Hi. Im in the same boat as you, I have a great recalbox distro but I need the picadehat x to get installed, how exactly did you do it as the recalbox command line is very restrictive. I even copied over the install files and tried to run but it wont let me, and in logged in as root. Any info would be great ,thanks.
@substring Yeah, no problem, I just wanted to keep it at max anyway. I just thought that the games had no sound since one of my cables from my TV to my sound system had become unplugged. In-app volume settings are probably only necessary on hand-held/arcade devices anyway. Thanks for the help.
This topic is old, but as I have faced what I believe to be the same issue, and managed to SOLVE IT, I would like to share my solution with you.
I have had kind of the same issue, and never understood how it happened. The result/problem was that as soon as I touched the "right direction" button of my D-pad, or right direction of the Joystick of my arcade cabinet (my RaspberryPi is installed in an arcade cabinet), a Mame settings menu appeared on screen. Or, to be more precise and exact, the following settings bars would appear alternatively (depending on my pressing the "up" or "down" buttons, then) at the bottom of the screen, while I was still playing: "Gamma correction", "Volume", "Brightness", "Contrast", etc.
Here is how I have got rid of those annoying settings bars, although I confess I do not understand quite well why it works.
As I have said, my RasberryPi is inside an arcade cabinet, so I have to access it via "My Local Networks" in my Windows Explorer. The exact path I have followed is:
"My Local Networks/RECALBOX/Share/roms/mame/mame2003/cfg.
Once I arrived in that "cfg" folder, I noticed there was a ".cfg" file for each game that I had been playing (or simply tried) on Mame since I owned my arcade cabinet. I simply deleted all such .cfg files, went back in front of my arcade cabinet, launched a game, and miraculously it worked i.e. the annoying settings menu would no longer display when I would press the "right" direction on the D-pad, or joystick !!!
I hope this description will help those of you which have the same problem.
J'ai pas compris grand chose dans ce que tu as dis mais je te fais confiance...
Le volume en sortie de la prise casque doit être proche de celui de n'importe quel appareil qui a une prise casque (c'est le cas d'origine sur la MD de souvenir et c'est aussi ce que je voudrais pour ce projet).
Je voudrais déporter le GPIO (juste le nécessaire pour les contrôles arcade complets pour 2 joueurs) pour brancher de temps à autre la MD Pi dans une borne qui lui servira de dock.
En gros, si j'ai envie d'emmener ma Recalbox chez quelqu'un, je prend juste la console et la borne vide attendra sagement que le Pi revienne...
