Ok, I´m sure some of you have already noticed the that you can modify some things in the PS3 gamesave but I´ve never actually seen it mentioned. Heres everything I´ve found out.

ICON0.PNG - size 320x176
you can replace it with any .png of the same size or smaller. If you put a smaller image the ps3 will expand the image. If you put an image that´s to big or if you delete the image, the PS3 will use a default icon.

ICON1.PAM - the little video that you see. Since we don´t have anyway to create a .PAM file theres not much you can do except delete it(if the save has one) or replace with one from another gamesave. you can also use the XMB Game icon.pam from a ripped game. Most of the gamesave icon1.pam don´t have the sound incorporated in them but some like LAIR do. If you have an Icon1.pam, you won´t see the Icon0.png

PIC1.PNG - size 1000x560 This is the background image you see to the right of the icon. You can add, delete or remove with any image. If you put a smaller size the PS3 will expand it. if you put a bigger size the PS3 will put it to the right size or cut it, don´t remember which for certain. if you delete it there won´t be any default image.

SND0.AT3 - Here you can play around a little bit more. You can delete,add, or replace with another gamesave sound. You can also use the SND0.AT3 from PSP games or make custom sounds with the right programs. I never did it myself but there was a few custom sounds for PSP homebrew. If the icon1.pam has sound incorporated in the video and you add the SND0.AT3, this will override and you will hear the SND0.AT3 and not the sound that´s in the icon1.pam. I was hoping for some kind of conflict but nothing, not even the 2 playing at once.

You can delete all the files from a gamesave folder except PARAM.SFO and PARAM.PFD for it to remain an official save and transfer to the PS3 HDD. If you try to hexedit these files the PS3 will give you a corrupt message when you try to transfer to the PS3. If you just want to play around, you can alter the text from the PARAM.SFO and visualize that text on the PS3 if the save remains on the usb or memory sticks.

You can also add files in a gamesave and sneak them over to the ps3. The maximum limit for a PS3 gamesave is aproximately 1GB. All filenames must be in Capital letters and can only have a maximum of 8 letters with 3 letters for the extension. If the files don´t fit those specifications the PS3 will just ignore them and copy over the other files. So you could have a file called PSX.ISO and transfer it to the HDD hidden inside the save.

Also the PS3 actually supports one more video format in the XMB. The .PAM format which is using AVC encoding. If you have a save with an icon1.pam video, copy it to a usb, then go to video in the XMB, select your USB, press the triangle to view all and go to the gamesave folder. you can then view the video. unfortunately the .AT3 format is not supported so if the icon1.pam has it incorporated you won´t be able to play it.
just one last thing before I bore everyone to death. Copy a game save you have on the PS3, change the PIC1.PNG. Now view it on your usb and then view the original save on your PS3. The PS3 gets confused there for a moment and will show you the last PIC1.PNG visualized for that save. If you move around the XMB a little bit and then go back it will show you the correct image.

Phew,long post. I know there´s alot of useless info but I like to be thorough when I test and this is everything I could find out.

this file does not appear to contain any checksums or digital signatures for data integrity,
so from what I can figure you modify your account_id with the savegames account_id, alter the format of the file save directory to the format used in your country and you should be good to go, also updating the savedata_directory to be consistant with the altered directory name......

Now onto the PARAM.PFD files internal format......this does appear to contain the digital signatures etc

What are you using to edit the param.sfo. When I use the pbp unpackers editor their are some encryption types it doesn't recognize so it won't save it all and I wanna use the lock function to lock my gamesave

Nothing at the moment just a hexedit and time, as I said I have only just started on this

I'm happy to find someone is also working on this. I have been at this for the past couple of days, comparing and editing the PARAM.SFO file. Looking at online saved games of other users. I have come to a conclusion that the Account ID is the name of your PS3/PSN ID. It is written as ASCII, then incripted in Binary, and then written in Hex. It is mentioned 2 times in the file, however there is another part of unique coding to the PSN that I have not been able to determine what it is, gibberish to me now, but I found it in all my game files, and it was different for each online game save.

I believe this data is in #5 PARAMS.

So far I have tried changing the Account_ID of someone elses saved game to mine, and copying my PARAMS data into the binary of the SFO file.

The PS3 reads it as if it was my file, but when I try to copy it, I get a corrupted data.

I believe I have managed to get ownership of the saved game, but there is another element that I am missing. If you guys want to assist me with this major find, then let's all work together to get this done.

A point of warning, I don't know what adversed effects will happen if one takes ownership of a saved game that is Platinum Trophy worthy.

anyone know how to play the .pam movies on a computer?
