@Efriim Thanks! Gonna give it a go.

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!

@roxton looks like it's supported. I found a relevant post on the lr-mupen64plus GitHub. https://github.com/libretro/mupen64plus-libretro/issues/16 There are instructions on there how to get it to work. Though whether it's still accurate or applies to a RPI setup I'm not sure.

@squishykoishi am not using hires version and in fact locked the screen res for N64 games at 720x576 this can add lag as you’re forcing your tv to do an up scaling operation. see https://github.com/RetroPie/RetroPie-Setup/wiki/Input-Lag#use-hdtvs-native-display-resolution retropie already runs (most) n64 games at 320x240 and then let’s SDL to a (fast) upscale using the GPU. the rest of the input lag wiki may help you if there’s still an issue. weird that gles2n64 etc fix the problem but they don’t have accurate emulation so may have incorrectly quick latency to start with? not sure

@Ashrill just be aware save states will not function when using omx as the audio plugin. Also the default volume is insanely loud and can't be adjusted as far as I know.

@rodrod66 Then please add more details about your system, as requested in https://retropie.org.uk/forum/topic/3/read-this-first. The gamepad configuration should modify the files in /opt/retropie/configs/n64/, can you post the InputAutoCfg.ini file on pastebin.com to take a look at it ?

The specific emulator I'm having trouble with is mupen64plus-glide64 the lr-mupen64plus works fine but looks awful and won't load high res textures. The mupen64plus-glide64 emulator worked great until I had to reinstall everything for other reasons. No system hardware has changed since I've started this.

I only did compilation, I have not tested the emulators yet!

@quicksilver Yeah I figured that out in the end thanks tho x

@Boa are you using the standalone mupen64plus or lr-mupen64plus?

@Heartless yeah that's what I figured. I suppose you could make changes to the mupen64plus.sh blacklist or one of the video plugin .ini files but that is a little above me.

@quicksilver That's true, that's the video I watched and yes it's innacurate. Thanks for the link. Is there any way to stretch the screen with mupen64plus ? Any way to change the resolution ?

@goobatroopa gles2n64 saves the day. Thank you very much for your assistance @quicksilver

@tr3v0r If you're just a beginner, then I suggest you use RGUI and the auto-configuration produced for RetroArch and don't edit any files. Use the 'Core input remapping' (see docs) to change the RetroPad controls.

@dankcushions thanks. Is there a way I can override the launch scripts?

I set my video mode, for standard mupen64plus, here. /opt/retropie/configs/n64 Open mupen64plus.cfg, scroll down to ... [Video-General] Fullscreen = True ScreenWidth = 320 ScreenHeight = 240 VerticalSync = False AspectRatio = True That is what I use for 240p on a CRT. On a LCD, change the screen size to whatever you want it to be. This works for all N64 games.
