Most consoles emulators games are now slow, help please !!

[darthlink]

So beside putting back my previous backup, does anyone have any idear to help me solve that problem please ?

[TMNTturtlguy]

@darthlink I am afraid there are just to many variables for us to be able to help you with an unknown problem and no other information except poor performance. If you could specify an error code, or specific issue we could trouble shoot, but the fact that all we know is your games started to run slow does not help us much. Before doing a full restore of your last backup, you could try to update all your packages from the retropie startup menu. Also confirm you are using a 2.5A power supply. that is about it all i can help with given the information you have provided.

[darthlink]

• 2.5A micro usb power supply: yes
• raspberrypi 4.9.24-v7 : with uname -a
• 256MB : for gpu
• error messages: none ( unles in a log file that i dont know of )
• uptaded all packages: done
• apt-get dist-upgrade : done ( already the newest version)
• apt-get update : done
• OS: Raspbian with pixel ( installed manually without noob )
• emulationstation also installed manually after raspbian with pixel
• command: free -h ( mem = 733M total and 562M used and 170M free )
• the raspberry pi 3 board is inside the closed black box with 2 heat sink that came with it

i have just tested all other emulators ( nes, snes, genesis, mastersystem, playstation, gameboy advance, psp ) i have not tested ( megadrive, game boy color, neo geo, sega 32x, N64 ). i already know that N64 are unplayable yet.

they all worked ok beside PSP witch little big planet is sort of playable, still slow but playable and sound is still crapy and lego star wars is still unplayable. SNES did shut down 1 game that i tested but it may be the rom, i will have to test other game too on snes.

The 2 psp roms where played directly from the microsd since i have copy them there to test earlier

[darthlink]

i have just manage to copy the log file from /dev/shm/runcommand.log so here it is, hope it can help:

From my quick look at the info you posted, I am wondering what is taking up all your memory, was the pi sitting idle when you ran free -h?

As for your description, since everything else is running ok, this sound normal to me. PSP is very hard to run, as is N64. What you are experiencing is nothing new to anyone, and most would report the same findings as you. I can't explain why you were able to run little big planet previously. In order to run PSP and N64 you probably nee to run an overclock.

I also just saw that you posted you are running the pi in a black box with 2 heat sinks. Typically if you are not overclocking, you won't need a fan, however if you are placing the pi in a small black box, and maxing out the system by running N64 and PSP games, it is very possible that at some point you over heated the Pi, i am just speculating on what might have cause your performance to dip.

Everything said, your system sounds to be runnning normally if all the other emulators are playing at normal speeds.

[TMNTturtlguy]

@darthlink Those are all memory errors. Your build is out of memory. As i just posted above, something on your pi is eating up a lot of memory, and when you are trying to run a high consumption emulator like PSP and N64 you are getting memory errors.

ok thanks, i did not know this was memory errors.

i have just went into retroarch directly from emulationstation setings and went into video driver and i can see that it is using the GL driver but there are also sdl2 and vg and dispmanx, does any other driver could work better the GL maybe ?

[TMNTturtlguy]

@darthlink i would search the forums. I think it depends on your setup and if you are using hdmi or another output. I have seen a lot of info on dispmanx, but i have never had issues and never tried to change it. Hopefully someone else can help on this. When i get my pi running i am going to check what i have for memory when in idle, and compare to yours. Again though, i would read up on PSP and N64.

[darthlink]

is there any way for me that i could copy the video settings from retroarch and paste them here ? Maybe my video settings are not ok or too high somehow cause i know i have changed some setting like the aspect ration and bilinary filtering. is that all in a file somewhere ?

[darthlink]

i have just found the file retroarch.cfg but it is very long, how can i make it here in a scrolling box please ? like someone did to my config.txt file earlier in that post ?

[TMNTturtlguy]

@darthlink Ok, so it sounds like you are not running a standard setup and you have made modifications, i was under the understanding you hadn't modified anything except your memory split. At this point you are past my level of knowledge so I will need to step away and let others help. I suggest you describe what settings you have changed instead of posting a very long file that not many people will want to look through to try to find what you did.

To answer your question on how to format posts, please read the forum rules for more information. here is a direct link to formatting, the forum rules also give links to pastebin. link

[darthlink]

well all i had changed in retroarch video config was the aspect ration to have full screen mode and the turning on the bilinary filter but i have put it back off.

Thx for the help and info ;)

command: free -h ( mem = 733M total and 562M used and 170M free )

Ok, i am running my pi and i have a very heavy theme running. My free -h tells me

 Mem:  733M total 358M used 374M free 5.2M shared 25M buffered  157M cached

I switched to carbon which is a very light theme and i get:

 Mem:  733M total 311M used 422M free 5.2M shared 26M buffered  158M cached

As i suggested earlier, something is running on your pi that is eating up your memory.

[darthlink]

I have change the aspect ratio to windowed and now my memory went down to:

use= 267M

i think i will have to look a little more into this. I have tried Little Big planet and it seem to run a little better ( or i am just imagining this loll ) but lego star wars still unplayable

Is there a way to just revert to retroarch.cfg file to default ?

also i will have to test other games on psp because maybe lego star wars does noit run well on emulation so i will look for a list of psp games that run good on emulationstation with lr-ppsspp and maybe that will help i guest.

[TMNTturtlguy]

@darthlink no psp run well on the pi unless you overclock.

It was runing perfectly not long ago and my friend has raspbien but without pixel and he can play pretty well psp roms. he does not overclock.

he does know much about linux command too so he cant help me much loll unfortunatelly

[darthlink]

its getting late and need to go to bed, working tomorow morning loll.

thx a hole lot for your help TMNTturtlguy

i will make more test tomorow and kepp you up to date ;)

[darthlink]

here is the result of the command free -h when emulationstation is not running

         total       used       free     shared    buffers     cached

Mem: 733M 112M 620M 5.2M 14M 59M
-/+ buffers/cache: 38M 694M
Swap: 99M 0B 99M

[darthlink]

i have just went and renamed the file retroarch.cfg to retroarch.bak then rebooted then went into retroarch directly from emulationstation and it created a new retroarch.cfg file. There is a new background ( maybe from my packages updates yesterday ) in retroarch, it look exactly like the PS4 default background loll with the wave and all.

so i tried little big planet a 10 second cause i have to leave to work now but it seemed the same, still crappy audio and a little laggy.

I will search for a list today and try that.

so now my retroarch.cfg is back to default.
