0syscall6 is tool that patches Playstation Vita's lv0's secure_kernel's syscall 6 (SELF/RVK checks).

It allows PS Vita to run new games or apps that requires a higher Firmware (3.60+). Useful for devs and users that don't want to update their Firmwares to play the latest games.

This will replace reF00D plugin, which previously did the same thing and without the need of keys.bin.

Installation

Put the plugin somewhere, preferably in ur0:tai/.

Add a line to the currently active tai/config.txt (ux0 or, preferably, ur0) under *KERNEL

*KERNEL
ur0:tai/0syscall6.skprx

Reboot.

User guide

What does syscall 6 patch do

  • Removes firmware/sdk version checks from SELFs. You can i.e play higher Firmware games on lower Firmwares, assuming that keys didn't change.
  • Removes RVK-list checks from SELFs. You can i.e use the revoked PSM-dev app.
  • Some other basic SELFs checks are removed.

Notes

  • The checks are removed from SELFs that are passed via syscall 6 as well as SM SELFs.
  • If the SELF uses new key revisions please use the _renga version with a decrypted kprx_auth_sm (.bin) in ur0:tai/.
    • psp2renga framework is required.
  • If you are using the psp2renga framework, please use the _renga version to prevent framework overwrite.
  • If you are using a hybrid firmware (HFW), please use the _hfw version to prevent wakeup crashes.

Compatibility

Tested by the author on 3.60/3.65 with 3.69 games.
