Although we have a means of bypassing the revoke, we currently cannot bypass the phone-home.įirmware 3.00+ recommended. This is because PSM has to phone home every day. Network is required once each day you decide to run homebrew. ![]() Blame Sony for never porting PSM tools to other operating systems. This also means that the VitaTV is not supported. The exploit requires a PC to run, so this is unfortunately a requirement. USB connection is required each time you wish to launch a homebrew. Hopefully, most of these limitations can be bypassed in a later release, but at this point, the following side effects will apply ![]() The bad news is that launching homebrews is not as simple as copying some files over. So what’s the catch? The good news is you don’t have to buy any obscure or expensive game (everything is free!). It is running natively with direct access to the GPU API calls (not within the PSM sandbox). The spinning-cube demo was coded up by me, linked together by hand (as the open SDK is currently incomplete), and launched with UVLoader. The demonstration video above shows UVLoader running as a VitaDefiler script (which supplies information for ASLR bypass). These tools, along with the open SDK (currently in development) will allow for developers to write Vita homebrew. If Sony decides to kill the Dev Assistant (and they will), it will refuse to run even if you have it installed. Second, every day, PSM phones home to see if it is revoked. These keys usually expire every three months, and Sony can refuse to issue them later. First, app-keys which are issued by Sony to developers to sign PSM content are required for the exploit to run. PSM+ is what I call the method I found to bypass the two kill-switches Sony placed into PSM to prevent this very scenario. VitaDefiler also serves as the ASLR (address-space-layout-randomization, a technique used by Sony to discourage exploitation) bypass for UVLoader. Originally developed for finding exploits, this tool can also be used by homebrew developers to test and debug their apps. Main features includes live peek/poke of userspace memory, execution of arbitrary ARM code, and a scripting interface for quickly running tasks. VitaDefiler is a RPC (remote procedure call) system for Vita userland. It can run homebrews on Vitas up to firmware 3.51 (at time of writing) However, there is no barrier that cannot be bypassed! The latest version includes support for SCE ELF relocations, NID poison antidote, and more. ![]() Since then, Sony has taken the source code and made loading code much, much, harder. The original version was written three years ago for firmware version 1.80. UVLoader 1.0 allows executables to be loaded on the PS Vita. Rejuvenate is composed of three main tools which together provides a platform for developers to write Vita homebrew. Now that Sony is killing PSM anyways and there is significant progress on the SDK, it seems that the time is right for a release. Other than laziness, the two main reasons were: 1) I believed that PSM was a great platform for indie developers and feared that releasing this would ensure PSM a death like OtherOS, and 2) there was no SDK for Vita homebrew so releasing the exploit would not benefit any users at all since they have no use for it. Many people have asked me why I did not release my tools for public consumption. It’s been almost three years since I found the first native exploit for the PS Vita. Rejuvenate requires PlayStation Mobile Development Assistant to be installed on your Vita! Sony will remove this from PSN soon, so if you wish to ever run homebrew apps on your PS Vita, you must download this app now! These tools cannot enable pirated or backup games to run (I’m not just saying this… the exploits used does not have enough privilege to enable such tasks). These unofficial software can run on any PS Vita handheld device without approval by Sony. The tools that will be released through the next couple of weeks will allow developers (not in contract with Sony) to develop and test games, apps, and more on the PS Vita. (Sadly, they did not give me a spot at the Sony E3 conference, so I have to make do with this blog post.) I am excited to announce Rejuvenate, a native homebrew platform for PS Vita. ![]()
