if people want more info on these devices, russ from retro game corps does a ton of reviews on them, from the cheapest (that are less than 30 euro) to the really expensive ones (600+!).
i myself own a retroid pocket 5, one trimui brick (which my wife adores) and a steam deck (yes, it's an amazing retro gaming machine).
(retro catalog also has a ton of technical information, including ratings)
Thanks for the share... been using a Beelink SER8 for about 6 months or so with Chimera, which has been mostly okay... I have to reset audio out to hdmi each boot and a couple other niggles with the Bluetooth controllers. May need to switch to ones that use custom/proprietary USB dongles with lower latency.
Hi there! I'm running the exact same setup and have encountered the same issues.
I have a little bash script [1] which I run on startup to fix the HDMI audio issue. I haven't got crontab working yet so I ssh in and run it manually.
I've tried 3 different controllers and ended up buying the 8bitDo ultimate as it supports 2.4g as well as Bluetooth. Also purchased a separate Bluetooth dongle and a usb extension cable to keep it away from any interference from the Beelink. Still have major issues with connectivity over a reasonably short distance (3-4m) in either mode.
Love the SER8 though, it's a great little machine and is well priced when on offer.
Had been looking at a one of the same controllers, using two over 2.4g with their dongle(s). May reset the whole thing when I do... have had trouble with the second connected controller always being controller 1, that I can't seem to fix.
+1 for Retro Game Corps, not only are his videos well made and informative he puts together guides for everything from basic retroarch configuration to how to install alternative OSes for specific devices (and why you might want to do that).
