News/release from 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: HelldashX prxs violate Sony Copyright, so they are deleted from my homebrew (that now uses old prxs by M33).
To make RSPsar Dumper compatible with 3.80 Eboot you have to use HelldashX's prxs (take libpsardumper.prx and pspdecrypt.prx from HelldashX's 3.80 Psar Dumper release and put them in RS Folder overwriting existing lib.prx and pspdecrypt.prx).
Note: If you use HX prxs, you have to be conscious that you're violating Sony Copytights!!!
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":
Process:
3.71 firmware dumping from the Official Updater Eboot
Technical data:
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)
Result:
-"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...
Conclusions:
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!
Features
v2.1
-Fixed all license violation of the release
-Added source code to respect GPL license
-Deleted HelldashX prxs that violated Sony Copyrights
v2.0
-Possibility to extract and decrypt files from the 3.80 Officiale Updater Eboot.
-Added an exe file to make easier installing the homebrew on PSP with CF 3.80M33
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 menů 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 menů 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.
