#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](https://github.com/Yoti/psv_idpsdump/releases/)
|
|
- 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*
