PSP Tool for encoding save data from PPSSPP to read on PSP and decoding PSP save to read on PPSSPP. Alpha version. Was only tested on Project Dive Extend. Build ===== Require PSP Toolchain with PSP SDK make release This will build ppssppsavetool.prx and kernelcall.prx. clean : make allclean How to use ========== Require PSP Toolchain with PRX Link and usb link, pspsh to work. Seems there is limitation for directories listing when running directly the tool from the PSP. A) PREPARING DATA ================= 1) Play the game on PPSSPP until a game save is done. This will create the file "ENCRYPT_INFO.BIN" in the save directory. It contain the encoding key and sdk version of the game. This file is the same for all save of the game, so you can use it on different save folder without the need to make them all on PPSSPP. 2) Run usbhostfs_pc. Then mount .ppsspp/PSP/SAVEDATA directory : mount 1 <path to .ppsspp/PSP/SAVEDATA> If you enter "drives", you should see host1: mapped to the directory. 3) Run PRX Link on the psp, and pspsh on the PC. B) ENCODING A SAVE FROM PPSSPP TO PSP ===================================== 1) From pspsh, run ppssppsavetool.prx. 2) In the menu, select "Encrypt", "host1:/". This will list the directories in ppsspp save directory which can be encoded. For a directory to appear, it must contain the ENCRYPT_INFO.BIN file, and the files of a ppsspp save. 3) After selecting the directory to encode, it will be copied into the PSP/SAVEGAME directory and encoded. Now you can play the save on the PSP. C) DECODING A SAVE FROM PSP TO PPSSPP ===================================== 1) You should have a directory in the PPSSPP save directory with the same name that the PSP save you want to convert. And in it, the "ENCRYPT_INFO.BIN" file. Ex : You want to decrypt the save in ms0:/PSP/SAVEDATA/XXXXYYY/ You create .ppsspp/PSP/SAVEDATA/XXXXYYY/ if not existing, and put the "ENCRYPT_INFO.BIN" generated before in it. 2) From pspsh, run ppssppsavetool.prx. 3) In the menu, select "decrypt", "host1:/". You should see your directory in the list. 4) After selecting it, the game decode the save and save it into the PPSSPP save directory. You can now launch your game in PPSSPP and load the save.
