Every day is a school day
Retro handhelds like the Anbernic RG35XX H are fantastic but if you’ve recently upgraded to a new version of the Knulli custom firmware and ran into Wi-Fi connectivity issues, so did I.
After some head-scratching, I remembered an experimental setting I enabled for Firefly:
wireless_hybrid_fix.Once disabled, the Wi-Fi connected straight away and has been stable since.
Anbernic RG35XX H with 8Bitdo SN30 Pro Bluetooth was a bit of trial and error but got an external controller configured with Knulli.
Power on the SN30 Pro in “Windows” mode (hold Y + Start) then hold the pairing button for 3s.
In Knulli, open the menu: Controller & Bluetooth Settings > Enable Bluetooth > Pair Bluetooth Pads Automatically.
Once detected, if the controller is not responsive then you’re in a mode other than Windows.
From Controller Mapping select OK on the warning then hold any key on the SN30 Pro. Configure the keys and set either the Function key as either Star or Home on the SN30 Pro.
You’ll need then to set the active controller to SN30 Pro as P1 (or P2) controller with Controller & Bluetooth Settings > P1.
It’s not perfect but more than good enough to play games with the device connected to HDMI, which is pretty handy for a short sighted old fart.
