Important update: it seems for the EU version, you need your console to be set to English language in order for the exploit to work. I’m sure Frostegater will look into this, but in the meantime, if you use the EU version, please switch your console language to English!
Happy new year again! We eventually got convinced to not wait any longer and release the files for Frostegater’s port of Total_Noob’s CEF for Vita Firmware 2.02.
As a reminder, this tool relies on an exploit in the PSP Game UNO. You must own a legit copy of the UNO game on your PS Vita Firmware 2.02 in order for this exploit to run. CEF will let you play PSP Homebrews and PSP backups on your Vita. It does not allow you to play pirated Vita games, or PS Vita native content. To summarize, CEF does what a CFW or a HEN would do on a PSP.
Installation / How to use
Installation and how to run are explained in the readme, but for the sake of it:
- Extract the zip, and copy the folder that matches your version of the game (EU, JP, or US) to your content Manager PSAVEDATA folder. For example: My Documents/CMA/PSAVEDATA/1234567890abcdef/NPEH00020DATA00
- It is recommended to install OpenCMA, although until Sony releases a new firmware, the regular CMA client is ok too
- Copy the UNO savedata to your PS Vita with the content Manager
- run UNO on your PS Vita, and press X (or O) to continue, this should load the exploit
What next?
Now you’ll want some homebrews, and an explanation on how to install them. You can find a good selection of PSP homebrews here, and we explain how to install them on CEF here.
For more, head over to our /talk forums, where I’m sure many of us will be sharing tips, tricks, and pre-packaged homebrews that will run out of the box for this exploit.
Download
Before (or after) you download and run this exploit, please consider making a donation to Frostegater below:
You can also donate to Total_Noob on this link.
If for some crazy reason you want to donate to me for the awesome job I did coordinating the ninja release, please donate to the Red Cross of your country, this will make me and you feel even better about this hack
The files can be downloaded here. If you are seeing an old version of the download page, try this link instead.
Please report success/failure in the comments below or in the forums. I’ve tested the files several times myself, but a mistake is always a possibility.

first i have got ps vita wifi only
i have got psn plus account in united kingdom
i have the language set to ENGLISH UNITED STATES
i cant download uno because it will cost 4 Euro
and i cant sign in with US Account Because in this case i will format the PSV and i have many games and save gamescan anyone help me with downloading UNO
-
this video may help you. Btw you’ll need an extra ps vita card, one for each account: http://www.gamegen.com.br/ps-vita/como-trocar-de-conta-da-psn-sem-formatar-o-playstation-vita/
-
Sorry but if you have psn+ you can cough up 4 bucks too?
Regarding your ‘many games and save games’, back them up using (Open)CMA? then you can format or whatever and put them back later (savegames and all)

well im from mexico, and i must set language in english for the cfw works..
-
ISO’s work fine for me, but when i put in CSO’s, it goes black and says C1-2858-3 error. Why is that? is there any fix o this problem? I already tried 5 CSO games. but to no luck. ISO’s working though. Please help. I did renamed it and followed instructions. Help please?! Any help would be appreciated! thanks in advance!
-
some of the CSO’s you have are corrupted files. That happened to me awhile ago but some CSO’s i have are working perfectly fine if the error occurs again and again after you load the UNO game, its either you format your memory card if it doesn’t work. that’s what i did. it took awhile but yeah i ignored those corrupted CSO’s as possible. you can ask other’s help in terms of deleting the corrupt file in another way.
-
-
success!!
didn’t have 2 reinstall anything
thank you everybody that maid this possible -
HELP C1-2858-3 ERROR please
-
try changing your system language to english…
-
had the same error after the ubi logo in splinter cell…
-
-
I think is more about memory space
-
-
with naruto unh3 NARUTO:ISO & EBOOT:PBP (ZIP) TN tell me not enough memory space, you need 700mb, but available 318mb… UNO is the only thing i installed… and it´s ok 4.31gb in TN interface? i have 8gb memory installed… sorry my english
-
There must be a game installed or something, i was hitting a limit of 820mb when trying to install a iso, then i deleted some old minis and the iso was able to install, playing it (gta:cw) now. (works great
)-
I was getting the same problem even though it said I had 13GB of free space while trying to copy over a cso that was 1GB in size. After deleting another game, it copied over fine. I’m not sure why, maybe it has to do with how many official Psp games you already have.
