I'm having an issue with RetroArch. I've researched a lot about this before posting, but here I am since I can't find any solutions.

So the problem has been asked before, but that was 5 years ago and there was no definitive answer then, so I'm hoping there is now. I've read he whole LibRetro documentation page regarding inputs, yet nothing was mentioned about D-Input and X-Input and their features.

Now, I know when you connect a N64 compatible controller through a Raphnet converter (n64 to USB, V3), the signal is automatically D-Input no matter what. Everything's fine, the controller works on RetroArch but rumble function is off. When rumble is supposed to occur, I get frame-drops instead (if I select no Pak in the core options, there's no frame-drops).

I came to realise that RetroArch does NOT support rumble through D-Input. All the sources I found regarding this are 5+ years old though and the documentation mentions nothing. In the 5 years past, is there any progress in that regard? Or was RetroArch never supposed to support D-Input in the first place?

I know all about CRT Emudriver on Windows, but I'm in this rabbit hole for some days now and realised I can just use Linux and skip all that stuff and actually make the PC feel like an actual console! Problem is, I cannot find good information online on HOW to do it.

Since AI became a thing, googling became harder. I normally don't post, but guys I'm desperate. It's been DAYS of searching and all I got is confusion. And no, I don't trust AI - it just predicts what word comes next, it has no actual knowledge.

So my main questions are:

1. Since in Linux we're capable to do 15kHz out of the box, can I use integrated graphics on a powerful AMD CPU (like a Ryzen 5 5600G or something modern), or should I still use a dedicated, analogue, DVI-I card (like a Radeon R9 380. Same one would use on windows with CRT Emudriver)? Is integrated graphics going to introduce latency or something due to extra adaptors?
2. I have SCART input on the CRT. However, I want to use composite, not RGB nor component. Do I just do GPU (either DVI-I or HDMI, depends on the answer to question 1.) to VGA, VGA to composite, composite to SCART?

Everything is SO confusing. There's so much info for Windows with CRT Emudriver, but I don't know if I can apply some of that info to a Linux settup (adapters mostly). I don't know if I need specific adapters or if any would do. In my rabbit hole dive I came to websites like Lotharek's Lair which I still don't know what I would need that for. Please help!

EDIT: I'm in Europe, so I'm going to use a PAL CRT TV which has SCART input. I don't know if that matters, but in case it does, here is this info as well.
