News/release from Red Squirrel:


Hi guys, sorry for my bad English.
This is my new update to RS Psar Dumper.
The changelog is very simple: ADDED COMPATIBILITY FOR 3.90 EBOOT!

Note: I want to remember to make you that to RS Psar Dumper compatible with 3.80-3.90 eboots you needs pspdecrypt.prx taken from 3.80 Psar Dumper by HelldashX.
I could not add the PRX to my release because of Sony Copyright!
So you have to know that if you use Helldashx's prx you are violating Sony Copyright!

What's?
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 and 3.90 Eboot you have to use HelldashX's prxs (take pspdecrypt.prx from HelldashX's 3.80 Psar Dumper release and put them in RS Folder overwriting existing 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
v2.2
-Increased the available buffer to allow the CORRECT extraction of the 3.90 Firmware from Official Updater Eboot.
-Now the 3.90F Firmware can be extracted perfectly
-Only X and O functions will work without problems, the SQUARE function (extract and decrypt of ALL files) works fine but ends with and error when search for reboot.bin!

Works as advertised.
I was able to decrypt 3.90 with this.

so basically this cannot be legally used?

unless there's a way to get the copywrited file without downloading (i.e. extraction)...

No, I don't think there is.
Correct me if I am wrong.
But if you wanted to decrypt 3.80 there isn't anyway to do that either without using the "copyrighted" prx included with the 3.80 newpsardumper anyways.
The PsarDumper with KL4E/KL3E (http://pspupdates.qj.net/PSP-FW-3-80-PsarDumper-with-KL4E-KL3E-decompressor/pg/49/aid/110584) is required.
All you have to do is copy the "pspdecrypt.prx" from the KL4E/KL3E version of newpsardumper (http://pspupdates.qj.net/PSP-FW-3-80-PsarDumper-with-KL4E-KL3E-decompressor/pg/49/aid/110584) to the RS folder of the newly compiled RSPsar Dumper v2.2.

I would rather just have a new version of psardumper that supports 3.90.
I don't need all the pretty colors.
It just needs to be recompiled to support a larger buffer.

This is the only change in RSPsar Dumper v2.2
