I had a very similar problem to this thread. I replaced my Pi 3 retropie with a Pi 4 and retropie was behaving in a jittery fashion with Emulation Station and the games weren't smooth. I also have a 4K Samsung Smart TV as did the original poster. Although I wasn't using Amiberry, I was using mame, daphne, and jzintv and I figured the same solution that @gordonfreemanjr used would work for me. So I added the five lines to my /boot/config.txt file that he listed in his "IT WORKS" post but lo-and-behold it did not work for me. tvservice -s was still showing a 4K connection when I expected 1080p.
My solution was simple with a twist. Starting from the stock config.txt, I uncommented and modified the following:
It was necessary for me to add the :0 to get it to work. Now there are no jitters, the motion is smooth, and tvservice -s reports a 1080p connection.
@pieterken without being familiar with the software we can't really say but retropie sits on top of raspbian, so anything that runs as a background process/daemon (which is what i assume 'domoticz' is) should still be running.
From reading that, some games work ok, but many others are not likely to run well enough to enjoy playing them. Running Dolphin is a pretty big job for a Pi 4.
EDIT: As development continues on the various drivers and even Raspberry Pi OS 64-bit, this situation could improve. But keep in mind many of these things are outside of the control of the RetroPie project.
@thegreatmikeo good to know about the Xbox one controller thank you 🙏🙏
Based on a few YouTube videos, it appears 8bitdo controllers do work with iOS when adding the controller using the accessibility settings.
However, I’m not sure if that method has downsides over the regular Bluetooth device recognition.
In case it helps someone else, here’s a review of the 8bitdo working with iOS. The video creator explains how to add the controller with the accessibility method.
EDIT: samsh5fe titlescreen is still 'Samurai Showdown V Special', maybe it's not the 'perfect edition'.
Fullname of samsh5fe is "Samurai Shodown V Special (Final Edition, location test version)", it is indeed what some people refer to as "Perfect Edition". The word "Perfect" feels kinda counterfeit though, afaik they simply removed some gameplay elements from "Samurai Shodown V Special" (probably making the game more casual in the process) to make room for a story mode.
Except if you are using a non-merged romset, you'll probably need its parent samsh5sp.
From what I understand the "Perfect" edition of the game is an emulator that runs the "Special" edition, and overlays it with new content. It isn't a self-contained ROM.
To be more precise, the commercial emulator from "Samurai Shodown Collection" uses some quirks to replace the title screen and to add an english translation to the story mode. FBNeo use the raw romset and doesn't have any of those quirks.
