N64 : return to ES (EN)

Subs edited this page Oct 20, 2017 · 8 revisions

Mupen64plus is not auto-configured by recalbox as the other emulators. So you need to do it manually.

The N64 video mode is set in your recalbox.conf file.
By default, we are using the video mode : n64.videomode=DMT 4 HDMI

This mode display a resolution of 640x480.
We defined this resolution by default, because RPI2 can't emulate N64 at a higher resolution with a good framerate.
So 640x480 is the resolution max to use on recalbox.

Warning: if your screen can't change resolution (ex: official Pi touchscreen), you'll have black borders around the picture as it won't be stretched to fit the screen. In such case, you need to set n64.videomode=default and edit /recalbox/share/system/configs/mupen64/mupen64plus.cfg to change the output resolution to the native one of your screen (here 800x480):

[Video-General]
# Use fullscreen mode if True, or windowed mode if False
Fullscreen = False
# Width of output window or fullscreen width
ScreenWidth = 800
# Height of output window or fullscreen height
ScreenHeight = 480

But, every screens don't have the same video mode compatibility.
So, when you try to start a N64 game, you may have a black screen with a return to Emulationstation.
In this case, you must determine which video modes are compatible with your own screen.


Get a root access, then type these 2 commands :

tvservice -m DMT

and

tvservice -m CEA


Commands will return something like that:
[root@RECALBOX ~]# tvservice -m DMT
Group DMT has 16 modes:
           mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive 
           mode 5: 640x480 @ 72Hz 4:3, clock:31MHz progressive 
           mode 6: 640x480 @ 75Hz 4:3, clock:31MHz progressive 
           mode 8: 800x600 @ 56Hz 4:3, clock:36MHz progressive 
           mode 9: 800x600 @ 60Hz 4:3, clock:40MHz progressive 
           mode 10: 800x600 @ 72Hz 4:3, clock:50MHz progressive 
           mode 11: 800x600 @ 75Hz 4:3, clock:49MHz progressive 
           mode 16: 1024x768 @ 60Hz 4:3, clock:65MHz progressive 
           mode 17: 1024x768 @ 70Hz 4:3, clock:75MHz progressive 
           mode 18: 1024x768 @ 75Hz 4:3, clock:78MHz progressive 
           mode 21: 1152x864 @ 75Hz 4:3, clock:108MHz progressive 
           mode 32: 1280x960 @ 60Hz 4:3, clock:108MHz progressive 
           mode 35: 1280x1024 @ 60Hz 5:4, clock:108MHz progressive 
           mode 36: 1280x1024 @ 75Hz 5:4, clock:135MHz progressive 
  (prefer) mode 57: 1680x1050 @ 60Hz 16:10, clock:119MHz progressive 
           mode 58: 1680x1050 @ 60Hz 16:10, clock:146MHz progressive 

and

[root@RECALBOX ~]# tvservice -m CEA
Group CEA has 5 modes:
           mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive 
           mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive 
           mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive 
  (native) mode 4: 1280x720 @ 60Hz 16:9, clock:74MHz progressive 
           mode 16: 1920x1080 @ 60Hz 16:9, clock:148MHz progressive 

Ok now we have all video modes which can be used on this monitor.
We have to find a video mode, with a resolution equal or below to 640x480, then define this mode in the recalbox.conf file.

If I choose this video mode :

Group CEA has 5 modes:
           mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive

I'll edit my recalbox.conf file like this :

  • video mode by default : n64.videomode=DMT 4 HDMI
  • new video mode : n64.videomode=CEA 1 HDMI

###Particular case : CRT screen
If you are using a CRT screen, you must edit your video mode like this :
n64.videomode=default
