N64 Mario Kart, how's yours?

[cyborguk]

Hello,

Has anyone got Mario Kart of the n64, running smoothly? If so can you share your settings?

Also how do you change the shaders? I did read you need to set a hot key, but I’m not sure where or how I set this.

Thanks in advance for your time.

[dankcushions]

runs pretty fine for me at 1080p – even 4 player! some slowdown on some stages (eg the desert one with the train), but it’s makes the sound stutter more than affect the gameplay, really.

i use the mupen64plus emulator (NOT the retroarch version, which seems worse for me). the sound seems to have a slight amount of latency, but i’ve never managed to get to the bottom of that.

i don’t use shaders since it’s running at a native 1080p – it looks really crisp.

[cyborguk]

What do you mean you don’t use the Retroarch one? I hit the X key on start and I have 4 emulators to choose from:

Ir-Mupen64plus
Mupen64plus-gles2n64
Mupen64plus-glesrice
Mupen64plusGLideN64

Ir-Mupen64plus is the only one that plays sound, the other don’t but play smooth. At the start of Mario Kart the Nintendo logo comes up and spins with the sound of a car, but the sound is awful, hows yours?

Retropi 3.2.1

[dankcushions]

Ir-Mupen64plus is the retroarch one. i’m pretty sure i use Mupen64plus-gles2n64 (gles2n64 is the graphics plugin). I don’t remember the sound being awful but i’ll try it tonight and post my config file :) i seem to remmeber it takes AGES to load, though.

[cyborguk]

Yeah no sound at all for some reason. Thanks by the way.

Cyborguk, if you still have sound issues you might be using an analog headphone output instead of HDMI sound? If so then in the mupen64plus config file you need to change the output port to 0.the setting is near the top of the file.

I have Mario kart running well on my arcade system, not 100% but very close. Here is a picture of my cab.

wow that arcade cabinet is so nice!! amazing job!
