V34 Libretro PPSSPP Save Issues

[MoneyMal]

Saving in Libretro PPSSPP is broken for me after upgrading to V34 Stable. When attempting to create a save file I’m met with an “Unable to save” message and results in a corrupted save file. Save files I had before the upgrade have disappeared. I'm aware that the game save location has changed in this release but has seemingly created a conflict in my system.

I'm having the exact same problem. Really hoping this gets fixed.

I have found a work around for creating new saves for the time being. Start your game with the stand alone PPSSPP emulator and create a save file. Then exit and switch to Libretro PPSSPP. The save file previously created with PPSSPP should work, at least it works for me. I think old save files created pre V34 will have to be moved to the new directory. I have not tested that though. Hope that helps.

Thanks very much. It worked, although, in a slightly different way. I found that any game I tried to save with the libretro core of PPSSPP previously, would not work at all in the standalone version (I'd get thrown back to the games list right after selecting the game). So, I tried deleting the save files/folders of those games to see if that would do anything. Luckily, doing that seemed to work and the standalone PPSSPP started the games just fine. I then saved, switched back to the libretro core and noted that the saves I made in the standalone version didn't show up. However, I was indeed able to then save using the libretro core after that. Thanks again.

I don't have any v34 install any more, but I think it's fixed in the current dev build for Batocera 35 thanks to #6374

Thanks for the info. I updated to the most current dev build but unfortunately my issue still persists.

that was for standalone ppsspp - need to look into libretro-ppsspp

I'm having this issue as well.

PSP emulation seemed to work fine for me when using v33. Could save without any issues.
Upgraded to v34 and libretro:PPSSPP doesn't seem to want to save
For standard PSSPP, I can't launch games, it immediately crashes back to EmulationStation.

libretro:PPSSPP is odd though. I think what is happening is the following
If I delete the SAVES dir, it is able to make a new folder for the ROM and save a file. But after saving it complains that the file is corrupted.
If the SAVES dir exists, it can't save at all.
Haven't exhaustively tested it, but I think that description is consistent with what I'm seeing.

@LukeMW I tried deleting the PSP Saves folder (\SAVES\psp\SAVEDATA), but I still can't launch standard PPSSPP. Did you delete any other folders or take any other steps to work around the issue?

Also, FWIW, I'm using a network share for my SAVES and ROMS dir, not sure if relevant

[LukeMW]

@SirRamEsq Well, I didn't delete the actual PSP saves folder, I deleted the individual game saves within that folder.

@LukeMW Thanks for the clarification. Unfortunately, standard PPSSPP still doesn't boot for me :(

If it helps, The following is the error log for standard PPSSPP

No idea why all the graphics backends are failing ¯\(ツ)/¯
