Retro Pie 4.2 PSX "Bios not found"
-
@pjft
Im sorry I am new to all this can you explain what fstab is? and where I can find it. -
-
i'm guessing, but i don't think either are running roms from USB, but rather using it to transfer via https://github.com/retropie/retropie-setup/wiki/Transferring-Roms#usb-stick
i'm not sure if this works to transfer BIOS files.. someone else said as much in another thread (can anyone confirm). if it doesn't, you'll have to use SFTP or samba transfers via wireless or a network cable.
(or you could copy it from the stick via the linux commandline, but that requires a bit more explanation)

@pjft
upon looking I have received an almost exact replica of what appears in the fstab section of this page.

@Skull-Knight Can you confirm the exact line of your USB mount point?
Is it something like
UUID=<drive ID> /home/pi/RetroPie vfat nofail,user,uid=pi,gid=pi 0 2?
If so, it means you're mounting on the RetroPie folder - just like me, so I know the set up.
It means your BIOS folder is currently in the SD card, but you're mounting over it.
You could certainly create a new folder on your USB drive, but the standard BIOS folder will usually already have some required BIOS files there.
My recommendation, as awful as it may seem, is:
- Boot your Pi without your USB drive there
- Now, as you navigate to the BIOS folder you will see one there
- Plug in a second USB drive (not THAT one you're using) and copy the BIOS folder to it
- Now copy the BIOS folder from that USB drive to the one you're using
- Restart your Pi with the USB drive plugged in
If that's not the case at all (i.e. if you're just doing what @dankcushions is suggesting) then, sure, you may just create a BIOS folder there, but I'm struggling to figure out why the folder would not exist there in the first place.
-
The only reason I can think of as to why the bios folder is not there is because I had to move everything to a new SD card as I ran out of space on the old one and maybe as it was moving everything for some reason it skipped on the bios folder.
-
@Skull-Knight Yeah, that could have been it then. I'd hope (unconfirmed) that if you go to the RetroPie-Setup script and update/install all packages again, the folder will be created... maybe?
Try it with the PSX emulator, see if it creates it. But yes, you can create it yourself - and, as long as you don't run into problems with other emulators, I suppose you'll be fine-ish. But yeah, if any emulator doesn't behave as expected, I'd suggest it could be related to that.
-
Ok I just looked back in the file manager and have found that the BIOS folder has reappeared inside the folder is
/fba
/mame2003
/palettes
*NstDatabase.xml
fast.bin
skip.bin
system.binI have no idea how the folder came back or if it was there all along and I was dumb enough not to see it but it still does not explain why the psx bios wont work.
-
@Skull-Knight Well, it does, right?
I don't see any PSX Bios file in it :)
-
Ohhhhh that explains it how do I create a psx bios folder?
-
@Skull-Knight You'll need to get the proper PSX Bios file and copy it there.
Where or how to get it is outside the scope of this forum, but they should reasonably easy to find using most search engines.
Follow the guidelines from this thread, or the wiki, on what file names to look for.
That being said, some PSX games will not run anyway, regardless of the BIOS file, so bear that in mind. PCSX-Rearmed doesn't support every single game, so if the BIOS warning stops showing up but the game you're trying to run doesn't work, either try to get it from a few different sources to see if it's a dump thing, or if it's just a compatibility thing.
Best of luck.
-
What format do they have to be put into the BIOS folder as?
in a zip file,on their own,ETC -
@Skull-Knight On their own. As described in the wiki page.
It should be something like scph<something>.bin, I believe, but the wiki is pretty much accurate.
-
I have fixed the problem It turns out that upon plugging my usb back in that the BIOS were just not copying to the BIOS folder so in the file manager I copied them manually and that solved the problem.
Thank you for helping me
-
@pjft can you tell me some of the u.s. roms that dont work?
-
@edmaul69 hmm. I don't know any US specific ROMS that don't work - and sorry if I sounded more like an expert in the subject than I really wanted to.
I know that ISS2000 does not run on the emulator, and I believe that in the emulator's GitHub page there are a few bugs filed on some games, so that's kind of what I meant by "not all games work". I didn't mean to suggest that there were a lot of them, sorry:)
Any particular game you'd be looking for, though?
-
@pjft no i was just curious and wanted to test them. Yes, iss 2000 doesnt work. No matter what i tried. Im curious as to why some euro games dont work. But luckily i dont use pal roms so not an issue for me.
-
@edmaul69 yeah. The Japanese version of the game didn't work either.
There's not much on the "official" compatibility list:
https://wiki.libretro.com/index.php?title=PlayStation_Core_Compatibility#PCSX-ReARMed
There's a list of issues on the original emulator:
https://wiki.libretro.com/index.php?title=PlayStation_Core_Compatibility#PCSX-ReARMed
And some on the libretro repository, which is the one we use:
https://github.com/libretro/pcsx_rearmed/issues?q=is%3Aopen+is%3Aissue
Maybe you can get some pointers in those lists as to what to experiment?
Hope it helps!

@pjft Fu*k compatibility lists... I can't understand why anyone would try and maintain something like that. Try it, does it work?
