Booting VSH in Jpcsp

What is PSARDUMP?
and how do I copy files from my PSP?

Download the official 6.60 PSP Firmware: http://wololo.net/downloads/index.php/download/947

Install psardumper on your Memory Stick with the 6.60 firmware renamed as "EBOOT.PBP" on the root of your Memory Stick. Run psardumper and decrypt all files. Copy back the required decrypted files from your Memory Stick to Jpcsp. Copy only those files described in the first post of this thread. Do not copy all decrypted files as many of them are not supported yet by Jpcsp.

I installed official 6.60 PSP firmware
And installed psardumper according to your instructions.
At startup psardumper i got such a mistake: "game cannot be started the data is corrupted"
I tried to find solutions to this problem on the Internet, but unfortunately nothing could be found
I would be very grateful for your any help
