@MANMAKRO said in Handheld console issue:
Can someone please recommend me some good controllers that register as one controller on retropie and can have a left one and right one.
You don't need registered controllers. You can create your own with a 3D printer if you want. You can copy what I did but for a wired controller if you want a fully personalized project.
You can use a teensyLC.
To program it, see on Google . With this, I created the equivalent of a PS3 controller for my handheld (including R3 and L3).
see: https://www.pjrc.com/teensy/td_joystick.html (It's a good start)
Here is my code for my .ino file (inspired by Pi Ultra project but with more buttons and some tweaks in the code for deadzone and speed response )
/* Buttons to USB Joystick Example
You must select Joystick from the "Tools > USB Type" menu
This example code is in the public domain.

You can also use a PS4 controller if you want a separate controller.
