Hi,
I use Mame4all-pi for MAME roms with Retropie2.3 and emulationStation2 on piB+.

Mame Roms start correcly but excepted ‘Escape’ and ‘F3’ (reset game), my keyboard doesn’t “respond”.
I know to start game, I need to press ‘5’ or ‘6’ to insert coins. But because I use a french keyboard, the keys ‘5’ and ‘6’ are not available without SHIFT. So the game doesn’t know I want to play :(

-> I would like to configure keys to map to another ones.

With the other emulators, once they start, I can use the ‘F1’ key to configure input (ie:snes…). But it doesn’t work with Mame4all-pi.

In es_system.cfg file, I can read :
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 4 “/opt/retropie/emulators/mame4all-pi/mame %BASENAME%”</command>

In /opt/retropie/configs/mame :
the file retroarch.cfg is empty. Just it says “all settings made here will override the global settings for the current emulator core”

Inside /opt/retropie/emulators/mame4all-pi/mame.cfg I can read keyboard config but without information about ‘insert coins’. Only information about 1player config (and nothing about player#2 config too).

-> I don’t know where I can change keys in a config file.
-> Do you know the name and location of this file ?

Then I have started manually mame (program) in /opt/retropie/emulators/mame4all-pi, I have started a rom and I have pressed TAB. In the menu I have changed some keys and the ‘5’ and ‘6’. It WORKS.

Now I would like to backup my configuration. Does someone know which file I need to backup ? (and how to check my own configuration (key-map) in the defined file?)

Thx for your help.
Patrick.
