PCXS-ReARMed – PSX roms – Sound is slow

[patrick500]

Hi
I use PCSX-ReARMed version 1.9 (June 20 2014) with emulationstation to run PSX roms.
I have added BIOS and it’s loaded without error.
Games start without issue, but after 1 min I have trouble regarding sound.
The sound is ‘lagging’ or is played very slow.
Sometimes, when the music or the voice are shutdown during a few seconds, the sound restarts normally. But after a short moment it begins again to be slow.

When the game is loading, I have no particular error. (‘selected sound output driver : libretro’)
I have tried with or without Bios and the problem seems to not be linked. I have the same ‘sound speed’.
I observe the same thing whatever the used roms.

Have you met the same trouble?
How I can solve it?

Thanks a lot for your help.
Patrick.

I can’t help you with yours question, but where should i place the Bios files?

Hi
about the bios, I have changed in the file :
/opt/retropie/configs/all/retroarch.cfg
the following parameter : System_directory
System_directory = /home/pi/RetroPie/roms/BIOS
With this parameter, all bios files are stored in this specific folder, for ALL emulators.

The bios files for PSX are :
SCPH1000.bin
SCPH1001.bin
SCPH7003.bin

Now when you start a PSX game, the message ‘bios not found – bugs excepted…’ is removed.

Hi, just tried to overlock my Raspberry Pi to

arm_freq=1000
gpu_mem=384
avoid_safe_mode=1
core_freq=450
sdram_freq=500
over_voltage=4
force_turbo=0

I have no sound errors in Dino Crisis 2 now :) I think you need heatsinks and a fan to make this work without freezes

Thanks the bios worked!.. but i had to lowercase scph…. .bin and …roms/bios

Hi Downup,
My previous config was :
arm_freq=900
core_freq=250
sdram_freq=450
over_voltage=2
-> The sound was slow.

Now I use :
arm_freq=1050
gpu_mem=384
avoid_safe_mode=1
overscan=1
core_freq=500
sdram_freq=550
over_voltage=6
and it seems to be better regarding the sound (but may be not perfect). I test with Mortal Kombat II.

I have followed information about overclocking from here :
https://github.com/retropie/RetroPie-Setup/wiki/Advanced-Configuration
Of course I have got heatsinks but no fan.
I have not yet tested the provided script from the link to check the temperature… I will do it.

Nice, went with raspberry standard 1000mhz overclocking. Been playing dino crisis 2 now for 2hours runs smooth!

Will build a case for my pi. But this is my setup :P
