@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.

@mitu I have the exact issue and can post my ini if you like. I have a separate topic in the Help section I posted yesterday if you want the details.

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

@soraroxas please fill out https://retropie.org.uk/forum/topic/3/read-this-first

@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.

I found this thread that seems to contain the answer: https://retropie.org.uk/forum/topic/17650/dualshock-controllers-on-4-4-with-3b/35
