    If anyone is on a MAC, you can use the above technique with right clicking & selecting “compress” on the folder. The only thing you need to do after that is make sure the zip/file you create is all in uppercase including the .ZIP part.

    One other thing to note is not all homebrews will work. I seem to have about 75% success rate. I thought at 1st it might have been because I was using a MAC (the MAC creates hidden .DS_Store files all over the place, so I thought this might effect the installer) & they still don’t work when I use my P.C to download the files & make the installer.

    Found a solution,remember Open CMA 5 Offline? so,copy and paste those files into C:programs and search for Sony folder,in there CMA paste those files there and open bat.bat.Remember to turn off internet first i forgot to mention before i start.

    my question is how does it work with emulators?
    Where do I have to save the ROM Files?

    Thank you,

      Emulators work the same way. To install ROMs you’d need to add them to the ROMs folder in the emulator and then zip it.

      I’ve found that naming the zip “INSTALL.ZIP” usually fails and causes the XMB to think it’s corrupted data. Try naming it AAA.ZIP or something short if it wont work.

    ok I am having problem with pspfiler. At first it was working fine after I installed it. Then after some time when I open it again an error occurred like the common error that always show c1-2858-3. TAKE NOTE: All were setup to English US and all ISO games are working fine including snes emulator but only the pspfiler is not working, after it loads this error appeared C1-2858-3. Is there anything I can do to fix it? THanks

    Homebrew still doesn’t show after installing and deleted .ZIP file, is it incompatible? I’m installing PSP Filer 6.6, Vita ftp, pymenu 0.4 but none of them are showing in the game menu.

    • shadow

      I also had some problems with vita ftp. Try to make the PSP folder to ZIP (structure: e.g. PSP/GAME/vitaFTP) and just put it in the savegame folder. Works for me.

    • devon

      Go to video and click memory card then just go back to game folder and it will appear. The view just needs to be refreshed hence the going to video and coming back.

      Make sure that the name of files(XX.ZIP,EBOOT and folders) is in all capitals and under 5 letters (PSPFI.ZIP) and also make sure that u have directory right PSP/GAME/FTP

    how to put psp save data in cfw?

    • akian_aray

      I just copied it via CMA with other files and then moved it with PSP Filer. Or you can run Vita FTP, might be easier.

    I must say thanks for the video even though i didnt need it i can imagine all the idiots that do thumbs up z!

  18. ninjakakashi

    This worked fine for me with pspfiler but when it came to gpsp kai I also had to have the install folder in my folder.

    Might just be a glitch but I tried without and with multiple times and that is what worked for me haha

    This shows how little is know on the psp emu’s changed to the original psp in a way I think…

  19. sandisk998

    I transfer the INSTALL.ZIP file but when I am on the PSP XMB and I hit /\ and then Install I get the error: “Install Failed”. (80010016)
    Any Solutions?

    • sandisk998

      Update: I got it to work. Originally I could not install multiple emulators because I was receiving the error. First, I installed PSPFiler individually and it worked. I then downloaded some new emulators and installed them one after the other but when it came to the GPSP I was still receiving an error. It seems that the problem was GPSP all along. When I tried to install multiple homebrews, since GPSP shows up on the XMB first for the install, and the install couldn’t go past the GPSP none of my other emulators were installed.
      I tried another GPSP emulator and I put very few ROMS in the ROM folder and it worked this time.

  20. ninjakakashi

    If you don’t get an answer I would say lots of trial and error and to install psp filer 1st because that can help install things that get copied over but not in the right place and if you just want to use install files it helps for that aswell…

  21. Frezzno

    This tutorial helped a lot. Thank you The Z. Looking forward to read installment 2 and three.

  22. tHeN00bGamer

    ahhm i have a question, where can i get that 101 in 1 save data thing thnx? <<< srry noob here and do i need to purchase a game on psn???

