Dope as video games and more. I set up all of my devices as best as possible and available from my store linked below. www.gotoretro.com/product/rg3...
This is EXACTLY what I was looking for, I'm genuinely mind blown because I couldn't find it until it just showed on my YT homepage. so What I'm basically trying to do is installing this custom firmware onto my RG35XX which should be arriving really soon, could you make a installation guide video on how to do that? I'm not really an expert..
Head to knulli.org to download the latest image file. Then use WinDisk32Imager or similar to flash the image file to your SD card. Pop the SD card in your device and boot it up. On first boot it will install itself.
I don't think you can as of yet , i'm using this on my H model and it's great , needs a few tweaks but nothing major. I think with the Plus model you have to reconfigure individual controls . My advise unless i'm wrong is stay with stock FW for the time being unless they announce that switching to analog is an option.