-
After installing 6 games, im pretty sure the below is what goes on, but yea, still, just assumptions, dont read it as facts;
It looks like TN CFW uses the same ‘partition’ used to install games on your PS Vita for extracting the ISO’s & ZIP’s, even though it doesn’t actually install it there.Eventually, since i kept hitting limits, i backed up & removed all my games, installed all my psp isos, and put back my vita games backup
Still, looks like theres some minor ‘issues’ to be worked out, because even without any games installed i got told there was only ~1700mb room, and that cant be right when theres a 16gb memcard.
Maybe there is some homebrew (or somebody can make one?) that will allow us to fiddle with the size of the ‘partition’ used?On the other hand, this may very well be all there is to get out of the PSP emu, a ‘full on’ crack that runs on the Vita instead of the emu should have alot more space to work with.

works great
happy new year everyone! and happy new exploit also
-
Awesome, just updated from 1.81 and works like a charm
-
is there any forum where i can read/learn how to install and play psone games using an emulator or psx?
-
Followed instructions step by step . Up and running in an LA Vita version (MX). Loaded Tombraider for a start. Thank you for your excellent work guys. Enjoy your drinks and snacks !!
-
Thanks a LOT!!!!!!!!
Follow the guides on the readme and here and worked like a Charm
now I can play Both portable Assassins Creed game on the same system
-
Where can I find information on moving my save games from psp to psvita (I’m not in the mood to start Monster Hunter Freedom and Assassins Creed Bloodlines from the beginning).
Also, how do I delete the iso/homebrew from the vita if I have no access to file system either in the vita and on the pc?
thanks (just need to know where to find the info, or the the info itself if it’s not anywhere else)
-
copying UNO save game and a normal save game uses the same steps..
-
Just add it the same way you do for the exploit game saves.
-
-
-
Is there a way or will it maybe be possible in the future to run the Snes9xTYLmecm emulator with this? This is the best SNES emulator for PSP. Full speed games with 0 frameskip and vsync on. If this can be made to work on the Vita, life will be complete again!
-
Dont see why it wouldnt work, but testing it now, just for you. gimme a few mins
-
Hmm your right, it doesnt show up, going by exactly as the guide says making the zip with the EBOOT.PBP (and other files + roms)
-
I’ve gotten it to show up. I get the animated intro screen and everything. Its when I try to load a ROM that it always freezes while trying to apply speedhacks. I’ve tried a few different things and can’t get it to load a ROM. Really frustrating! Seeing as this is one of the best emulators for the PSP, I hope a solution can be found.
-
SNES does not run at full speed with no frameskip on the Vita unfortunately. Vita is emulating PSP hardware only.
-
Hmm, for me it simply vanishes after install, oh and it doesnt even show up as ‘installable’ when i make the ZIP with the directory structure explained in the guide. It only shows up when i put the EBOOT.PBP directly in the zips ‘root’
I can live with it though, im already super happy i got all my psp gta’s and ac:bloodlines running. Maybe in the near future in some patch, a emu hack for a newer firmware, or a ‘full on’ vita crack.

-
-
Works great, thanks so much!

Donated a few beers to Frostegater for it, well deserved
-
For anyone having problem transferring their homebrews/ISOs (most of mine wouldn’t transfer with Open CMA for some reason), use Vita FTP, it worked perfectly for me so far.
-
how to play psx with this cef?
-
Hope someone answer that because i want to know to
-
-
Sorry for newb, but how do i install gpsp on this? This is my first experience with CFW.
-
HELP
im new to this, how can i install emulators?-
Check the section on installing homebrew and isos. You have to zip them.
