Restore Mame emulators to default keyboard settings

Floob

Try removing this file
/opt/retropie/configs/mame-libretro/cfg/default.cfg

@Floob Thanks Floob, I don't seem to have that file in there.

I just have:

content_history.lpl
emulators.cfg
retroarch.cfg

the only one with todays date alongside it is content_history - but that is 0 (zero) bytes in size?

Floob

Sorry - I meant in here:
/opt/retropie/configs/mame-mame4all/cfg

thedon

@Floob thanks again, that folder is there, but empty.

In the parent folder opt/retropie/configs/mame-mame4all - I do have:

emulators.cfg (dated Mar 2)
mame.cfg (dated Mar 2)
retroarch.cfg (dated today)

Floob

Sorry again - I read your post too quickly.
For libretro based emulators, your controller file is in /opt/retropie/configs/all/retroarch-joypads
You'll see your controller file in there.

Has anything changed in that file today?

You can read your mame-libretro retroarch.cfg override with
nano /opt/retropie/configs/mame-libretro/retroarch.cfg anything odd in there?

Are you running mame-2003 ? If so, you can find its default in
/home/pi/RetroPie/roms/mame-libretro/mame2003/cfg

If you want to paste your configs, please use pastebin.com

@Floob Yes, a couple of Changes:
ControlBlockGamepad.cfg
ControlBlockGamepad.cfg.bak

This seems to be the thing, as my arcade panel interface to the Pi is a ControlBlock - and within both files I can see button mappings. Oddly the "input_select_btn" = "10"

Is there something simple I can change this value too (do I just type "Enter" in the quotes instead of 10, to get me back able to edit the in-mame config menu?

Floob

Did you try deleting the default.cfg in here?
/home/pi/RetroPie/roms/mame-libretro/mame2003/cfg

To rewrite the controller file you mention above, you can just go into Emulation Station and press Start to bring up the Configure Controller option and re-run that process - it should overwrite/update your controller file.

@Floob Hmm maybe I'm getting lost here - in /home/pi/RetroPie/roms/mame-libretro/ I just see my game roms, the only folders are Artwork and Samples

Emulation Station seems to work fine - but are you saying redoing that setup will affect the separate button mappings in the Mame emulators?

Floob

@thedon If you run mame2003 it should create a folder in there called mame2003.
Are you running RetroPie 3.8 or a previous versions.

Re-running the controller setup in ES will just re-create the main controller files for RetroArch, not specific to MAME.
You could search for a default.cfg I guess sudo find / -name "default.cfg"

@Floob

Thanks Floob, I thought I was running version 3.8, but can't see it in any of the menu's / splash screen - where would I find it?

I ran the sudo find / -name "default.cfg" command, and there is one in home/pi/RetroPie/roms/config/default.cfg

I also tried the nano /opt/retropie/configs/mame-libretro/retroarch.cfg and tried to put a select button map in there. Whatever I've done (blindly) seems to have helped and I could restart and use select the libretro mame config menu, but not in advmame.

However, in my earlier attempts to update packages to try to fix the button mapping I've created two new problems -

(update - fixed, and no longer an issue, I removed the static IP allocation and it works again!) my WiFi adapter doesn't seem to work anymore (edit: it see's the SSID, but doesn't connect - I'm checking my router config / static IP allocation in case the problem is in there...)
the RetroPie menu in ES looks very different, and
in the libretro Mame config interface (pressing Tab when game is running), half way through setting the buttons, it starts to takes ESCAPE to be a button choice, rather than to clear the existing button mapping (by the way your

was one of the most helpful when I first set this up with a little usb gamepad to test the concept before i built my cabinet - it's brilliant, thank you).
