Thanks Florian :-)

Today I solved the problem with an older RetroPie-script and used the commands manually:

cd /home/pi/RetroPie/emulatorcores/

git clone git://github.com/libretro/Genesis-Plus-GX.git

cd Genesis-Plus-GX

make -f Makefile.libretro
And then just change the command-line in es_systems.cfg and the Mastersystem roms working great! :-)

I’ve fixed my problem.

I changed the commands in the es_systems.cfg. So that I use the Genesis-Plus Emulator for the Mastersystem and the Megadrive roms.

Now there’s sound over HDMI on all my Emulators (Gamegear, Mastersystem, Megadrive, NES, SNES). Before I changed the megadrive emulator I coulden’t execute the roms when watching Video over  Composite. This problem fixed also with changing the emulator to Genesis-Plus.

Here is the command-line that must be changed in es_systems.cfg:

Gamegear:

old -> COMMAND=/home/pi/RetroPie/emulators/osmose-0.8.1+rpi20121122/osmose %ROM% -joy -tv -fs

Sega Master System II:

old -> COMMAND=/home/pi/RetroPie/emulators/osmose-0.8.1+rpi20121122/osmose %ROM% -joy -tv -fs

Sega Megadrive:

old -> COMMAND=dgen -f %ROM%

Change these three lines with the new COMMAND-line:

COMMAND=retroarch -L /home/pi/RetroPie/emulatorcores/Genesis-Plus-GX/libretro.so %ROM%

The Genesis-Plus Core is already installed on the sd card.

My sound problem is solved! :-)

Now I have to change the resolution with the help of the script in this link http://angrynerd.flimmerkiste.com/?p=23

to get clearer sound for megadrive and snes roms…

I’ve already tried following options in the /home/pi/RetroPie/configs/mastersystem/retroarch.cfg

audio_enable=true

audio_out_rate=44100

audio_driver=sdl

 

But it doesn’t work.

Hi,

I had the same problem. Sound only over RCA with Video over Composite. But no sound over HDMI.

The solution is to add a line in the config.txt which is located in /boot/config.txt

I edit the file over another linux PC. There you’ll see two partitions when inserting the sd card. The small one includes the config.txt. Just open the config.txt with gedit or something like that and uncomment the following line:

hdmi_drive = 2

This option forces the HDMI mode. It’s necessary if some TV’s or monitors wants to use the DVI mode but there’s no sound over DVI. So when you force the HDMI mode it doesn’t matter which TV or monitor you use.

It works great with sega megadrive, nes, snes emulators.

But I’ve still a problem with gamegear and sega mastersystem roms. Both use the osmose emulator and with this there’s still no sound.

Can anyone help me with the solution for the osmose emulator and HDMI sound??