-
-
ok having a bit of a issue, i have the iso’s working fine but how to i set up the folders before i zip the file for install.. i get it to show up in the tn screen but when i extract it the files just go away not to sure what im doing wrong here.. and i have followed the above to the tee multiple times.. the way i have it set up is PSP/GAME/HOMBREW/EBOOT THEN HAVE IT ZIPPED TO SNES.ZIP AND USE STORE SETTING THANKS FOR ANY HELP
-
try installing psp filer,
http://zload.net/v2/archives/file/?id=241741.
extract that file and use the INSTALL.ZIP.
the filer is in it. should be able to install for you-
Thanks for the idea, having the exact same issue getting Snes9xTYL to work, ill try this too (ina few hours)
-
-
-
awesome really awesome
-
So for PSP back ups you put it in the exploit UNO savefolder? Thanks in advance!
-
Yes!
-
-
also just to add i know that Snes9xTYLmecm will not work on the vita im using older ver. so if this dose not work can i get a link to a workins snes emu also doing the same thing with nesterj for nes
-
Snes9X Euphoria
-
-
Thank you very much wololo frostgater and the rest of the devs. Got CEF installed and working fine. Got my first homebrew installed also….Quake Arena! Although the 64 mb version just comes up with a black screen but the 32 mb version works but then starts to freeze. But this isn’t related to the CEF I don’t think. PSP Quake works fine. Thanks again keep up the great work
-
hey, first i wanna say thanks! quick question tho, when i extract a zip homebrew it kinda freezes at 100% then i get an error and it restart. but it works after this extract. jw if this is normal?
-
Does anybody know where to get playstation all stars battle royale iso if not then any iso?
-
You should be able to buy it from most game stores.
If you mean you want an illegal downloaded version of the game, then piss off pirating leech! Go get a job and buy it like the rest of us!
-
agree stiffeno.. to poster above.. you need to buy it on stores or in psn store. there is no such thing as ps vita iso pirated for this… sorry
-
Just wondering (since i downloaded pretty much all my PSP games already) is it possible to make a ISO from a UMD? because i couldn’t find Vice City Stories which i do have for the PSP, can i use my PSP (loaded with CFW 660-C) to make an iso for my Vita??
Thanks in advance, been wondering this for a while.
-
yes just turn on psp on cfw press select a menu will pop up go were it saids usb device it is set to memory stick by deaful just swich it to umd disc then connect ur psp to the computer and it will show the umd game in an iso file drag it to the pc…u know the rest
-
Sweeeet, thanks man
-
-
-
-
-
don’t know if already been asked, but, exists some risk if I use the wifi connection to play on multiplayer vita games or buy things on psn store?
thks
-
I just want to say thank you guys for using a game that I already had because Lord knows I do not have money to be spending on such things. Yatta!
-
does anyone here have problems with the psminis, putting them on the exploit? i tried putting pac-man: ce on the exploit but as soon as i started uno, i got a black screen and an error which i could not get back into uno without starting all over. i mean pac-man worked for mad blocker but not uno.
-
thank you wololo and froste about the exploit,it’s work fined with me,since my psvita’s memory stick size is a little poor so I want to ask you that “can I install the same UNO that I already owned to the other memory stick or have to buy a new one ?” I hope to get reply soon
-
Yes you can!

That is (one of the reasons) why making a backup is so vital.
-
-
Going to buy uno now just quick question I had to pawn my vita last month for christmass if I biy on the ps3 and dl there will I be able to transfer it to my vita and still use the exploit?
-
yes, but only with a proxy like Charles and while the game is available on the store. So once the game is updated you’ll have to wait until PSN requires 2.03+, and the game is returned to the store, before you can transfer it.
-
Any suggestions on what I can do?
-
Not to be rude, but dont pawn your Vita, your best bet is pick that up now, install Uno, and backup to a PC, so you can use OpenCMA to transfer the game to the Vita even if sony blocks it
If you really cant pick up your Vita now, what MLC describes is your best, and only option.
