MAME Force Feedback plugin support in RetroArch?

[ArsInvictus]

I’m setting up a racing cab right now and I have been trying to figure out how to enable force feedback in some of the MAME titles like Rush. There is a plugin for MAME available, but it requires that you drop the files into a MAME install directory and configure it there, which I don’t think would work with the RetroArch cores?

This is the plugin I am looking into: https://github.com/Boomslangnz/FFBArcadePlugin

Does anyone have any guidance on how to get this to work? I’d much prefer to use @HyperspaceMadness’s shader with these games but I’d also miss not having force feedback.

Thanks!

You could probably use WindowCast to grab the output of the standalone mame and push it through the shader pipeline.

Official release thread for WindowCast core

WindowCast for Libretro (formerly WGC Window Capture) Libretro core to capture the contents of another window for video processing. This is useful, for say, capturing the output of a standalone emulator (like xemu, Dolphin standalone, RPCS3 or PCSX2 nightlies) or a PC game running in a window and then processing it with RetroArch’s shader stack. Here’s an example of the core in action, capturing Dead Cells (image courtesy of HyperspaceMadness). [MegaBezel-deadcells1] Download I plan to event…

@Duimon might have some idea of the plugin thing.

Yeah, MAME games (All games actually.) have to be hardcoded in work, I would be very surprised if the RA core dll gave the same output as the standalone dll, but maybe.

I think getting it to work would involve using the mame ini files. I’ll see what I can figure out.

Thanks @Duimon, if you have any updates on it let me know!

If I had to choose force feedback vs the shader I’d probably take the shader, I spent a ton of time getting these games looking amazing and it just doesn’t look right in the cab without the reflective bezel effects. But I’d love to have FFB too! I can mess around with WindowCast as another option later, but I think it would introduce some latency

WindowCast currently introduces 1 frame of latency which seems to be unnoticeable to the people who have tested it thus far.

@IHQMD has been working on methods to remove even this latency by not having to copy the image and use it more directly, but that’s still being developed.

Yeah 1 frame won’t be noticeable for me, not in a driving game for sure, so I can give that approach a shot, thank you!
