Le CFW TaiHEN de YiFan Lu disponible

Comme il s'agit d'un CFW basé sur HENkaku, vous pouvez vous doutez qu'il faut être sous un firmware 3.60 sur votre PS Vita. 

 

taiHEN is a CFW framework for PS Vita™. When loaded with a kernel exploit, it acts as a common substrate for patching the system. taiHEN provides three main facilities:

 

It disables code signature checks to allow unsigned executables.

It exposes kernel peek/poke syscalls to user applications and allows loading of kernel modules.

Most importantly, it provides an API for hooking and replacing functions based off of substitute.

The last point means that developers can add custom patches to kernel, system applications, and games alike.

 

Building

 

To build, you need the latest version of the toolchain with kernel support. Then just use CMake to build.

 

$ mkdir build && cd build

$ cmake ../

$ make

Installation

 

taiHEN requires a separate kernel exploit to run. Once the exploit loads taihen.skprx to the kernel, taiHEN will take care of the rest. Please refer to documentations for the exploit for more information.

 

Plugins

 

Plugins are loaded either into kernel after taiHEN is loaded or on demand when an application is launched. taiHEN reads the configuration file in ux0:tai/config.txt.

 

The configuration that determines the plugins to load and the load order can be found in ux0:tai/config.txt. The format is very simple and self explanatory.

 

# ignored line starting with #

# Kernel plugins are started with taiHEN and are in this section

*KERNEL

ux0:app/MLCL00001/henkaku.skprx

ux0:path/to/another.skprx

ux0:tai/plugin3.skprx

ux0:data/tai/plugin4.skprx

ux0:data/tai/plugin5.skprx

# titleid for SceSettings

*NPXS10015

ux0:app/MLCL00001/henkaku.suprx

ux0:data/tai/some_settings_plugin.suprx

# titleid for Package Installer

*NPXS10031

ux0:path/to/some_pkg_installer_plgin.suprx

# titleid for SceShell is special (does not follow the XXXXYYYYY format)

*main

ux0:app/MLCL00001/henkaku.skprx

ux0:data/tai/shell_plgin.skprx

The key things to note are

 

# begins a comment, * begins a section, and any other character begins a path.

KERNEL is a special section name denoting to load a kernel plugin when taiHEN is started up. All other section names are the title id of the application/game in which to load the plugin at startup. Note that SceShell has a special title id of main.

In each section, there is a list of plugin paths that will be loaded in order. Paths can be anywhere but it is recommended that plugins reside in ux0:tai or ux0:data/tai. It is valid to have one plugin in multiple sections but the developer must ensure that the plugin knows which application it is loaded in if it needs to do things differently.

API

 

taiHEN exports an API interface both to kernel and to user. This interface is found in the documentation pages. You can either download the release or build taiHEN yourself. After that, you can include taihen.h in your project and link with libtaihen_stub.a and use taihen.json with vita- toolchain.