-
-
-
Yes, I bought the Mad Blocker on the PS3 and transferred it that way. The only problem with that though is that if the game is taken off the PSN Store you won’t be able to transfer it to the PS Vita. I ran into that problem and had to wait for the Game to return to the store so I could transfer it. If you decide to go that route, Don’t update that Ps Vita. Once it’s back on the store you can transfer it by doing the Firmware version trick to by pass the update notice. See: a few pages back on – did-you-miss-the-ninja-release-then-hurry-up-and-get-ecfw for details.
-
Alright read what you told me to and I got the jist of it thing is I’m om 2.00 will that be a problem
-
-
-
I’m going to need a 32 GB memory card after installing CEF lol. I have a 16 GB card but I foresee it getting filled fast
-
Hey guys. To the people who need help with not being able to see the Homebrews. If you are using WINRar then once you have created the zip file Name it something with 8 characters but do not put .ZIP. Once created the zip file . at the top right corner is an up arrow and click that and it will show that the file is secretly shown as (8 characters you put minus the Parentheses).zip so you just right click and click rename and delete .zip and put .ZIP. it worked for me and i love the homebrews so hope this helps have fun
-
i forgot to put that you have to open the .zip file that was created so you can see the up arrow once you open it then you can click it and rename it
-
Here’s the Fix to the EU version. Works fine in “spanish” language, not sure in others. All the credits to “The Z” the creator of the fix. http://www.mediafire.com/?icon9420lazurv9
Un saludo desde España.-
Just tested on Italian language and it works fine. Thanks
-
-
Thank You Wololo, Frostgator and whoever helped in developing this! Great release!
-
does this work on 1.81 with UNO? I don’t really need to use it yet, but I wasn’t planning on upgrading right now since I have the earlier exploits too.
-
Everything works perfect… SNES, GEN, NES, PSP ISO. Great work everyone involved. You guys are amazing at what you do.
-
Everything works perfect… SNES, GEN, NES, PSP ISO/CSO. Great work everyone involved. You guys are amazing at what you do. Thanks!!
-
CPS1 works
CPS2 Bugs on video
-
-
Is uno still on the US store ?
-
Pretty sure it is I just bought so I can only asume they havnt remobed it and patched it yet
-
-
i have been hearing people having issue with God of War Ghost of Sparda giving black screens… The issue is your iso have been patched for lower PSP firmwares, unpatch it or get an unpatched version and it will work.
-
Just installed this for my Vita, works great 100% so far
!Thanks to all who made this release possible ^_^!
-
I need help installing emulators, whenever it finishes extracting it doesnt do anything
-
Can anyone else confirm it is still on the US store? I will update if it is.
-
Yes, it works.
-
-
Now with this new UNO exploit I finally had a reason to update my Vita from 1.81 to 2.02
! Seemed like I was stuck on 1.81 with no PSN access for AGES lol!I like the new YouTube app update! I seen the news about it a while back but couldnt test it due to using the Urbanix and Mad Blocker exploits!
Knowing my luck Sony will release 2.03 soon and ill lose access to the psn all over again -_-!
-
DO NOT OPEN THE UNO PROGRAM ONCE YOU ARE IN THE EXPLOIT! THIS WILL FREEZE YOUR VITA AND YOU HAVE TO DRAIN THE BATTERY BEFORE YOU CAN USE IT AGAIN!!! Sorry for the caps, I just wanted everyone to be warned.
-
Im pretty sure you can hold the power button for 30sec straight and it will force close it, its what I did when my Vita froze once!
-
Im actually 100% sure since i did this once (run uno from the emu) after installing a homebrew that didn’t show up
-
-
-
I wonder how many people will post here saying that they ‘once again’ missed out on the exploit LOL! I dont know why they even bother coming here, if they missed the last 10 billion exploits, what makes them think they will catch the next ones >.<!
-
Noone can confirm if it is on the store or not anymore?
-
hi, ps vhbl uno exploit cma 5.0 crack working
