Hi everyone. I have been searching in the forum and have read many threads but haven´t found the solution yet.
When trying to run N64 games the screen goes black but I can hear the sound. Info:
If I select the other available core I can see the image but it is too slow. I have also tested batocera with the same emulator+core just to double check if is something related to my PC but it worked correctly.
Does anyone have the same issue? Thank you
hi @pmroyo
please give me more information to pc Configuration .
I think the problem comes from the framebuffer you have an nvidia video card or something else?
Hi @strodown and thank you for your response. I am using an old laptop: intel core 2 duo t5500, 1gb RAM and integrated graphics. I suppose it is not a hardware issue because N64 games run perfect using batocera.
Do someone have the same problem? I haven´t found the solution yet
I'm pretty new to this but I'm also having this issue. I don't have much details for my specs at the moment but im using a little SFF computer with an i5 cpu, no GPU and booting/running off a 32gb usb. I really haven't done much troubleshooting as I'm an amateur with this stuff but would love to find out if there is an easy fix. 
@pmroyo I have the same problem and I have not found a solution. I hope someone shares the solution
Excuse me, but I have the same problem with n64.
Platform : rpi3., 6.1.1 dragon blaze.
Issue the same as in x86_64 platforms.
As I try to launch any game it goes back to ES.
Sometimes it gets black screen and nothing happens anymore.
I read a couple instructions, tried to change video modes, tried to change a couple of configs in recalbox.conf and mupen65plus. Nothing helped.
Controller : DS3 original. Any other platforms works fine. I'd like to mention the fact that the problem only when you use mupen64plus as a main emulator. Libretro plus mupen64 core works,but slow. It'd be nice if someone find a solution.
I have a similar/same issue (only now i seem to be making backward progress)
Platform :
Old model Dell Optiplex 755 with an core 2 cpu, no GPU and booting/running off a 32gb usb
6.1.1 dragon blaze. x86_64 (also had x86 running on it yesterday)
wired keyboard (but did not work with PowerA Mini xbox controler)
with a fresh install i can hear the game and navigate it, but not see anything. While i suspect that it might be the lack of a dedicated graphics card on an old machine, i followed this https://github.com/recalbox/recalbox-os/wiki/N64-%3A-return-to-ES-(EN) i had found in the readme int he rom folder. I was able to follow everything in the instructions (not the first time by any means) but the TV (and monitor) i have these connected to do not offer a list of options, like the write up suggest. so i am stuck with a higher than desired resolution without being able to change it.
Have tried the different cores as well.
Since messing around with it i am now unable to even get it to run (with black screen) it just boots me out.
Suggestions?
I feel like I changed the screen ratio and it helped before. I’m really new to this also and can’t confirm cause now my n64 games ain’t working either. 
Ok fixed it!!! Try...
setting the resolution to 4:3 ratio with Libretro for n64 games.
I have a optiplex 360 with a hdmi card adapter.

Glad you got it. I tried your suggestion, but did not make any difference for my set-up
