I upload some saves from PSP on JPCSP, and when I try to load the saves, it shows me data load failed, is ther a way to make it to work.

games that uses firmware 2.00+ have save files encrypted , so you have to decrypt them before use it on jpcsp

thanks, I didnt know.

Readme Explication

Quote:When saving from a game, the savedata is saved as usual.
In addition to this, there will be another set of savedata created inside
/PSP/SAVEPLAIN on your memstick.
The folders will be named much like what they are named in /PSP/SAVEDATA,
consisting mostly of the game ID.

In the folders carrying the unencrypted savedata you'll find three file:

- <gameid>.BIN
One file will have the same name as the folder (gameid) plus the .BIN suffix.
This file will be usefull for devs only in most cases, it contains a dump
of the params structure that has been passed from the game to the syscall
used for savedata access.
This also contains the unique gamekey!!! ;-D

- SDINFO.BIN
This contains the descriptive texts that are shown in the XMB and the
save/load dialogs and is usually stored inside the PARAMS.SFO on the
original savedata.

- SDDATA.BIN
THIS IS WHAT YOU ARE LOOKING FOR! :-)))
This file contains the actual savedata, in it's pure, unencrypted form!
Edit it to all your needs, on the next load THIS will be loaded instead
of the original (encrypted) savedata.