  23. shindux

    any of you guys having trouble getting iso/cso on? i tried and fail…

  24. Bobo

    you must put the iso or cso in the same directory of tn-v4. change the name of the file into big letters, at the max 8 letters. including the extension .iso into .ISO or rather .cso into .CSO.
    here an example: thegame.iso -> THEGAME.ISO

    upload it with OpenCMA, start TN-V4, look at your memorycard, install the game (or not) and have fun!

  25. Bret

    So if I create a zip for say the SNES emulator with roms and everything, install it on my Vita, but want to add more Roms to it, how would I do that without deleting the ROMS/Save Games I already have on my vita? Thanks for everything guys you ALL rock!!!

    • Juan

      Yes! I Got the same question. What about backwards? I mean, if i play some snes game at the psp ui, my advances are going to be lost everytime I perform a transfer from the pc to the vita using CMA? This will be a normal operation each time i want to upload new homebrews to my vita right? So how can i be sure my advances are kept?

  26. Bobo

    use an another savegame to load rom on your memcard, then use pspfiler and move the roms into the right directory, it might work.

  27. AA Gamer

    Battle of Z sucks ***. I know it’s a demo, but the gameplay that they plan to have it as and the fighting mechanics isn’t gonna cut it. DBZ Tag tag team is a lot better this.

  28. maturin

    yop all I received my vita today and after having updated I have transferred megamix that was on my ps3 since Saturday, and I could run without problem

  29. l.o

    how can i install cwcheat?

  30. Tribolin

    im having problems with gpsp, i´ve downloaded a bios, but afer i try to load a rom, tn-v crashes, what’s the problem?

  31. Mike

    I have music on my tnv4 for some reason, it won’t delete

  32. Draven

    I recommend that everyone use The Z’s tutorial to install only one homebrew. VitaFTP. Once you have that, it’s SIMPLE to connect to your Vita’s emulated PSP memory card, and to directly copy and paste ISOs, homebrews and plugins. Just as easy as copying and pasting to a regular PSP was. It takes a lot longer than it does for the PSP, but, it’s worth the lack of hassle and effort.

  33. Smoker1

    OK, I do not know what it is with this, either it is the Vita or OpenCMA, but this thing is VERY twitchy/picky. For some Files, be it CSOs, ISOs, or ZIPs, You have to use trial and error for transferring. For example:
    Take Family Guy PSP Game. I tried to have it as FAMGUY.CSO, FAMILYGY.CSO, and it will not transfer. However, I typed it as FAMGY.CSO and it worked no problem. I also tried to send over the N64 Emulator, and I dont remember how I finally did it, but after a few tried, doing different Names, I finally sent it to my Vita.
    Basically, I am guessing it is possible that Sony has made it so certain file names it recognizes will not work. So if at first you do not succeed, try a different name.
    Have tried running some Emus from Wololo Downloads Section like CPS2PSP, but it will not run. Will be trying other Releases to see if I can get one working.

    I did all of the z steps but iso coming out corrupted what do I do


    Its hit or miss. NesterJ installed without an issue, clicked install, deleted the file after install, returned to Vita homescreen, returned to XMB, was there, ran fine. Did same thing for other emulators, installed, deleted, returned and not there. Tried not deleting the file after install, it would still be there but requiring an install. Im starting to think some run fine with TN-V4, and some do not. Eventually if we get a list together, that’d be great.

    I can’t wait for Christmas morning to get my amazon gift card so I can order myself another vita 1st one broke after dropping off my back porch accidentally. Looking forward to the next kxploit release, hopefully after Christmas, so I can get involved and help out here, I’ve got plenty of psp experience and all of what I’ve been reading seems pretty similar. Wish I could help now but don’t want to give any bad info as there seem to be slight differences with the way things were done on psp. Thanks TN, Wololo, The Zett, Mathieulh, and all others that helped bring this to the people, you make the handheld we love even better.

  37. olivier
