So it's a libretro core? Can't you just map it in the Retroarch menu (hotkey+X -> controls -> port 1 controls), or do I misunderstand?

The hotkey is defined in the RetroPie controller config. You can then customize the hotkeys in RetroArch.

Or I believe you can set up "shift key" behavior in the I-PAC config to do the same thing.

If you still want separate buttons that's fine, was just a personal preference to have my controls be minimal.

I haven't installed any leaf buttons/sticks myself, I guess you can check the other forums here or google around for more info.

@mitu That's how I originally started out and it didn't work. I have weeks of work into this image now and don't want to wipe it out on a whim until I know that every avenue has been explored. And as I said earlier, it's happening on multiple different images.

@gtbfilms Bummer. The loss of shader was definitely a result of swapping out old for new configs. You can add a shader configuration line like I did above in the all/retroarch.cfg or like I did in the arcade config folder.

As for sound, I would be surprised if Retroarch configs are to blame for that, especially since it still worked in lr-mame2003.

@backstander Nice. :)

Now all I have to do is get my Pi back to where it was before I broke Sudoers and see if I can actually get the retroarch.cfg files to save and work properly. Almost forgot that's what this thread was originally about.
