[Question] How to fix games that lag.

Post by Francis » Fri Aug 05, 2016 2:41 pm

Hello, guys. Currently I'm gathering the hardware needed to make the GBZ. I was going to try to fit a Raspberry pi 3 in, but now I found a video that some games that i wanted to play, namely Conker's bad fur day, are not playable in using the Raspberry pi 3.

Is there anything i can do about it? Is there any other computer that i can use to run all these games flawlessly?

Have you tried using a different emulator? (Press any button at the very beginning of game launch) or a different rom source?

I have not. I'm still gathering the necessary hardware in order to start my build. I read your non-oem build--looks awesome! I feel your pain regarding school and work. I'm currently doing research and finishing my last year in engineering school. By any chance, have you played that game on your build?

/off-topic you finishing your bachelor or grad? That's a good program to be in.

I have not. What system is it on and I'll see if I have it and will report back how it does and on which emulator.

@wermy I remember talking about overclocking the pi in another thread. Can you pretty please tell us your settings so that this man can play games more smoothly? :) (for pi 3 and zero?)

I don't remember exactly what settings I used, but all I did was add an entry for arm_freq in the config.txt, as outlined here: https://www.raspberrypi.org/documentati ... fig-txt.md

There are other things you can mess with as well like gpu_freq, core_freq and sdram_freq, but all I was brave enough to mess with was arm_freq. :)

I haven't found an iso to test it yet, but the biggest complication is trying to play an N64 game on the RPi0. It is just a little too intense for the hardware, but if you're really interested in it, I've heard the RPi3 has had success playing N64 games.

The only game I've heard that is playable on the N64 is MarioKart.

Thanks, wermy. I'll check it out!

This specific game for some reason doesn't run well even on the Pi3. I'm currently looking at other computer options, but they are either too big or too expensive. I'll keep y'all posted.

If you want to optimize for N64
check out my video.

https://www.youtube.com/watch?v=YZM1hIZSnfU
I also wrote
https://github.com/retropie/retropie-se ... tendo%2064

Been meaning to update rewrite as things have changed with updates.

Currently for optimized N64 performance what you want to do is start out with 4.0 RC 1 (Important because it has tweaks built just for 64 that 3.8 does not)
Launch Retropie Setup
Update the setup script
Go to manage packages
Manage main packages
update mupen64 plus


Throw on an overclock

arm_freq=1350
over_voltage=6
temp_limit=80
core_freq=500

h264_freq=333
avoid_pwm_pll=1
v3d_freq=500

#Ram Overclock
sdram_freq=588
sdram_schmoo=0x02000020
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4

most important of the overclocks is the v3d_freq for N64 performance.

Put your roms in the directory.
Set Glide as your default emulator by pressing x when the game launches.


Now test your favorite games most should play pretty well if something is laggy then try a different emulator on a per rom basis
Do this by pressing x when it starts up
select default emulator for rom and change to a different emulator and test.
