You could go into the MAME GUI and try to remap keys, but the layers of controls and remapping can get pretty confusing! In other words, it's possible to have the retropad mapped in the retroarch.cfg file and have that be in direct conflict with the actual raw keypress that is setup inside MAME2003. That's why you see both a key and a retropad referenced in the MAME GUI (in game menu brought up with ) when you are remapping in there. mame2003 and possibly other lr emulators accept inputs via the "virtual" retropad controllers, but it ALSO SIMULTANEOUSLY accepts raw keyboard inputs.

Like you said, mine prior was recognized prior as 2 controllers: Bonus Tip if you need to play RetroPie on a VGA monitor, which you will if you are building your Pi into an arcade cabinet, you need one simple bit of kit to accomplish this. Now there is NOTHING in the prior 2 folders. Then wipe and install the new RetroPie on your CD card and use File Manager to copy the folders back to the RetroPie directory. If you don't have anything in the former location, it means that RetroArch's cofiguration is not generated after you configure the joystick. This is where the EmulationStation stores the configuration. Now with Retro Pi 4.6 it stores the input data here: EmulationStation doesn't store its input configuration file here. This is the RetroArch auto-configuration folder, they're both pointing to the same location (one is a symlink of the other). Said in Rpi 4 with Retro Pi 4.6 Driver issue:
