New N64 mupen64plus graphics plugin optimised for Pis.

Not had a chance to check this out, but sounds very promising. i know the existing semi-optimised gles2n64 plugin works great, but has limited compatibility. This seems to share the compatibility problems (at least, so far), but should be even faster. Very interesting!

Is there an easy way to add this plugin to the mupen64 installed with Retropie to test it out?

[gizmo98]

It is a little bit faster but has more glitches as any other plugin. It has more compatibility issues as glesn64. But it dös Notaz Crash your Pi of you run Zelda games. ( But colors are wrong)

I’ll take a run at scripting it.

Gizmo, I tried building from your repo but it looks like you’ve changed things quite a bit from upstream such as the Makefile being moved and now it apparently requires the Mupen64plus api files to be somewhere? Can you give me a step by step on how to compile from your fork?

[gizmo98]

I will post an experimental retropie module this weekend.

@zerojay
Try this:
Close emulationstation with F4 and type…

mkdir test
cd test
git clone --depth=1 -b mupen64plus-videocore https://github.com/gizmo98/RetroPie-Setup.git
cd RetroPie-Setup
sudo ./retropie_packages.sh mupen64plus
emulationstation

Limitations:
-Only runs good if output res is Full HD
-Kills console keyboard input. Only important if you close emulationstation or want to use launch menu.

I followed the above and it causes emulationstation not to launch due to not having permissions to /root/RetroPie/roms/n64. Why? Well, because of this in es_systems.cfg:

<system>
<name>n64</name>
<fullname>Nintendo 64</fullname>
<path>/root/RetroPie/roms/n64</path> ************
<extension>.z64 .n64 .v64 .Z64 .N64 .V64</extension>
<command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ n64 %ROM%</command>
<platform>n64</platform>
<theme>n64</theme>
<directlaunch/>
</system>

You probably want to fix that.

[gizmo98]

Interesting. Please try a source based installation over retropie_setup.sh. Even though this should only happen if you run retropie_packages.sh as user root. You could also rename this line by hand:
wrong
<path>/root/RetroPie/roms/n64</path>
right
<path>/home/pi/RetroPie/roms/n64</path>

[zerojay]

I did edit the line to get it working. As far as I know, retropie_packages.sh is only supposed to be run as root anyways…? I know it’s definitely the case with retropie_setup.sh. Not too sure how that happened but… *shrug*

I’m reimaging my setup and I’ll take another try at it and test more than 2 or 3 games on it.

[gizmo98]

Does it run?

[zerojay]

It ran for me. I didn’t test it much though.

Hi guys, I also installed the video plugin as per gizmo98’s instructions and when I rebooted emulationstation it was there, so I guess everything worked in the installation.

However, when I choose videocore as the video mode, Mario Kart switches to 320×240 mode regardless of what CEA mode I choose. The speed is great, but there are also a few artefacts in the game. When choosing characters their backgrounds are not exactly right, and when playing the power-ups are very squished and also the drivers are completely black.

Is there any way to change the render resolution?
