RS Psar Dumper by Red Squirrel
RS Psar Dumper is a "derivated" from classical Psar Dumper (last version of which was released by HelldashX).
Its functions are the same of classical Psar Dumper (so dump Firmware from an Official Udpater Eboot), but it's more! Infact 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!
Infact this Homebrew has a USBHostfs connection function with a PC, so the program can read eboot directly from Hard Disk (that is a good profit because new Sony Updater Eboots weigh also more than 20Mb!) and it can also dump the Firmware directly on PC, so Memory Stick is NEVER used during the process!
Attention: v3 does NOT violate any Sony Copyright!
Infact if you use it under a 3.80 (or more) Firmware, the program 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.
What is the effective profit?
1. Well, first of all homebrew does not require free space on Memory Stick (that can be full too!)
2. You spare time because you do not need to copy files betwenn PC and Memory Stick!
3. Extracting and Dumping process require a very smaller time!
An example? Look to this my little "experiment":
3.71 firmware dumping from the Official Updater Eboot
Eboot of 22,5Mb (biggest released from Sony!).
Memory Stick used: Sony Memory Stick Pro Duo 2GB (that released with PSP pack!).
Process used: the most "onerous", so PSAR loading with extraction e decrompression of the Firmware (SQUARE key in the homebrew)
-"Classical" process executed on Memory Stick: about 90 seconds of waiting...
-"New" process executed on PC Hard Disk through USBHOSTFS: about 25 seconds of waiting...
Using new USBHOSTFS function you can gain more than one minute!
And then I do not calculate great times necessary to copy eboot from PC to Memory Stick, times that with USBHOSTFS are void!
- Fixed a critical bug in the previous version of pspdecrypt.prx.
In previous version if you signcheck a encrypted file you obtained a corrupted prx.
