Playstation Vita VPK Notes

How to install the UPDATES:

1. Install game vpk
2. Copy update zip contents to the game folder
3. Make a GameTitleIDfolder in ux0:Patch/ folder in vitashell (ex: ux0:Patch/PCSE00000)
4. Copy the update zip contents to the new folder you just created in ux0:Patch/
5. Start the game, now it should not say to update your game and should detect the latest version.

How to install the DLC:

Copy the ADDCONT_PLAIN folder into root of ux0 for each item you want! e.g ux0:/addcont_plain/PCSE00000/*


0XFFFFFF means low storage.

Playstation / PSOne Mods

I had a few Playstation/PSOne systems laying around that would benefit to having a good old stealth chip. I started looking into the current status of mod chips for the Playstation and it all seems pretty much open sourced not. All the HEX dumps of the major chips are available online and they can be used with a simple $2 PIC. This is just some information I found and will be using this as a spot for notes as I mod a couple Playstation systems.

Available code:

MultiMode (MM)
Anti-Piracy Mod
Old Crow
Many others/variations of the above.

What code for what system?

Fat SCPH-100x = Stealth 2.8a
Fat SCPH-500x-900x = MM3
Slim PSOne 10x = MM3 (PAL model SCPH-102 which should use ONEChip) , Mayumi v5.1

What PIC should I use?

There are actually a few that are proven to work well. I went with SMD ICs since they have a smaller footprint and I always bend or trim the legs on the through hole ones anyways.


I will most likely go with the 12F508 due to cost. I will use the PicKit2 to program the 12F508.


RGH Xbox 360 Dash update Notes

Here are some quick notes from my dashboard update on my RGH Xbox 360

I am upgrading to dashboard 17489 which is the latest as of today.

Software needed:

  • Simple 360 NAND Flasher
  • xeBuild GUI

Lets do it:

  • Fist put the Simple 360 NAND Flasher on a USB key and run it on your Xbox from XEXMenu.
  • Backup your existing NAND (It will make a file called flashdmp.bin).
  • Open the flashdmp.bin in xeBuild GUI.
  • Make sure to have your CPU Key handy.
  • Make sure the latest dashboard is selected (17489) as of today.
  • Create update NAND (updflash.bin).
  • Copy updflash.bin to USB in the Simple 360 NAND Flasher folder.
  • Use USB in Xbox and run Simple 360 NAND Flasher again.
  • This time it will ask if you want to update the NAND since it detected the updflash.bin file.
  • System will reboot on its own. Check and make sure the dashboard updated.
