Is it possible to use in an Android system TV box with USB port?
For what remote play?
I believe there's a Sony remote play app for Android devices (I have one on my cell phone) but I don't think anyone's used RP via Android device. It needs to be pc or PS4 or Mac.
Technically it could work on a rooted box but it's not my priority.
I use my android phone + USB-C Hub (Ethernet, USB-A port & Charge port) to use my XIM Apex on PS5 with a 3rd party remote play app.
Then you're the exception not the rule.
I like the idea but you have the know how & the savvy to do it. I do not.
I remember way back in the day before they cracked DS4 I bought a custom made contraption that connected to my xim, it was a modded DS4 with the guts ripped out and a USB port installed in the right trigger area.
Wonder if that thing still works.
