Auto 1 Auto 2, etc. in RetroArch

Can I put this in a place where ES can't overwrite it?

If you don't re-configure the gamepad, ES will not overwrite it. You can also choose to not auto-generate these configus from ES - there's an option in the Configuration/Tools for the emulationstation package that does that.

Is that what a core input remap does?

Yes, I would suggest to use that if you need remaping only for the Megadrive/Genesis system.

If so, do I just plop my changes into PicoDrive.rmp? If so, do I need to include all the inputs or just the changes? (i.e. input_x_btn = "4" and input_r_btn = "2")

Just do it from the RGUI - https://retropie.org.uk/docs/RetroArch-Configuration/#core-input-remapping - and it will be fine.

But the way the lines are defined inside retroarch I can’t tell what it is exactly I am modifying. I see that I can change the button that corresponds to but when it’s prefaced with auto I have no idea what that means. Can you give me an example based upon the lines I gave you at the beginning of this thread?

Please re-read my first reply in the topic.

Auto: 1 (N/A), (Key: z) [User 1] B

I apologize sincerely. I still don’t understand.

The line I quoted above doesn’t really give me any indication where B is on my controller. So I understand how I can change the mapping by cycling through the options but what am I changing and to where? I suppose I could iterate each change. Look where B is now—which is the right flipper in Sonic Spinball—make a change, then see where it goes on the controller. I can then do the same for the other buttons.

Is this what you’re referring to when you ask me to reread the response? There’s a another item in there about remapping on ES and I can do that, but I think I’m stuck with the same issue. I can’t see what the items to the left in the mapping means in order to change it.

I’m sorry I’m not understanding it. Please be a little more patient because I will get it. :-)

@mitu Oh... wait. I think I see what you mean.

I'm going to try some things and report back.

N/A means the input doesn't have a label (normal)

So if I remember correctly, retroarch used to show button labels and then at some point when retroarch got updated (maybe a year or two ago?) The control menu was a bit different and the labels were missing. At one point I found a forum post that showed how to add the labels back in. I think it was @pjft that posted it but unfortunately I can't find that post anywhere.

The good news! I'm an idiot.

The bad news! I'm an idiot.

What I wasn't connecting is the number to the corresponding joystick button. That information really isn't anywhere in the Monster Joystick manuals. After reading a bit about remapping on the RetroPie page, I used the jstest program to find the number values of all the buttons. I then was able to figure that, for example, when 1 was listed in the RGUI, it maps to joystick button 1 which is the lower left of all group of six buttons on the Monster.

I still made a couple of mistake rearranging things, but it's all done now and I have a six button Genesis controller setup for the core. Yay!!

That's okay. If you come across it, please let me know!

Ooh! Time to make another backup!!

@quicksilver That looks good. I may do that.

Glancing at that message, it also points to a repo of various cfg files that might help.

But... is it saying that the labels will be matched up via autoconfig if there's a corresponding device entry available? For instance, my device is called (eg) "SNES GamePad." If RetroArch is aware of SNES GamePad, it'll automatically apply the labels?

Doesn't really matter. I can do it manually.

Thanks for sending the link!

Yes, it will load the autoconfiguration file and apply the labels. Here's an example (taken from here):

@mitu

It sounds like there's some kind of library of controllers that Retroarch knows about? Is that pulled from the Internet or does a group of them exist inside the Retropie installation?

I guess what I'm getting at here is: If I were adventurous, could I create my own autoconfigure entry for my particular controller since it doesn't match up with anything currently in there? I don't plan to do this. It's a curiosity.

Another question: Let's say I want to get an N64-style controller. Is there a way for me to look up whether a particular mfg's controller exists inside RetroArch's known controllers so that wouldn't need to manually remap?

Thanks!

Yes, at the link I posted previousy - https://github.com/libretro/retroarch-joypad-autoconfig

Neither. When you configure your gamepad in EmulationStation, an auto-config file is generated automatically by RetroPie and copied into the right place, so it's loaded by each libretro core (RetroArch).

I guess what I'm getting at here is: If I were adventurous, could I create my own autoconfigure entry for my particular controller since it doesn't match up with anything currently in there? I don't plan to do this. It's a curiosity.

Yes, you can - https://docs.libretro.com/guides/joypad-autoconfiguration/ - but, as I said, an auto-configuration is generated for your when you configure your gamepad in EmulationStation, so you don't have to.

Another question: Let's say I want to get an N64-style controller. Is there a way for me to look up whether a particular mfg's controller exists inside RetroArch's known controllers so that wouldn't need to manually remap?

You can look it up in the RetroArch's joypad repository - link posted above.
