@mitu Thanks to another thread of yours I have found the solution. https://retropie.org.uk/forum/topic/17492/retropie-4-4-and-tronsmart-mars-g02-with-wireless-dongle-problem The issue was that the controller by default comes recognized as a X mode (Xbox), I had to change it to D-mode (Android) by pressing 5 seconds the button home. After that joydev inmediately recognized it as Sharwan model. Once again, thaks a lot for your help.

Thank you for the reply. Before I saw you replied I tried reinstalling the drivers using the method you so happened to post in the thread I linked at the top. That worked for me. I will say I installed drivers 340 instead of 440 so that could of been my issue. For anyone that runs into this problem in the future here is a guide to install Nvidia drivers the way mitu recommended in this thread.

One reason the roms don't show up could be the Option "Parse Gamelists Only" in Emulation Station's Main Menu -> Other Settings (Screenshot). It should be set to OFF to see every zip file in the rom directories in Emulation station. If they will run, however, depends on the correct rom/emulator combination, see https://retropie.org.uk/docs/Arcade/.

Have done now. Its giving me no errors. Guess I will just have to reinstall and see if that fixes it. Thanks for your help.

One error i have, but for me is not urgent to resolve yet. i think is a dev thing enter to xmb retroarch menu, then resume... this freezing the retroarch menu, also with rgui

@mitu I can confirm: downgrading SDL to v2.0.8 solved my problem! Thanks for the help, as always. :-)

@BuZz Haha no worries mate! Thanks for the help!

@Thorr69 @Parabolaralus Ok, thanks for the help and info!

I think I found the solution. In mupen64plus.cfg you can find the overscan options. Need some fiddling around with it but probably this is what I was searching for. Though I don't know why the standard resolution (640x480) doesn't need overscan and higher resolutions need this to be able to fill the whole screen. Any one know why?

@mitu Quick update. Changing line 447 in /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh fixed my problem. I have changed pulse to alsa. Further more I've created a simple script, named n64audio to run at start/boot. In this script: #!/bin/sh sed -i 's/pulse/alsa/g' /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh Made the script executable sudo chmod +x n64audio After that sudo crontab -e And added the line @reboot /home/retropie/n64audio Now after every reboot pulse will be changed to alsa in the file /opt/retropie/emulators/mupen64plus/bin/mupen64plus.sh , if the line pulse exists. So if I update RetroPie and mupen64plus gets updated and overwrites my file (and put pulse back in to play) it will be overwritten on the next reboot. Again, thanks for all your help!

@Zore I don't see any errors in the log file. Can you also post the contents of ~/.emulationstation/es_input.cfg ? Check the permissions on that file also, if your user is able to write to it.

@mitu Thanks for the help. I will try install opengl drivers and try launch game again. If the probled will be solved , i type about this
