Anyone knows how to edit randomly PSP savegames?

Post by Kyto » Wed Dec 10, 2014 7:50 pm

hello,

anyone knows how to edit randomly PSP savegames? For the game Socom Fireteam Bravo 2 I need help, because the savegame file is only for 1 PSP and is protected by any code. I think it will be a model or Mac address give somewhere. But I identify with it and have it not look so only by Hex Editor tries but do not know where I should look for.

I want to but I use my old savegame again for the PSP and not on the new PSP tells me the game is that the savegame file was created on a different model please create a new savegame. It annoys me very possibly looking to have someone how to do it. Search for a long time for a solution.

Try decrypting the savegame (using Savegame Deemer or SED), then look into it to see if you find something that links it to the first PSP and try to change that

Use Savegame Deemer

I found the way to do it (I guess, I tested it with an emulator on a PC and my Vita) I sent you a PM.
You need to have both savedatas (one from the old PSP and one from the new one) decrypted
Open both savedata files in a hex editor, copy the first 16 bytes* from the save of the second PSP and replace the first 16 bytes of the save from the first PSP with that.
Encrypt it, now the save should work on the second PSP only.
(Also there's a difference between the 2 saves in 2 bytes at offset 0xE620, not sure what that is but changing it wasn't necessary, but I would do it anyways)
-------------------------------------------------------
*EDIT: looking at it a little bit more, it's just 10 bytes
Image
the first 4 bytes seems to be random for me, the other 6 are the MAC Adress (this is a save made by PPSSPP, that's why it's 01 02 03 04 05 06)

I figured out how to edit the mac address, check out my tutorial video: https://youtu.be/Jop20OXdaEk

This will retain your progress, unlocks, and customization! You can now transfer any FTB2 save to any PSP system (Even PSVita running Adrenaline). You can copy your old save to a new psp or give your save to a friend! This involves editing the mac address within Socom FTB2's save data files.
