I guess the processor needs to be an Amlogic for the best media experience?
If you want to use CoreELEC, yes. It only supports Amlogic.
They also support flashing a lot of different TV android boxes and some can be had for cheap so also worth looking there.
I mean that depends on who does the port, in this case it's Nixxes so the port should be pretty good.
If Iron Galaxy does any more of the PS ports I won't even touch it for free.
CoreELEC is especially built with Amlogic chips in mind, it includes all the drivers necessary to GPU decode all codecs it can.
The live test you posted runs on CPU, there's no mobile ARM chip out there that can smoothly CPU decode anything above 1080p so using GPU decode is crucial.
That depends on the SBC.
Most of them boot from SD so you will want to get an enterprise SD card or one for cameras.
The Odroids have an eMMC slot for storage. Most boot from USB as well.
There are now SBC with SATA ports and even some with M.2 or PCI-e slots.
They use Samsung Exynos CPUs IIRC instead of the Broadcom chips that the Pis use
Didn't know there were Odroids with Exynos CPUs.
The N2+ has an Amlogic S922X, CoreELEC is also a fork of LibreELEC but only for Amlogic processors.
There are newer Amlogic chips nowadays but I never looked into them.
I have been using a Odroid N2+ running CoreELEC with the Jellyfin plugin ever since it released. Plays absolutely everything you throw at it, even 4k60 with HDR.
If you need Dolby Vision, you will need one of the supported devices, the Odroid N2+ is not one of them.
I never used Citra before so I just grabbed it from Flathub.
You can still grab the latest early access build here: https://github.com/pineappleEA/pineapple-src/releases
I don't think the PS3 has a UHD drive (or can output 4k).
If you already have a PC the cheapest way would be to get one of the 4k drives that can be flashed (https://forum.makemkv.com/forum/viewtopic.php?t=19634)
You can then either rip your blu-rays via MakeMKV directly or play them in VLC/Kodi via libmmbd.

MakeMKV is available on Linux as Flatpak and works out of the box: https://flathub.org/apps/com.makemkv.MakeMKV
Bulk Rename Utility
Probably a tough one since most people will use the command line to bulk rename files. I do use ChatGPT sometimes to create rename commands for me that are more complicated.
Exact Audio Copy
I use Sound Juicer now, used fre:ac before.

Logitech G Hub I know OpenRGB exists, and it’s good enough for my needs when it comes to LED management, but it doesn’t seem to be able to control DPI presets like G Hub.
Piper can do DPI presets: https://flathub.org/apps/org.freedesktop.Piper
Mp3tag
I used Mp3tag on Windows and switched to Picard, I like it even more than Mp3tag now: https://flathub.org/apps/org.musicbrainz.Picard
Paint.NET
Is GIMP really that complex for this use case? I use GIMP to do simple stuff like paint, rescale images, blur things, fill things, ... https://flathub.org/apps/org.gimp.GIMP
Playnite
I don't use anything out of Steam often but If you don't like Lutris, maybe Heroic for GOG and Epic? https://flathub.org/apps/com.heroicgameslauncher.hgl
Mod Organizer 2
r2modman has native support for Linux: https://github.com/ebkr/r2modmanPlus
There's also support for one-click installation of Mod Organizer 2 with steamtinkerlaunch: https://github.com/sonic2kk/steamtinkerlaunch/wiki/Mod-Organizer-2
I really wish Proton would start jumping on, at least in the experimental builds.
Currently they lack Wayland support altogether.
