{{#seo: |title=Vita Homebrew Apps (Plugins) - GameBrew |title_mode=append |image=0syscall6vita2.png |image_alt=0syscall6 }} 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 Vita|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. ==Changelog== '''v1.3''' *This is a minor, cosmetic update compared to v1.2. *[standalone] Added a proper sysevent handler for resume => taihen is no longer required. *Added a version for HFW users. '''v1.2''' *The update_service secure module is now cached. **That should fix most wakeup crashes related to FS errors. *Venezia SPRAM is now used for the payload. **That should fix the weird bootlogo artifacting. **That should fix adrenaline wakeup compatibility issues. *[NMPRunner] Various optimizations made to speed-up the code exec. *psp2renga users please download the _renga version. '''v1.1''' *psp2renga users please download the _renga version. ==Credits== * Team Molecule / xyz for the update_sm 0x50002 exploit and help over discord. * Team Molecule for HenKaku and TaiHen. * TheFlow for dejavu and sysevent RE. * CelesteBlue for help with the resume stuff in early versions. == External links == * Twitter - https://twitter.com/skgleba/status/1199792736523767808 * GitHub - https://github.com/SKGleba/0syscall6 * Reddit - https://www.reddit.com/r/vitahacks/comments/e2mq7j/release_0syscall6_a_tool_that_patches_playstation/
