RS Psar Dumper is a derivated from the original Psar Dumper homebrew for PSP (last version of which was released by HelldashX).

Its functions are the same of classical Psar Dumper (so to dump Firmware from an Official Update Eboot), but with extra features: this version has a user interface full of colors, more interactive and especially it has the new important function to make a dump of Firmware directly on PC, without using Memory Stick.

In fact this Homebrew has a USBHostfs connection function with a PC, so the program can read an eboot directly from Hard Disk (that is a good profit because new Sony Update Eboots sizes exceed 20 MB) and it can also dump the Firmware directly on PC, so Memory Stick is never used during the process.

Note: Since v3 this program does not violate any Sony Copyright. If you use it under a 3.80 (or more) Firmware, the program will try to get native support for decompress KL3E (to decompress reboot.bin) and the oldest 2LRZ (to decompress <- 3.73 firmwares). KL4E in this case is decrypted using an import exported by UtilsForKernel function.

Features

  • Does not require free space on Memory Stick.
  • You spare time because you do not need to copy files between PC and Memory Stick.
  • Extracting and dumping process require a very smaller time.

User guide

Procedure without using USBHOSTFS:

  • Insert eboot.pbp to decompress in the root of Memory Stick.
  • Insert homebrew folder RSPsarDumper in the PSP directory: /PSP/GAME37x/.
  • Insert folder called RS in the root of MemroY Stick.
  • Make sure from Recovery mode that kernel is 3.XX.
  • Start the homebrew from PSP under the menù Game → Memory Stick.

Procedure using USBHOSTFS:

  • Insert eboot.pbp to decompress in the same folder where Usbhostfs.exe is.
  • Insert homebrew folder RSPsarDumper in the PSP directory /PSP/GAME37x/.
  • Insert folder called RS in the root of MemroY Stick.
  • Make sure from Recovery mode that kernel is 3.xx.
  • Start the homebrew from PSP under the menù Game -> Memory Stick.

In both the cases will be created a folder called DUMP in the same directory where the Eboot (to decompress) is. When process will end, in DUMP folder you will can find Firmware files extracted from the Offical Updater Eboot chosen.
