Issue with wrong buttons in lr-* emulators

[mark2472]

Note: I figured out how to fix this by manually editing config files, but I still have a question... why are lr-* emulators adding +3 to all buttons? Since I had it typed out, I figured I'd go ahead and post in case it helps anyone and also in case it's a bug that needs reported/fixed etc.

I'm having trouble with my bluetooth controller in all of the lr-* emulators (specifically tried lr-pcsx-rearmed, lr-snes9x2010, lr-fceumm, lr-picodrive, and more). I've spent hours googling, searching docs, searching forums, fiddling with config menus, fiddling directly with config files, starting over and going through the below steps multiple times in various different ways.

Anyway, here's the issue:
After getting the bluetooth controller connected and configured, it works great in menus and works fine in mupen64 (just not the lr one). Game controls work, hotkeys work, everything seems fine. But... when I go to any of the lr emulators, the controls are messed up. The hotkeys are wrong and the buttons are mapped wrong. For instance, R1 (instead of select) appears to be the hotkey enable button. So... R1 + random buttons does things like exit the game, save states, load states, etc. R1 + L2 (instead of start + select) exits the game. It's not just the hotkeys, though, all of the buttons are incorrect for gameplay as well.

I finally discovered that R1 + A opens the retroarch menu. From here, I was able to navigate this menu using keyboard arrows, z, and x. I can manually set the controls here in Settings>Input>User 1 Binds. All of the buttons seem to be +3 from what they were in EmulationStation. For instance, the A button in ES and in jstest is 0, but in RetroArch in an lr-* emulator it is 3. Select is 10 in ES/jstest, but 13 in the RetroArch menu. This is the case for all buttons on the controller.

This took me all day yesterday to figure out, and now I can at least get everything working... albeit by manually configuring all /opt/retropie/configs/{lr-* based emulators}/retroarch.cfg to +3 on all buttons.

Why are all of the buttons +3 in RetroArch in lr-* emulators? Is there a way to get RetroArch and/or libretro to not +3 all buttons?

Steps:

1. Followed https://github.com/RetroPie/RetroPie-Setup/wiki/First-Installation using keyboard
2. Connected bluetooth controller.
3. sudo nano /etc/udev/rules.d/55-local.rules and set files contents to:
   SUBSYSTEM=="input", ATTRS{name}=="BBC-GAME", MODE="0666", ENV{ID_INPUT_JOYSTICK}="1"
   per https://www.amazon.com/gp/customer-reviews/R3GVRHP307ROSX/ref=cm_cr_arp_d_rvw_ttl?ie=UTF8&ASIN=B01N8WWOE5
4. Added a few roms for several systems
5. Reboot, Main Menu => Configure Input and configured bluetooth controller
6. Issue is present but controller works for ES and config menus.
7. RetroPie Config => RetroPie Setup => Update RetroPie-Setup Script
8. Update => Yes to update installed packages => Yes to update underlying OS packages
9. Issue still persists

You should be able to re-configure the button mappings in one place. There should be a controller configuration file in /opt/retropie/configs/all/retroarch/autoconfig/ where you can change the input codes, instead of modifying each system's retroarch.cfg file.
As for why the mapping differ, maybe posting the es_input.cfg file from $HOME/.emulationstation could offer a clue to why the mapping is different.

Did you ever get this sorted or is manually adjusting al the lr config files the way to go?

[i2b5k0]

Actually, you can't even manually change the config file. It seems that jstest & emulationsation interpret one button as "0" but retroarch interprets that same button as "3". So yeah, you can fix button 10 by changing the config file to say "7" but retroarch doesn't like buttons to have negative numbers assigned so this doesn't work as a long term solution.

Many will say "buy a different controller." The Amazon is so far away. Also, the cost-benefit analysis of using a pi and retropie compared to buying something like the Allcade was that I wouldn't be needlessly buying things that I already had!
