How to use Overclock and Mupen Core Options to significantly increase 64 game playability, quality, and stability

dankcushions

@Twitch0815 those options are only for the the libretro (lr-) verison of the core, not the standalone. the standalone should have equivalent options but none of them will have the exact same name in mupen64plus.cfg. they'll be something different.

mupen64plus.cfg is auto-populated with all the default options when you run a game on standalone so you can just tweak what's already there.

Great post I had already tried overclocking mine but this just gives me a few more things to modify thanks!

Great post, the play looks great. I will be trying the N64 emulator again with these new tweaks. Have you tried Castlevania? The last time I played around with it the opening screen had some "tiling" problems and the transparent overlay to choose your character was black. Game play had some lag.

Just to verify the options settings above are for the lr version and not the standalone?

HEy Guys, does this also works wih the Pi 2 B+?!?

Hello,

I have test your configuration today.
It's look good for a lot of rom, but I always have a realy bad sound with Wave Race.

Have you do something for this? Or it's just on my Pi?

I'm using a raspberry PI 3, with retropie 3.6 (install with a SD-card image)

If someone has an idea... :)

@Riverstorm
Did you try the 4 diff emulator plugins via run command
I remember trying ti once did not seem bad at all I can mess around with a bit i am working with hi res texture packs right now releasing another video shortly.

The hardware overclocks are for any raspi 3

The tweaks above in the file apply to libretro version but for the life of me even though it sould seem ti improve performance on mupen64plus
So if you see that same thing let me know something that I am trying to determine if it is a placebo effect or not.

Ill update everyone as I finish my tweaking.

The hardware overclock would not work on a pi2.
If you check https://github.com/retropie/retropie-setup/wiki/Overclocking the first top half details settings and steps to modify your pi 2

But if you want results like in the video you are going to need a pi 3.

Overclocking a 2 can get some games to work but not as well or as many as the pi 3.

@Hyell
Have you tried hitting x and switching to a few different plugins?

What overclock settings are you using?

Hyell

@Twitch0815
Hello,

Yes I have try different plugins. It's a little better with Gles2 but not as good as your video ^^.

I use the same overclocking setting as you. I will testing other setting today and I will see if I can get a good results :)

Where did you get your case? I see you have some standoffs on the bottom plate so you have enough room to add a heatsink. The bottom is the memory chip and the top of the Pi is the GPU?

Just search around on amazon

The 2 chips on the top are the CPU the bigger one and the USB/Nic Controlling chip
Bottom chip is the shared memory GPU
As I understand.

Thanks Twitch, I appreciate the link. I like the looks of that "case". I will get one ordered today. Looking forward to your next video.

Hello,

Wave race sound still working bad for me.
Maybe a connectivity problem or just my old TV...

In another style, I test 1080° and it's great.
Just a little overclock setting :
arm_freq=1300
over_voltage=6
temp_limit=80
core_freq=500

and use Glide.
I don't see this game on your video, you can have a lot of fun with it :)

Twitch0815

@Hyell

Try adding these two
gpu_mem=450
v3d_freq=500
and make sure wave rice is using glide and resolution

you can see how it is running on my setup in this video

Starting around the 1 minute mark
Both stock and with the high res texture package enabled

Hyell

Thanks,
I will test it tonight :)

thanks for that. I got also a Pi3 but nt configured right now. I want just to solve the MarioKart 64 Sound issue on the pi2. everytime when the sound scrap the game is also a little bit stocking...and that sucks

@Twitch0815
I just test, and it's really better, thank you very much :)

@Twitch0815 yet another awesome post making all of this optimisation stuff easier for Luddites like me - thanks a lot Twitch - have been travelling recently but looking to try out your PSP settings tonight and will report back.

Really looking forward to the dreamcast post too!!

Prindle19

Wow, really nice performance boost!

How do you get the hotkeys working in mupen64plus without running the libreto / retroarch config'ed version?

(For exit, save, load state, etc.?)

Stay tuned to separate videos on Dreamcast, NDS, and PSP

@Twitch0815 Lookin' forward to NDS and PSP, I have a ton of games yet to be finished on those. Would be a blast to play em on a Pi output to the big screen.
