Controller works in Emulation Station, MAME says it's configured, but it won't work (yes, I searched!)

According to the RetroPie Setup Script, on the first screen that comes up with that script, it's 4.8. (I realize I typed "4.4," in the first post, and that was a mistake. I knew it was 4.8, but had just read a web page talking about version 4.4 and that got stuck in my head.)

At this point, the only games I have on here are a few MAME ROMs.

A bit of background, which I didn't mention because it's on an older system. I'm setting this up for my wife's cousin, who's been through a hard time. I started on it over a year ago, the controllers worked, but I had some fine tuning to do. (That was long enough ago, I've forgotten what the issues were, but I remember I had basic functionality and could play games using these controllers.) I can't remember what versions of RetroPie or anything else was on that system. When I got back to it, last week, I just downloaded the latest image and started with it on the same Pi3B as before, but completely different install on a USB stick.

Also, the .zip files I'm using came from a working install (the arcade system I setup in 2020)

I tried searching for how to find the version for MAME. All I can find about that is that the window I get while the file is being unzipped and run lr-mame2003. I do have a subdirectory in mame-libretro that is "2003." However, when I copied these files from another system, they were just in the mame-libretro directory, not in the 2003 subdirectory.

Here's the log on Pastebin.

There are no obvious errors in the logs, doesn't seem like a RetroArch config issue. The mame2003 sub-folder is where the configs and nvram/hiscores are kept - if it's not there, it will be created on the first run of the core.

If there's not a issue with just the controller order (i.e. you're trying to use the P2 controller as P1 and it's not accepting the coin from P2, etc.), then I suggest you leave only the ROM files in the folder, to exclude any configurations you might have copied from your other systems. And also, run an update of the system/packages to get the latest versions of RetroArch/cores.

Wow! That's it - and I really am surprised. For reference, these are wireless controllers that have USB receivers that plug into the USB ports. I labelled the controllers and the receivers to keep them straight. When I set this up, I only set up the 1st controller. (Figured I'd get things going, then add other ROMs, setup the other controller, and so on.) Of course both controllers are the same, but I didn't think the other controller would work at all until I set it up as a 2nd controller.

What's happening that Controller 1 works with ES and Mame uses Controller 2? I figure there's some easy way to change the device info in a config file somewhere?

I'll be doing that. When I downloaded the latest image, I just jumped in and forgot to run an upgrade first. Then, while I was working on the issue, I wanted to restrict the variables I changed until I got it working.

You can use the Configuration Editor to switch the joystick order.

@mitu

Any clue about why this is happening? It wasn't an issue with that earlier version I was using and it's weird to see it show up out of the blue. Also, after reading the page you link to, it looks like I might have to reconfigure for every emulator I use, which could be both confusing and a pain.

mitu

Not sure 'what' exactly is happening ? You have 2 controllers, one is P1 and one is P2, but not in the order you expected.

You can set options for all libretro cores, as well for each one in particular.

What seems odd to me is that ES reads them in on order and the emulator reads them in another. (And I haven't even configured the 2nd one yet, but since it's identical, I can see why the same data works for the 2nd one when the emulator switches them.) Just on the curious side, I'm thinking that the two controllers look identical, no serial number or anything like that, so other than which USB port they're in, there's no way for anything to tell which one is which.

There's no 'order' of controllers in EmulationStation - every controller is treated the same, there's no P1 or P2 like in an emulator.

Ah - never tried the 2nd controller in ES. As I mentioned, I had not configured it, so I figured it would be just "dead" until I did - but, again, A and B controllers are identical.

This sounds like there's no need, then, to ever configure the 2nd controller, since ES sees both of them and treats them the same and the emulators (at least MAME) already sees it.

Or is there some reason I need to configure the 2nd one anyway?

No, just like RetroArch, the configuration is tied to the name/vendor/product values, which are identical for both controllers.

I want to add one point on this, that might be helpful.

Once I got this all working, I made a new image on another USB stick. Since I did several trial-and-error rounds on this, I want to create an image for myself that I can copy and use in case one version breaks or there are problems - and to give to friends who want to make their own retro gaming systems.

When I booted the new image, and hit F4 to get to the shell from EmulationStation, I got the normal multi-colored ASCII art image of the joy stick logo and info that RetroPie normally displays when you start a shell. I saw that and realized the other system was not doing that, so maybe something went wrong with creating the image or there were some other issues with it.

@Tango The welcome logo is installed by default on any image, but can be un-installed afterwards. It's a separate package that doesn't affect everything else.
