lr-mame2003 thinks I'm pushing all the buttons at the same time

[mahoneyt944]

@andrew632 lr-mame2003 is restored.

[Mercury]

Thanks for all the feedback. Like I said, updating lr-mame2003 was okay, it doesn't break until I actually update Retroarch.

The problem also seems to affect lr-snes9x2010, I press jump in Super Mario World and Mario heads in all kinds of directions as if I was pressing several things at once. My understanding is that the fact the emulator's name starts with lr means it also relies on Retroarch/Libretro, yes?

I don't think I have any controller remaps. I'm wondering whether I need to configure the controllers via the Retroarch interface, although I'm not sure how. The Retroarch system information lists identical details for all three zero day encoders, so I'm not sure why two are misbehaving. The problem occurs when I'm in the RetroArch menus - the Button 1 behaves as if I've moved the joystick - but it behaves correctly in the EmulationStation menus.

Could it be because the two misbehaving encoders use a 5-pin cable for the joystick and something in the Retroarch update doesn't like that? As a test I unplugged that 5-pin cable, but Mario's jump button still behaves as if I'm also using the joystick.

Alternatively, maybe I could generate new custom profiles for the zero delay encoders. Again, not sure how to do that but the default Dragon profile works fine with one of the encoders.

With the update I'm running Retroarch 1.8.8, is there an easier way to install earlier versions so I can test them? Otherwise. It looks like I need to get deep under the bonnet to control how Retroarch interprets what's coming from the controllers. Suggestions?

[dankcushions]

i wouldn't map via retroarch at all. libretro control maps are fundamental parts of retropie and if they're not working right in all lr- emulators, something is seriously wrong.

in the first instance i would provide a verbose log of mario (mame has other complexities), as per https://retropie.org.uk/forum/topic/3/read-this-first. this should prove whether any other overrides are present.

assuming there are none, i would reset the contorller config via https://retropie.org.uk/forum/topic/5069/resetting-controller-configuration - when you reboot emulationstation it will prompt you to rebind, and then everything should be back to normal.

Here is a verbose log of Super Mario World in lr-snes9x2010. I can't see anything obviously wrong here, but I'm a bit out of my depth

[dankcushions]

@Mercury seems fine to me. did you try resetting?

[Mercury]

@dankcushions said in lr-mame2003 thinks I'm pushing all the buttons at the same time:

i would reset the contorller config

I tried that, set up the joystick and buttons in EmulationStation when it rebooted and launched 1942 in lr-mame2003, but the problem persists. It's very strange, when I do a reset the default in lr-mame2003 is for the Fire button to open the MAME menu (as if you've pressed the TAB key). For some reason, under "Input (general)" it says Config Menu is set to "TAB or RetroPad1 R2".

When I reset this just using the TAB key on the keyboard, it says "TAB RetroPad1 R2", which is strange, I think it should just say TAB. Now I can play 1942, but when I press Fire the joystick stops responding for a moment, so I stop moving. If I go back into the Input (general) settings and map the Fire button to an unused command like "8 Players Start", it thinks I've pressed the joystick in all four directions and pressed A, B and X.

Meanwhile over in Super Mario World, the jump button still misbehaves like it's sending multiple commands.

As a test, I went through the EmulationStation reset process again but I plugged my 4-way Sudo Happ into that player 1 encoder - using 4 2-pin cables rather than 1 5-pin cable. I did the EmulationStation reset and went through the steps. The problem didn't go away, so maybe the issue isn't related to how the joystick is connected to the encoder.

For another test, I went through the EmulationStation reset process and then used 4-way Sudo Happ in the player 3 encoder to set up EmulationStation. Now it works properly and pressing the Fire button registers just as RetroPad3 A. One strange thing is that left and right are backwards and it didn't remember what the player 1, 2 and coin buttons did. Is there something else I also need to reset when I reset EmulationStation? It remembers those things for encoder 1 after an EmulationStation reset,

like i said, the problem is fundamental if it's happening across all libretro emulators, so there's no point configuring MAME separately - that will only introduce more problems.

if you've been messing with MAME menus then i would delete default.cfg and any game-name.cfgs as per https://retropie.org.uk/docs/lr-mame2003/#mame-menu

[Mercury]

@dankcushions thanks, I tried the emulationstation reset and deleting all those mame.cfg files but it didn't fix the problem.

Even when I do all that, go through the EmulationStation set up and then launch 1942 in lr-mame2003, under "Input (general)" it already says Config Menu is set to "TAB or RetroPad1 R2". Pressing Fire causes the Config Menu to open, I guess it thinks I've pressed RetroPad1 R2. Like I said, at this point if map the Fire button to an unused command like "8 Players Start", it thinks I've pressed the joystick in all four directions and pressed A, B and X.

Is there anywhere else that it might be remembering settings? Could it be something out of place in my /opt/retropie/configs/all/retroarch.cfg file - some misconfiguration which wasn't an issue before but upsets the latest version of RetroArch. Configuring this file has always made my like hell, it's possible I've screwed something up.

As I test I just tried replacing that retroarch.cfg with the default retroarch.cfg.rp-dist and it's fixed the problem! Now the button presses register as one button. Obviously there was some mistake on my part that RetroArch didn't care about until I updated. Here's what I had, can you see where I went wrong so I can avoid making the same mistake again?

@mitu sorry, it's here: https://pastebin.com/fZYh6usY

I think the issue is that I've configured both the "keyboard" input and the "Input device" buttons section. When I comment out the "Input device" buttons section, pressing the Fire button is recognised as a single button press.

Now I'm having trouble getting MAME to recognise all the buttons when I try to set it up, so I'm thinking I need to reset EmulationStation, delete the mame default.cfg file and set it all up again from scratch. Will that do the trick, or am I still missing something?

[Mercury]

So I set up my 3 joysticks in Emulation Station and launched 1942 in lr-mame2003 but it's not recognising the other buttons plugged into the encoders ie player1, player 2, coin 1. I'm guessing that's why I set up the "Input device" buttons section.

How do I fix it without breaking it again? Right now my retroarch.cfg file is a copy of retroarch.cfg.rp-dist so it looks like this: https://pastebin.com/8sQm1Krf

[Mercury]

SUCCESS - it looks like I've fixed it. The problem was that I hadn't commented out the unused buttons in the "Input device" buttons section of retroarch.cfg. Before I updated RetroArch didn't care, now it obviously does.

So I rolled back, updated and then only made that change to the retroarch.cfg. Everything else still works as before, because I didn't need to reset EmulationStation or MAME cfg files.

In the end it was a simple fix, thanks to everyone for all their feedback which helped me find the solution. Hopefully this thread helps someone else down the track.
