there are conflicts that would need to be resolved.

If you want to send me over the dlls (preferably for the experimental steamclient) I can test on a few games that aren't working currently!

Detanup01 · 2026-02-05T19:40:49Z

well need to fix conflicts but if you build in your end to windows x64 debug i appricite if you upload to anywhere currently MS suck ass with not supporting vs26 build yet so all my things on-hold and current dev env is fucked cus of it.

tlrd:
If you upload your build to anywhere i can download and test your stuff via custom script

f8ith · 2026-02-08T18:58:11Z

Published a debug x64 build at https://github.com/f8ith/gbe_fork/releases/tag/2026-02-08

Detanup01 · 2026-02-09T16:05:59Z

Real steam

vs
your gbe build

Basicly this, it isnt getting my controller whatever I do.

Code / call is basicly this
// steam ini & runcallback before calling any steam function.
Steam_Controller::Init() 1
Steam_Controller::GetConnectedControllers()
Steam_Controller::TriggerHapticPulse() // TODO
Steam_Controller::TriggerVibration() 10000 10000
Steam_Controller::Shutdown()

f8ith · 2026-02-09T17:47:39Z

Perhaps I unintentionally changed something when making the build after so long. Are the test scripts in the repo so that I can test it myself

utkarshdalal · 2026-02-17T04:47:37Z

Hi @f8ith any update here? happy to help out if needed. Just noticed you said it works with Elden Ring Nightreign which would be a big win for me!

f8ith · 2026-02-21T18:38:37Z

After rebasing again I'm getting errors from protobuf externs. Once I get it to build I can make my own tests, but fyi my build at June 2025 worked completely fine for me in Elden Ring: Nightreign on a stock Dualsense over USB + BT, not sure what changed between then and now or if it's an issue related to Xbox controllers.

utkarshdalal · 2026-02-21T19:02:11Z

Can I help somehow?

f8ith · 2026-02-24T00:08:55Z

Controller glyphs are entirely game dependent. Forcing a certain controller type is an entirely separate issue from what this PR is trying to achieve and generally requires mods

你需要的东西是游戏普丁，展示什么图案不关这软件的事

jesstech · 2026-04-29T02:21:06Z

Would love to see this get merged soon as the impending steam controller release should dramatically bump the number of users who will be relying on steam input, with the recognition that Valve is likely going to be making changes to the SIAPI related to things like haptic feedback (something they've acknowledged they're "looking into" for the steam controller which currently just transcribes basic/classic xinput rumble)

Detanup01 · 2026-04-29T08:31:28Z

I will be updating dependency and stuff for vs26 and stuff so i will include your changed deps too to be easier.
Will look into more the unimplemented / broken stuff .
Recommend resolving (again) this or next week be moving deps!

f8ith · 2026-05-12T17:16:29Z

Sorry for the lack of updates as I've been away from my main setup for a while, will be back to working on this next week hopefully

Detanup01 · 2026-05-15T15:17:21Z

SDL3 now on main!

utkarshdalal · 2026-05-15T15:18:53Z

Woohoo! Was this merged? Or implemented another way?

Detanup01 · 2026-05-16T14:40:58Z

No, i just added the dependency of sdl3 that this pr has into main to easier transition
