So I'm assuming this one? https://www.newfrog.com/product/usb-c-type-c-to-hdmi-hdtv-adapter-cable-for-nintendo-switch-game-console-196840 How long have you been using it as I've heard bad things about using these type of adapters on the Switch.
I have them both and recommend the Mayflash because you can change the controls and the right analog control feels more accurate compared to the 8bitdo.
I'll never understand why people have such a problem with controllers using AA batteries instead when you have the ability to buy rechargable ones that last longer and can be replaced compared to controllers with built in batteries like the Playstation controllers. I can't even use my PS4...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
