    Hello,

    I’m trying to get a game on the PS1 working and I get the message “No BIOS found, expect errors” when I try to run it.

    I have added the BIOS files to /home/pi/RetroPie/BIOS like I do for the other emulators.

    The main one I have added is SCPH1001.BIN

    Any ideas why it isn’t seeing the BIOS file?

    Also tried this

    pi@raspberry ~ $ cd /opt/retropie/configs/psx
    pi@raspberry /opt/retropie/configs/psx $ nano retroarch.cfg
    Added the following line to the bottom of this file:

    system_directory= /home/pi/RetroPie/BIOS

    long shot, but are you sure it’s “RetroPie” ? on my system it’s lowercase. i imagine it’s all case sensitive as per the rest of the operating system.

    (ignore this, mine is RetroPie also!)

    I think it should be lowercase.

    Check the checksum also

    if it works lowercase then please do update the wiki page https://github.com/RetroPie/RetroPie-Setup/wiki/Playstation-1

    Did you compare the checksum ?

    Sorry I missed that part, I’ve just looked at the link but can’t see how I verify the checksum, how do I check it’s the right checksum?

    Google “how to checksum a file md5” or something – if on windows there are gui tools. on terminal on linux you can use “md5sum [file]”

    Checksum is fine.

    Just defaults to the HLE BIOS.

    It’s as if Retroarch isn’t even looking the BIOS folder for these files. Is the path set somewhere as I can’t see it in the Retroarch.cfg?

    Can you confirm you are using RetroPie 3.1 (or 3.2 or other) from the image provided on this site, as opposed to a source or binary install? Then I’ll do the same test and check it out.

    I’m using 3.1 from this site, thanks.

    Ok, I wrote a clean 3.1 to the SD card, expanded the filesystem and copied

    SCPH1001.BIN to the folder /home/pi/RetroPie/BIOS

    The filesize of the file I used is 524,288 bytes and has an MD5 of
    924e392ed05558ffdb115408c263dccf

    that worked fine with the PSX games I tried, it worked fine upper or lower case.
    It couldnt find the bios file if I renamed it to a random filename.

    What is the MD5 of your BIOS? Does it match any here?

    Hi, mine looks fine, see image, I’m on 3.1 too.

    If you can confirm the user Pi has permission to read the bios file I would think it may be a customisation you have made to a config file.
    On my test I made no changes to them at all and it works fine.
    Are you able to reset them or try on a separate SD card to test?

    Hi Floob, I’m not sure how to check the permissions so will Google this and let you know.

    I’ve ordered a new SD card and will put the latest version on it.

    Permissions look good on the file:

    \\RETROPIE\configs\psx\Retroarch.cfg

    Pi user has read/write access
    Pi group has read access

    Are you able to compare my retroarch file with yours?

    I mean what are the permissions on the bios file.

    What do you get if you use PuTTY and logon to the Pi, run this command
    ls -lah /home/pi/RetroPie/BIOS/{BIOS filename}

    Your retroarch.cfg is wildly different to what you really need.
    Here are the originals, untouched which is what I’m using

    /opt/retropie/configs/all/retroarch.cfg
    http://pastebin.com/raw.php?i=15Nan1C1

    /opt/retropie/configs/psx/retroarch.cfg
    http://pastebin.com/raw.php?i=bUYH1A5b

    If you really want to edit your system specific retroarch.cfg with custom settings for RetroArch, check this video out

    Thanks Floob, I will test this tonight. Thanks for your time on this, most appreciated.

    First part:

    pi@retropie ~ $ ls -lah /home/pi/RetroPie/BIOS/scph1001.bin
    -rw-r–r– 1 pi pi 512K Oct 28 13:53 /home/pi/RetroPie/BIOS/scph1001.bin

    Adding system_directory = /home/pi/RetroPie/BIOS to opt/retropie/configs/all/retroarch.cfg fixed it.

    If I edit /opt/retropie/configs/psx/retroarch.cfg it gets overwritting by the contents of /opt/retropie/configs/psx/retroarch.cfg – weird eh.

    I tested WipEout 3 and maybe it is the power of the Pi2 but, the sound stutters at times, plus the graphics are grainy, I wondered if there are any tweaks/Filters?

    Thanks

    there’s an option to increase the resolution – have a look in the retroarch menu under ‘core options’. i forget what it’s called. however, it’ll probably just exacerbate your sound stutters! PCSX has no texture filters, aside from all the usual retroarch entire screen shaders.

    Does the performance on your WipeOut match the video here?
    Although first I would sort out those retroarch.cfg files – I dont know what you mean when you say that file overwrites itself. I’d be tempted to start with a clean install – or at least just use the defaults I provided above.
