Developer Hammer-83 announces the release of version 4.0.0 of its PS5 development tool, PS5 Jar Loader, which has new features such as the implementation of AGC-based kernel read and write primitives, the payload to activate the Debug Settings menu, and improvements and reworks on the SDK as evidenced by the changelog.
What’s new in version 4.0.0:– Implemented AGC-based kernel read/write primitives: This feature now allows write access to kernel data on firmware 6.00 and later. Many thanks to flat_z for this contribution.- Payload to activate the Debug Settings menu: A new feature made possible by CryoNumb.- SDK improvements and reworks: The SDK has been optimized for a better user experience.- Display version numbers: JAR Loader and payload versions are now displayed, based on the Maven project version.
Important Notes:New payloads are not compatible with previous versions of the JAR Loader, and vice versa. The full ISO includes a menu and all JARs from that version, while the lite ISO only contains the remote JAR Loader, requiring the payloads to be sent over the network.This release introduces several essential payloads for developers:- UMTX bug implementations: Adapted by flat_z, Cryptogenic and cheburek3000, these payloads allow to obtain read/write access to the kernel. UMTX1 is recommended for its stability.- Byepervisor: A Cryptogenic implementation for advanced features.- Kernel dumper: Allows you to dump the kernel once read/write access has been obtained.- Jailbreak: Releases the BD-J process with superuser privileges and escapes it from the /app0 jail.- FTP Server: Provides root access after jailbreak.- Klog Server: Less stable when a client is connected.- Debug Settings: Enables or disables debug settings.
To help developers get started with the new features, several examples are provided:- A tennis mini-game.- A tool to view system properties.- A dump of the current JVM classpath.- A list of all directories in the filesystem using native calls.
