N64 planning rpi2

Libretro Lakka
#1

Hey guys,

I was wondering if n64 is planned on getting better emulation. The fellas at retropie are getting pretty good results (https://www.raspberrypi.org/emulation-on-raspberry-pi-2/) without overclocking the pi.

Thanks in advance for any feedback.

Do you know what gfx plugin they are using?

Anyway, Squarepusher is better placed than me to reply to that.

I am not sure but I saw this from two months ago: The emulators are: • the latest “stable” Mupen64 • Mupen64’s libretro core and • the “experimental” build of Mupen64 Each has its’ own quirks, and acts a little differently with some games. Also, there are 3 video plugins: • gles2n64 (aka video-N64) • Rice (aka video-Rice) and • glide64mk2 Generally the latest stable build of Mupen64 and the rice plugin produce the best results.

Any updates regarding this?

Not yet, the latest master of mupen, I’m not even able to cross compile it for arm anymore :frowning:

For me, Muppen64 works fine… I found out that the stock resolution of 640x480 is too high. The original N64 had a resolution of 320x240 for most games.

So if you change the resolution to 320x240 in the muppen64 configfile or the retroarch configfile for the muppen64 parts it will work fine. Well at least for me it does… i can run Mario64 and 007 GoldenEye 64 smooth at an average of 60 FPS.

Good luck!

Wah, I need to try this right now :o

And did you try? How is it working? Let me know, i am very curious if it also works for you :wink: If so i will place an How-to-manual on this forum (also if you need one of course)

Hi, I tried 3 things:

  • overclocking
  • reducing the RPi2 framebuffer to 640x480
  • reducing mupen64plus framebuffer to 320x240

Even the combination of those 3 things didn’t improve the performance enough to get Mario 64 full speed with the glide64 gfx pluggin.

that is strange…

So what is your fps in the lakka mainmenu? and what is it when you play mario64 (not in the intro because there is always some lag in the intro)? do you use memory split on your pi? an if so what size memory split do you use?

Dit you change the xorg.conf file to change the resolution or dit you use the lakka menu?

You might want to take a look at your power supply. Is it at least 5V and 2A? Is the USB cable high quality? If your Pi isn’t getting enough juice then it’ll run slower as a result.

Why modifying xorg.conf? Lakka doesn’t use Xorg at all on the RPi.

I will try with a better power supply. Thanks for the tip.
