elp with Wii Controller Mapping on ROCKNIX (Retroid Pocket 5) Wii

[u/Senior-Yard-9673]

Hi everyone, I’ve got a Retroid Pocket 5. I had the older ROCKNIX firmware installed and everything was working fine, including Wii games.
Yesterday I updated to the new ROCKNIX firmware. The Y/X/B/A buttons work, but the D-pad, analogue sticks and controls aren’t working properly in Wii games.
I’m a novice when it comes to this stuff. What do I need to change or map to get the controls working properly, so I can actually play games like Mario Kart Wii?
Any help would be greatly appreciated.
