    Quick question: If I already have the save files for my game backups, are they loaded from the memory stick, or do I have to do something else to load these files?


    • Veskgar says:

      You need to take your save files from your PSP’s memory stick, copy them to the PS Vita –> PSAVEDATA –> adab456adfadf folder on your computer. Then copy the saves over with CMA.

    Dissidia 012 has a plain white screen after I make my save file. After the moogle sets up the play plan and asks me what difficulty I want the game cuts to an all white screen and after about two minutes an error message pops up. Please help!

    to ahbba daba ***,

    right click on the iso game and press rename, then type all capital letters yah dumb shipt

  4. shagrath says:

    I am having trouble with the naming. Windows keeps on adding .iso at the end.
    ex: GAMENAME.ISO.iso or GAMENAME.iso

    Any fix?

    • shagrath says:

      Nevermind. I got it working now.
      Under the Advanced Settings section on the View tab in the Folder Options dialog box, disable the tick box called Hide extensions for known file types.

    IVE CHANGED THE .iso to .ISO capitalized 8 CHARACTERS..
    but the game doesnt start.. T_T help pls..

  7. GothicIII says:

    Make sure you guys use unpatched ISOs. With patched ones youll get weird problems like above, or the ISO won’t even try to start. However some games have strong copyprotections (Like FF Duodecim or DJMax), so the chance is high, that they wont work.
    And I wanted to mention that you cant transfer ISOs with a size about 1.4GB; CMA will copy it, but right after that it gets deleted. With the FTP-Server it will work anyway—

  8. skmjohn1 says:

    @nutsplater i renamed the iso file and installed it just fine. the problem is that after starting the game (which i wouldn’t be ableto do if i didn’t rename the iso ***) the game cuts to an all white screen.

  9. skmjohn1 says:

    oh *** nevermind i thought you saying to ahbba was just you saying random gibberish. I apologize for the misunderstanding.

    Triing to “instal” Corpse Party

    after i say Yes to “Do you wnat to mov ethis backup to ms0:/ISO/?”

    it says “Not enough memory space. You need 742 MB but available 733MB”
    any ideas? :O

    • Jesus says:

      you need double the space of the iso you want to install

    • Lymus says:

      problem solved, iso had prolly an error or something
      made another dump, works now.

    • Monkey13 says:

      I’m also having the same problem I’m trying to move the backup of Kingdom Hearts:BBS to “ms0:/ISO/” and it says I don’t have enough space the game is 1.5 GB I have 8.8 GB free it’s a 32GB card. Is there any fix for this?

  19. African Child says:

    quick question, why do you nid to install the iso and move it?

  20. REALSTAR says:

    I added grand theft auto liberty city stories the iso all capital and only 8 letters to my ps vita savedata where the uno savedata folder is and yet I dont see it when I go to uno. All I see is the uno game and when I click x on it or triangle it restarts and I get this error (C1-2858-3) and it exits the uno game. I saw a post saying that a fix is is delete the save game data then install it again. I went on my ps vita and deleted but I noticed content manager wouldnt open and if it did it would be extremely slow. So I decided to turn off my vita. Now when I turn it on it has a black screen with the *** circling in the middle of the screen like its loading something and the blue ps button flashing. I have tried turning it off but I guess I will have to wait till the battery waste. I am extremely.

  21. Dan says:

    Im trying to get my wwe svr 11 game to work and its not been patched and i have deleted dummy files with umdgen but it still doesnt load. is there anything else i can do or is this game not compatible with this cfw

    • Dan says:

      I found a solution. I changed the cpu speed to 222/111. From what I gathered is that some games only run on certain cpu values. Try changing cpu speeds for different isos as that may be the problem.

  22. Error52 says:

    How do I change a file extension from lower case to upper case? I can’t find the answer on google.

  23. lester2020 says:

    Hi there. I have a question about file types like .ISO and such. How can I see the .iso in my Win 7, I wanted to avoid the .ISO.iso part. Any ideas?


    Also which games are compatible to play?

  24. Pan says:

    when i was trying to extract BOOKR.ZIP after it complete it just disappear from the list :S and i have to copy the file over again and it pretty much same thing over and over. idk where it go after i extract it. sorry for my bad english :S

  25. GlueGun says:

    Finely! Got it, Ummmmmmm…….. One Q?, Can it load
    plugins?.. from seplugins…some ho wwwwwww?????

    …………sadface : < cant add folder.

  26. lester2020 says:

    Disregard the last post, and I have another question.

    Is there a chance that it might brick like the PSP? Or is this exploit safe for all units.

    Also are the JP, US, and EU folders on the exploit can be run on a specific game or just the unit?


