Hey guys, need some help. How do you overwrite controls for a single emulator? I have tried editing the Retroarch config that is in the /opt/retropie/configs/pcengine folder, but have not had any success.
Basically my controller is set up fine for most systems, but in Pc Engine emulation it is mapping the 2 button to where Y is on the controller and the 1 button to where the B is on the controller. I want to map 2 to where A is on my controller, like a real PC engine controller.
My current config looks like the below and my install is using the Logitech Rumblepad 2 USB cfg file which is correctly set up.
#include "/opt/retropie/configs/all/retroarch.cfg"
# All settings made here will override the global settings for the current emulator core
input_remapping_directory = /opt/retropie/configs/pcengine/
video_shader = /opt/retropie/emulators/retroarch/shader/crt/crt-caligari.glsl
video_shader_enable = true
Figured this out, I will post it in case anyone else needs to fix the same issue. I started the pc engine emulator and went through the in game retropie options and reconfigured teh controls to fix the button. I saved that out as a new configuration, opened it up and copied out the button mapping commands inside that file and then just pasted them into the /configs/pcengine/retroarch.cfg file. So now buttons I and II are in the B and A slots on my controller like a NES/PC Engine controller.
