I got the Ultimarc BlueHID working after a fresh reinstall of the latest RetroPie 4.4. Which is great news, I can highly recommend this controller board with RetroPie!

@superrune I’m curious to know whether you can still connect & pair the the Ultramarc BlueHID device with Retropie ( if you’re still using either of course).

I’m using a fresh install of Retropie 4.7.1 and I’m having the same issue as you had in 2018 ie: “It connects through Bluetooth without any problems, but it seems like the Raspberry does not understand what I'm connecting”.

It appears in the list of available BT devices in the Retropie Bluetooth setup but it will not pair.
It will connect and work on my PC so it would appear the hardware is ok

I’d appreciate any thoughts or advice

@caver01 ok. I was lazy in my wording. It doesn't make me want to read it. It's obviously / hopefully the right log file.

@edmaul69

Nice. That's a great middle ground solution.

@sirhenrythe5th thank you will do.

@caver01 thanks again. I read a bit now and I think I understand the role of retroarch, acting as an interface between emulationstation and the various emulators.
That clears up a lot!
You are right about the shift function on my ipac too.
But I cannot end the Vice version on Retropie - even when using a keyboard. I need to open the vice menu (F12) and then navigate to "Quit vice".
But it's okay. For C64 emulation I find myself grabbing for the keyboard quite often.

Cheers,

Robin

@hamak Sweet! Thanks!
