You know how if you put your VITA in sleep mode, sometimes your save files disappear?

Pirated games?

 

Mai dumps?

Just use the nonpdrm dumps

 

Don't use vitamin/mai dumps. They patch the games in not so elegant ways to try to make them work. Nonpdrm runs unmodified games with fake licenses, aka doing it properly.

There is a workaround to fix this:
1: Change the Time Format to 12-Hour Clock
2: Backup and delete "ux0:\user\00\savedata_backup\list.dat" file
3: Create a folder named "list.dat"
Example
"ux0:\user\00\savedata_backup\list.dat\"

 

This is in the Hacking & Homebrew section.

Yeah. Assuming the process even removes your save, you can just copy your save folders to another location. Copied and pasted the following info from a piracy thread so I don't know if it's okay to give the link, but you can find the source by copying and pasting a line into Google within quotes.

Spoiler: How to find the right game ID

When you first open Vitashell, move over to and press ux0: . (Just about everybody should know this much already)

Move over to and press app/ .

Now you'll find the folders for all of your installed games. Move over to and click on one of them (I believe MLCL00001/ is Vitashell 0.8, so you can skip that entirely).

Now move over and click on sce_sys/

Now move over and click on icon0.png. This will show the icon for the game. If you didn't pick the right folder, repeat steps 3-4 until you do.

Spoiler: How to backup your saves

Now that you know what the game ID is for your particular game, go to ux0:user/00/savedata/(Game ID)/.

Copy the folder that corresponds to your Game ID and back it up in another folder. I recommend calling the folder "SaveBackup" and placing the folder on the root of the memory card.

Now if your Vita has save issues for whatever reason, you can simply put the backup folder back to where the actual save data is supposed to be.

 

well this happens to me when I play ffx, and only happens when I put the vita to sleep/standby for a long time, like a day or so, and when I get back to save the game, my save files disappear and I can't save the game, but the save files came back after I quit the game and relaunch it

 

you have to refresh livearea by pressing triangle while on the root folders in vita shell

 

I had the same prob while playing persona 4 (imagine me losing hours of the game ), it's a bug with Enso, I used the 12H clock trick to fix it, like HtheB said

 

its not an enso bug its a bug with vitamin and mai dumps and even with this "fix" it still happens here and there

 

I confirm it's a Enso bug, as persona 4 is my own copy from the psstore, not a dump done by vitamin nor mai dump

 

I can confirm it happened WAY before enso was even a thing and hasn't happened ever since I started using nonpdrm

 

i think i had this done a long time ago, and what the op stated has happened to one of the game i played too.

and i believe it is even a Npdrm backup.
ys celceta.
save disappeared.

 

it's not an enso bug.

that bug only happens in games dumped by mai/vitamin, and it has been happening a long time before enso was a thing. it was NOT a legit persona copy then if it has happened to you. ^.^

it is known what causes this bug and is proven that it can only happen on decrypted games (mai/vt dumps)

 

I didn't know that, I did use some games dumped with vitamin and mai, but I had the issue once I installed Enso a few days after its release, at first I had the issue with Exist Archive, and I thought it's an issue with the dump, then I had the issue with persona 4 then I checked a bit online, people confirmed you could resolve it with the 12H trick, which indeed worked for me.

I never tried a Npdrm backup myself, so I cannot be sure, but I did play ys celceta (an Undub version btw) and I'm at the end of the game, no issues with the save

mmm, you might be right to some extent. My copy of persona is from EU psstore I bought a while back, and I did a trick to add original Japanese voices, I don't remember the tool name because I did this at the very beginning of Henkaku ^^
I used this :
Put the data/movie folder inside ux0atch/[TITLEID]/data

First of all, you need to add the plugin to the config.txt then reboot for the plugin to load and AFTER THAT refresh the livearea with the plugin active.

Also it's worth mentioning that the config.txt will NOT be loaded from ur0 if a config in ux0 exists. (if you're using an sd2vita adapter you have to use ur0. if you're not using the adapter you can just use the config.txt in ux0:/tai/)

If it still doesn't work you might want to check if the game you want to install is in the right format for the method you're trying to use.
