#ChovyProject v2 Now with PS1 Support !

chovy-sign is an application to allow you to convert PSP and PS1 ISO's to be playable on unmodified PSVita*

Setups: You need an (offical) PSP or PS1 license;

i recommend getting; Petz Saddle Club, LocoRoco Midnight Carnival, or Ape Quest Starter Pack because atleast one of these are free in most regions;

---

-- If you don't have a modded PSVita:

you will need:

• Any PS1 or PSP game (or demo) from the PS Store. (Petz Saddle Club, LocoRoco Midnight Carnival, etc..)
• Ability to connect PSVita to PC Content Manager (USB or WiFi)

obtaining keys:

• Copy an offical PS1 or PSP game to your PC using Content Manager,

• open chovy-sign2

• select either PSP or PS1 and click the "Get Keys" button

• click "EBOOT.PBP method",

• select the offical PS1 or PSP game you copied;

• click on select "Content Manager" backup

• you should see the RIF and KEY fields populate,

chovy-sign2 will remember this information for later so you only have to do this part one time;

getting psp or ps1 games:

• select either a PS1 BIN/CUE image or a UMD ISO image.
• click "go"
• once it finishes, you should be able to find the game availible to be copied over from Content Manager.

note: there may be some issues if you try this while having DLC for the game installed .

---

-- If you have a modded PSVita:

note: *you can still use the unmodified vita method on a hacked vita; if you would like *

note2: *bubbles created using the hacked vita method will still work on any unmodified vita, * *using the same PSN Account; however it requires a hacked vita to obtain some of the files, * that are required for this method;

you will need:

• Your ConsoleID/IDPS, Yoti has a tool to dump this availible here
• Your Consoles activation data file (located at tm0:/npdrm/act.dat)
• Any offical PSP/PS1 License file for your account (located at ux0:/pspemu/PSP/LICENSE/*.rif, or ux0:/bgdl/t/XXXXXX/temp.dat for downloads) you can also use PocketStation license or a PSP DLC license

note: your IDPS is unique to your PSVita and is used to identify your console on the PSN, so do not share it with other people

obtaining keys:

• open chovy-sign2
• select either PSP or PS1 and click the "Get Keys" button
• select "IDPS+RIF+ACT Method",
• copy in your IDPS
• browse for your license rif file
• browse for our act.dat file
• click generate keys

chovy-sign2 will remember this information for later so you only have to do this part one time;

getting psp or ps1 games:

• select either a PS1 BIN/CUE image or a UMD ISO image.
• click "go"
• once it finishes, you should be able to find the game availible to be copied over from Content Manager.
• alternatively, you can disable the "Use CMA" option in settings, and then copy the resulting TITLEID folder to ux0:/pspemu/PSP/GAME, then delete ux0:/id.dat, and reboot to trigger an app database update.

so overall there are 3 methods to obtain keys,

note: keys.txt is basically pointless now, in the bast it wasn't known how to use psp eboot to create ps1 games