  27. GlueGun says:

    psp is a UNIT, and from how far the psp is, (signed execute
    code’s to run with the psp. im guessing its a no.
    because 5.03 HEN form way back was used to run code in the RAM,
    and 3.00 days flashed the Firmwares because no body wanted
    to pay the rumor of the 20k psp sdk, so they took the risk,
    and most of these works are done doing the,
    and data.psp, (Signed) compiled using a Encrypter. and
    you ask, well it break?. and where talking digital hardware.
    you have to be stupid to play with the ps vita psp flash0:/.

  28. XDarkMario says:

    every time i try to install a homebrew it pops p saying would like to extract the zip? i click yes ant then the game does not install and the zip is gone

  29. Jake says:

    Thanks to all who helped in making this hack 😀
    I just have one question: When you are trying to put more games on the vita do you have to overwrite the other games because that makes it take even longer

  30. ghassan says:

    please I NEED VIDEO please

  31. d says:

    Say if we had like 20 isos and 5 emulators all running good on the tnb menu 1.0.1, and we wanted to add just one more game, we would add our new iso to the psavedata and cma all the 21 isos and 5 emulators over to the vita, but when we overwrite the uno save data, do we have to extract all the 21 isos again ..? Is there an easier way to get around that so we can just extract the new iso only while having all our other stuff ready to play?

    • d says:

      Sorry, I just realized the guy above me ask the same question.

    • Vita_User says:

      @ d

      If you had 20 isos and 5 emulators and you wanted to add another you wouldn’t need to add everything again. Once isos or homebrew have been extracted / installed on your Vita, they are copied / extracted to your Ps Vita memory stick until you manually remove them. If you wanted to add another you would only copy the new iso into your savedata exploit folder. The only way you would have to add them all again would be if you forgot to extract / install them within the Tnc or accidentally deleted them.

      Remember, once you have installed something in the ecfw, you don’t need to worry about it, it stays on the memory stick!

  32. FIXED says:

    IF MENU FAILED TO LOAD BECAUSE U TRIED TO DELETE OR EXTRACT A FILE, now the menu is sc*** with black screen!!!!!!!!!! If ati is an extract problem, copy over the same extract folder zip that sc***, now you will have two icons that are the same when the menu loads. Since you can not delete the file otherwise it will get stuck and screw the menu, just copy over the savedata again this time without the file you want to delete. If you have problem with extracting or moving files because of not enough memory, use “psp filer 6.6” emulator to unzip or move files.

  33. qwerty says:

    when ever i put the iso in the save data folder, the exploit wont work and I get an error. once I re exploit it, it works but I cant put the iso on. what is the problem?

  34. jdshnugles says:

    Thank you guys a lot, thank you all, I’m so glad I got it working, it was pretty simple when I got myself on the right track. 😀

  35. k3nn says:

    wow, in the 2 days since i got CEF, i’ve been hooked on Wagic. at 1st i was really f@cking up because it’s not noob friendly like the PC Magic: the gathering was. eventually, i’m winning now, because i’ve basically created a good deck 😀

  36. Paolo says:

    Hello i do all the instruction but the uno game is not appearing after i copy it….

    – I install CMA 5
    – Then i download the uno exploit for 2.02 & put the Wagic game & named it WAGIC.ZIP & put it in the uno

    BUT STILL the uno icon is not there? please help anybody

  37. DeNi says:

    can we transfer psp savedata to vita? (savedata not isos)

  38. Matthew Taylor says:


    Just put MSG Peace Walker on Vita. Accepted message to move file to ISO folder however says no room yet there is 16GB left on the card.

  39. Skeith says:

    Hey sorry to be a bother but, I can open the exploit and make it to the TN 1.0.1 menu and my only option is to re execute UNO none of my homebrews or ISOs will show up. The naming isn’t a problem I fully understand the naming process or maybe I don’t I place my ISOs inside of the UNO save exploit name ex. MHFU.ISO or AZBZN.ISO. with the only homebrew I have attempted was wifi transfer and I placed it in the UNO exploit ex. PSP/GAME/WIFITRANSFER/EBOOT.PBP and that also didn’t work. IDK if this matter but i have the Assassin’s Creed white PSvita please help me 🙂 thanks

    • Ty says:

      I’m having a similar issue. I have the naming down CRISIS.ISO, but when I copy it over it wont appear in the TN 1.0.1 menu, just my copy of UNO and FFT which I purchased and installed from the sony store. I’m using the white ACIII vita if that makes any difference? Thanks in advance for any help.

      • Ty says:

        Figured it out by trying a cso conversion. Just converted the file to a .CSO and it apeared next time I transferred it.

      • Chris says:

        do your isos show up as an icon or a corrupt (unrecognized) file might be windows double naming it i used my xp comp (have iso burner app so recognizes them) and it was GAME.ISO.iso so it didnt show up on my vita im encountering a prob with space have 18gb left but says not enough memory

  40. Pat says:

    Where do you actually download stuff? Isos, hombrews, etc…
