Save file location - multi disc game (FF8)

mitu

@simongeoghegan Did you try renaming the save file to be identical to the name of the ROM. -Is this a save state (*.state) or memory save (.srm) ?

simongeoghegan

Hi @mitu - i'm not sure to be honest. Is there a way for me to find out whether its a state or memory save?

mitu

@simongeoghegan How did you create the save ?

simongeoghegan

Well a long time has passed since I've been on my retropie for one reason or another - unfortunately I still have this issue and following the recent FF8 remastering announcement, its got me wanting to play it again.

The below is the current BIN & CUE files I have within my psx folder for my Raspberry Pi:

I'm not sure where my saved files would be - i'm assuming on the memory card within the Raspberry Pi itself?

I've had a look for some walkthrough guides to see if this sort of topic is covered but couldn't see anything that might help.

Regards,
Simon

The save files should be alongside the ROM files, but I don't see one in the listing your posted. Did you re-configure the save files location ?

That is a backup folder no? The save file should be on the RetroPie memory card as you suggest they will be sidebyside with the .CUE file and use the same filename.
So when you start Disc 2 it will load "Final Fantasy VIII (USA) (Disc 2).srm" when you need to load the ~(Disc 1).srm

Savestates for multidisc games, if the wrong disc is inserted when loading the savestate will usually 10 of 10 freeze the psx.

And for the solution. Creating symlinks to the first (primary) memory card. This can be done on the consoles terminal. If SSH is enabled, you could access it using SSH on windows 10 open up the command prompt and use ssh like one of these examples should work. Replace retropie and the IP address with the pi's IP address or hostname

ssh pi@retropie
ssh 169.254.xxx.xxx
ssh pi@169.254.xxx.xxx

accept the key and log in with user and password credentials. Hopefully you remember your password, the default pass is raspberry.

Once on the PI's commandline type in the commands after pi@retropie:
note that linux filesystems are case sensitive, using Tab-Completion is a great aid to make sure you have typed the filename correctly. It would be a good idea to have a backup, because rm will delete the .srm (Psx Memory Card) and I am only assuming the first disc is the one that we will keep.

pi@retropie:
cd RetroPie/roms/psx
#This will make a copy of the disc 1 srm
cp "Final Fantasy VIII (USA) (Disc 1).srm" "Final Fantasy VIII.srm.bak"

#This will delete the saves for the Disc2 Disc3 and Disc4 .srm, I assume that there isn't anything saved to them if you haven't been able to load disc2.
#Be careful not to remove the .CUE or .BIN or the (Disc 1).srm
rm "Final Fantasy VIII (USA) (Disc 2).srm" "Final Fantasy VIII (USA) (Disc 3).srm" "Final Fantasy VIII (USA) (Disc 4).srm"

#Removing the .srm is necessary to clear the namespace so that we can create the symlinks in their place, the three commands will make a links to the (Disc 1).srm
ln -s "Final Fantasy VIII (USA) (Disc 1).srm" "Final Fantasy VIII (USA) (Disc 2).srm"
ln -s "Final Fantasy VIII (USA) (Disc 1).srm" "Final Fantasy VIII (USA) (Disc 3).srm"
ln -s "Final Fantasy VIII (USA) (Disc 1).srm" "Final Fantasy VIII (USA) (Disc 4).srm"

I hope that provided enough information to understand, but feel free to ask any questions and remember to backup the .srm.

mitu

@Efriim It's all nice and good, but there's no .srm file in ~/RetroPie/roms/psx - as you can see from the screenshot.

Efriim

@mitu It is a backup folder on OPs windows drive.

simongeoghegan

Thanks for both your help on this.

I've been following @Efriim workaround however I've got this far... (Apologies, I tried to attach a photo from my phone but couldn't figure it out).

pi@retroepie:~/RetroPie/ROMs/psx $ cp "Final Fantasy VIII (USA) (Disc 1).srm" "Final Fantasy VIII.srm.bak"
pi@retroepie:~/RetroPie/ROMs/psx $ rm "Final Fantasy VIII (USA) (Disc 2).srm" "Final Fantasy VIII (USA) (Disc 3).srm" "Final Fantasy VIII (USA) (Disc 4).srm"
rm: cannot remove 'Final Fantasy VIII (USA) (Disc 3).srm' : No such file or directory
rm: cannot remove 'Final Fantasy VIII (USA) (Disc 4).srm' : No such file or directory
pi@retropie:~/RetroPie/roms/psx $

I decided not to carry on with the next step just incase (and wasn't sure if it would work anyway given I had the error about discs 3 and 4 not exist.

