Yes, im seeing a "fresh-new" created .VM1 file (with no saves) and after the offset 0x1200 i have all filled with "FF". This means this frames has not been writed
When some data is writed to a byte in a frame... the resting bytes are writed as "00"

Edit:
---------------------------
And write process needs to write a complete frame... frames are 128 bytes long with his "erase state" filled with FF's like this:

FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

If you want to write a valid value of "FF" in the first byte... you need to change all the others to difference it

FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

This can be considered a "fully writed frame"

There are any other similar file like this we can catch? it s still a bit unclear the function of this, if it s just the first "step during the creation of the vm1 or something more in specific case like corrupted file (and so to generate a "draft "of VM1 to carry the data of the corrupted file)
It s not easy question sorry in advance.
The title of the file, i didn t really think about it, but this thing, i can try to get, my first guess is: _New_ + the original name in hexa or decimal value, but can be also time format in hexa.

[sandungas]

I dont understand the first question.. but the second you are talking about the file name used when exporting single saves to usb in .PSV format (from both ps1 & ps2 memcards)
This file names are composed by "Disc_ID" + "Save_ID" + .PSV
Is easy, but im not sure if is explained in the wiki, im going to write a couple of examples:

Single game save from "soul reaver" (24.708 bytes)
----------------------------------
BASLUS-007086B61696E2061.PSV
Disc_ID ----> BASLUS-00708
Save_ID ---> 6B61696E2061 ---> kain a

Single game save from "God Of War II" (530.056 bytes)
------------------------------------
BESCES-54206474F574949.PSV
Disc_ID ----> BESCES-54206
Save_ID ---> 474F574949 ---> GOWII

Write the Save_ID's in a hexeditor to "translate" them

[Ada Love Lace]

For .PSV it s explained, the 2 question was about the "news fresh"(when first ftp a .VM1 and after create from XMB an VM1 with same name)
file which start "_NEW_ +16 digits."
e.g.: _NEW_21 01 04 39 00353780.VM1 : it look like timeformat such as: Date+HH+MM+SS the last 8 digits i can t get yet (GMT time for the 8 first digits)
----
Sorry in advance for the trivial questions, and i m slow to understand or to learn this couple of day so don t paid attention
----
You might be right about alpha or at least semi. Try to figure out a little more before asking Shendo.

Hey i changed one thing on the PARAM.SFO file, and when i tried to copy it back on to my PS3 it said 'The data is corrupt.' does anyone know how to stop this from coming up so i can play the altered save?

Thanks, it'll be much appreciated

I already butchered this thread too much and it seems you have generic problem, PM me with more details (what have you change, which purpose) and if it s become technical or else, we ll post here otherwise i ll try to help from PM.

[default_droid]

it's quite refreshing to see such an active ongoing technical discussion, i especially like the frequent additions to the ps3devwiki site as progress is made. many thanks and mad props for the continued effort guys!!

I ll take your words for me either, thanks you.
But truly, most of the things added recently on SFO page was thanks to Sandungas.

=====SYSTEM CHAT VOICE DISABLE===========

Today is also the same case with unknown flag not so unknown anymore.
Flag n7 is system chat voice disable (why is a bit complex to describe here and will PM Sandungas for details)
But to resume, it s from previous Sandungas work.
but problem is how to test it (the pop up message ll not likely not appear).
There are also chats setting so i guess it s possible to chat over internet apart from game but never used this function, neither on game.
Also i don t have the microphone for it (i imagine contrary case can work, like with this flag i can not receive chat voice from other but the last time someone was using chat online on game i first though my tv was haunted)
But if someone play with chat voice and want to confirm this flag disable it, i can prepare the SFO (let s imagine it still active flag and not less or more recently implemented on FW).
Anyone s idea to test? (at least it s the right period)
------
Message pop up on XMB or anything else i imagined fews weeks ago to "prove" this flag easily is unlikely going to happen (probably i didn t sleep enough last time i imagined that) so i don t really know how to test and make sure of this flag.
------
And also if anyone have theory why or when Sony has implemented this flag?
----------
Found the reason, it might be used for playstation home because people were using the chat voice in annoying way during a short period , but ...later added implemented on FW (because the flag is not on the latest version of home?)
Deroad was speaking about it fews pages later (but at that time, i though about system chat voice enable, not disable) and it make sense (x category was added on FW long time before they were really used so it can be that either or they added this flag on the tool for future use?)
...from laboratory side (and Sandungas will confirm it or not) and with one example (especially if we found that flag within one update version of HOME) , may be no test is needed to confirm it (under other games who use chat)
------
final theory: fw function update to disable playstation home system voice chat after receiving lot of complains, keep this function for others case and implemented as flag for quick and per case (through update game)....so might not be used yet but can be tested.
--------
When i said it s a bit complex how to get this flag n7...it s more: complex for me to explain in simple word but not hard to do and Sandungas can explain better than me if it s appropriate ( not sure my PM was so well to understand) and it was possible because of one other page Sandungas explained really well (and flags are just flags but at my level it s really nice to catch)

I had this sensation too several times, im sure there are several mistakes in the thread and sometimes it seems we are talking about things that has no relationship :D
But in the end... this is a brainstorming thread, and all is fine with the forum rules (maybe we flooded a bit, but there was some reason to write this walls of texts)

And i would like to see more people here brainstorming, because there are several things i have no idea (like online, backward compatibility, some game formats, etc...)

----------------------------------
This "chat disable" flag is a good example of this
I never used chat online, neither i have an idea about when was implemented chronologically or wich games used it at he beggining

But in few words... i agree that probably was used by "home" (not now because i saw one of the latest patches and is not there)

But there are 2 types of chat (text or voice)... im not sure how the flag can affect them

Also there are 2 ways to activate a voice chat (from XMB in you friend list... or inside a game) <-- im right ?
I think actually the games that supports chat contains the chat client (or part of it) in his game files... but maybe this was different before

----------------------
One question for people used to chat online....
-When you are inside a game that supports chat... well... it depends of the game, i imagine you can enable, disable, configure some setting, etc... but:
-If you press "PS" button in the dualshock (to go to XMB In-game) then in your friends column you can open a private chat with a friend?

Because if you can do this i understand is a good feature, and probably people asked to sony to implement it
And maybe this is the reason of this flag to be there... it was something that some developers had the option to disable to avoid conflitcs or rare errors... but at this point there is no reason to disable because doesnt give problems ?
************* [ - Post Merged - ] *************
I been lurking google a bit, and it seems there are lot of talks about this "private chat" (activated from XMB in-game... is the only way to do it)
Also some people talks about "cross-game" chat (between 2 players playing different games)

Its not supported yet... but there is LOT of people asking for it in official and not official forums... mostly because is supported in xbox360 <--- and this is important for sony

I have no idea if this is related with the flag, but it can be a feature that is in the firmware time ago but is not working fine yet

the only type of chat that i use online is the cross-game chat (only text). you can talk with other friends (also if they play different games) and you can add people from the chat itself. to use it you need to press the PS button. you can have multiple chat at the same time. once you receive a message, it will be showed like a normal psn message. if too long it will be shown partially

voice cross-chat is not possible since the ps3 cannot handle it.
