Homebrew Question Can I have N64 games running a full speed?

Keylogger · Mar 5, 2019

I am running retroarch 1.7.6 on atmosphere 0.8.4 with full ram access (https://gbatemp.net/threads/use-atmosphere-to-access-full-ram-with-homebrews-without-nsp.521240/)

I am running with max perf OC but even with this, N64 roms won't run at fullspeed.
Super Smash bros 64 and pokemon stadium runs at ~12fps
Zelda MM is slow when enter a new place
and more games that are slow in gameplay

Im using mupen64Plus-Next core

Try OC more when docked, but I would wait for N64 emulation to be perfected

Make sure you are using this specific build. Put this into /retroarch/cores/
https://m4xw.net/nextcloud/index.php/s/n87e8ycGGgfTM6L

Make sure Threaded Video is enabled in Video settings, and the audio driver is set to switch_thread in Drivers.

In core options, disable ‘Color buffer to DRAM’, ‘Depth Buffer to DRAM’ and ‘Crop mode’.

Ok thanks, i'll try with these settings

what more does this core have compared to official?

It's official, also makes use of the JIT patches.
Waiting for libnx over here before we get it on the nightlies ¯\_(ツ)_/¯

Hi m4xw, I used to use you config file that I found uploaded somewhere prior to mupen-next being implemented in retroarch, however my sd died so I decided to upgrade card and retroarch.
As I no longer have the config file and it worked so smoothly I was curious as to whether you are able to upload your new config file somewhere.

Thanks and keep up the good work, many people appreciate what you do

I'm using the latest stable. I don't have a threaded video option in the video driver settings. My only options are "gl", "switch", and "null".

Edit: nevermind. I found it. I'm an idiot. However, these settings didn't seem to help much. Even with a max overclock, I still get graphical glitches and serious slowdowns in Smash 64, Diddy Kong Racing, Ocarina of Time, and Mario Kart 64. However, Mario 64 plays almost perfectly.

Are you using the mupen-next core with dynamic recompiler?

Work off this checklist.

This is my setup:

Working great and I have played hours of 64 goodness.

I'm using Atmosphere with title redirection. I'm using the proper core (Mupen64-Next). I'm also using the latest version of Hekate. All of that is right. I have never used SX OS, even though I bought the SX Pro. I use it explicitly to boot external payloads. (Hekate, which then boots Atmosphere/Kosmos)

I am using exactly the version of Mupen that you linked here: https://m4xw.net/nextcloud/index.php/s/n87e8ycGGgfTM6L

Yet I still see FPS in the low 20s and sometimes teens even with docked CPU overclock. I just don't get it.

Hey i tried downloading that file but when I click the link it says file not found, any update to that core or somewhere else to download it? Thanks i know this thread is outdated.

for n64 make sure you are using retroarch nro installed, not the xci rom.

and n64 you have to try different plugins and change settings for each game, but i can confirm majoras mask can play at near full seed, the odd audio glitch and slight slow down if opening doors and entering a new location but it soon resumes near full speed.

The latest core can be downloaded within Retroarch or by downloading latest nightly build, core is mupen64Plus-Next

awesome thank you for the quick reply, overclocking still needed for smooth frame rates?

i wouldnt advise on over clocking, this will put strain on the console as games will still run slow if it cant run.

alter settings and resolution to optimise speed

Yeah I agree but didn't know what other options I had, would you happen to have a potential guide or link that I can follow for optimal settings for n64 retroarch on switch

For n64 because its still early days each game will be different, some no matter what you change will run like shit.

Its best to let it do a cfg for each game but its really trial and error.

Best bet, dont apply any graphic filters like sharp or hq filters, set resolution to 720 i think i had majoras running at.

In some cases youll have to exit reteoarch and go back in to see the changes apply.

Make sure also for n64 that its the installed version and also different n64 cores work better for some games than others.

The fuck are you saying, early days?
hah, I can count on 1 hand which games currently arent playable on switch that are playable on pc.
Everything in mupen next is max. a few weeks out of date.

Dont use anything but mupen next if you don't want to play some ancient hack.
Simple as that.

Theres loads that have issues like this guy is asking how to improve one.

Switch n64 emulation is far from pc quality, which even today is not flawless.

I advise the op to kindly listen to me and and this angry guy.

You will find games run nice, loads will run slow, you will need to change cores, settings but please never over clock.

Your putting strain on your console to try make a rom run better that is highly likely going to run like shit regardless.

Ive been part of the emulation scene back in the 90s and these cores are basic ports of pc plugins and dont always port over perfectly, retroarch is a program made to work on multiple devices.

The cores and plugins are all to work within retroarch and each device and hardware can cause issues, they dont make a plugin or core dedicated to just one device.

What in the world is this non sense?
I have almost my entire N64 library playing full speed without overclock. Stock speeds.
Only game I have which requires OC is Pokemon Snap. Everything else runs fullspeed at stock speeds, and even at 2x or higher resolutions.