Efriim

@simongeoghegan
That is normal, it is only important that the file is not there so that we can create the symlink in its place.
No saveram was created for disc 3 and disc 4 because they weren't ever loaded in retroarch.

mitu

@simongeoghegan My advice would be to create a .m3u file for the multi-disk game - as detailed in the docs, then rename the .srm you have with the same name as the .m3u file.
This way

disc switching is just changing the disc index (no browsing needed).
save file is not disc dependant - it's the name of the .m3u, the same for all discs.

cyperghost

@mitu +1 for this generic solutiuon

The symlink as @Efriim mentioned will likely work, too but you are bound to a filesystem that works with it. With a external USB device in FAT32 format this method is a failure.

simongeoghegan

Thanks for the suggestion @mitu and @cyperghost

I've had a read of this in the docs but it didn't seem too clear to them - would I make the filename changes within the menu I've been following the other workaround? If so, could you advise what code I have to use to do that please?

I'm not the most advanced of users so this is all very new to me and cautious about not wanting to delete/change anything I shouldn't! 🙂

@simongeoghegan
This can be done using the network share on windows.
Save the file as "Final Fantasy VIII.m3u"
the m3u contents will look like

Final Fantasy VIII (USA) (Disc 1).BIN
Final Fantasy VIII (USA) (Disc 2).BIN
Final Fantasy VIII (USA) (Disc 3).BIN
Final Fantasy VIII (USA) (Disc 4).BIN

and it will read "Final Fantasy VIII.srm" for the slot 1 memory card. So rename the backup to this.

You could also make multiple m3u files with differing indices that will load the disc first in the index.

Final Fantasy VIII (USA) (Disc 2).BIN
Final Fantasy VIII (USA) (Disc 1).BIN
Final Fantasy VIII (USA) (Disc 3).BIN
Final Fantasy VIII (USA) (Disc 4).BIN

and save this file as "Final Fantasy VIII (USA) (Disc 2).m3u", this would also use the same symlinks if they were already made previously for the associated (Disc #).CUE.

In this situation I think you could delete the .CUE files since the disc is only a single .BIN

No, you can browse to the \\retropie\roms\psx share folder do the modifications there - rename the .cue files and add a FF8.m3u file containing the CD discs entries. Rename your .srm and .state files to FF8.srm and FF8.state.
Then your restart Emulationstation and a new FF8 entry will pop-up, which is the game. Scrape it so the name and info will change to the right name and that's it.

simongeoghegan

Thanks for this, I've renamed as follows - so I just need to put the memory stick back into my Raspberry Pi and restart Emulation Station? (assuming I've done the name right!)

Efriim

@simongeoghegan
I didn't realize you were using a USB drive. I don't know if it will work, but the symlinks won't be able to be created on the usb default filesystem.

I think you will need to copy the Final Fantasy VIII.srm to the USB, usually it will look in the content directory so the .srm is always loaded in path to the rom media. If this default is different for USB I don't know.

And there is an extra disc, you would know more about it than me but FF8 is only a 4 disc game.

simongeoghegan

I have the memory card that is within the Raspberry Pi itself however I cant find my USB card reader so figured (possibly wrongly!) that I could replicate the m3u scenario on the memory stick instead as I believe everything on the memory stick copies across to the Raspberry Pi upon start up?

Again, I could be wrong - this was just my somewhat limited knowledge of things :)

Efriim

@simongeoghegan Though I think the usbromservice could make use of a menu for options like that, it doesn't yet have this function as it will instead copy the RetroPie folders from the sdcard to the USBdrive.

Samba is enabled by default, it is probably what you used transfer roms in the first place. Samba is basically a windows network share, so you can access it from the local network. Similar to SSH, you need the hostname or ip address of the pi and with it simply open windows explorer and in the address bar type one of:

\\169.254.ip.address\
\\retropie\
\\hostname*\

mitu

@simongeoghegan Judging by your picture, I don't think it's right. You renamed some FF7 .cue files to .cdX and now there's a FF8.cue (?).
Again, you should be able to do this over the network, via file shares, there's no need to move the USB around.
