Difference in Security Sectors (same regiocode)

[creatox]

Hello everyone,

A question about the security sectors.

I downloaded the SS for BattleField2 (PAL) and the ISO. After downloading i noticed the ISO was already patched for Xtreme. So I guess the SS in the ISO must be exatly the same as the downloaded SS.

I extracted the SS out of the ISO with the XBOX360 SS Merger 1.6 tool.

After comparing the downloaded SS with the extracted SS there where 4 differences, see image:

This same thing hapend with TopSpin2.

So my questing is... could this be possible and will the ISO work after burning (havend tried id because I'm out of DL DVD's), or are those iso's fake or something...

There's 2 reasons I know why you get differences in pal SS's. One is that there is more than one pal region. I think there's at least PAL UK, PAL EUR and PAL AUS.

The other reason is caused by timing differences between drives in getting the response while reading the SS. These you shouldn't have to worry about, but the region code differences you do.

If the game publisher has set the region code on a game, then for example an iso with a PAL UK SS will not work on a PAL AUS 360 and vice versa.

It's also possible that there could be differences in the game itself so I guess your best option is to suck it and see...

Thanx for your response Syd.

So If i understand it correctly, just burn the already patched PAL iso and try. This ISO should be patched with the right PAL SS.

But, my PAL XBOX360°, will it read every PAL game? So AUS PAL and UK PAL?

If yes, it's just the matter of the right SS for each dump

This thread is getting a little too close to that topic we do not discuss so let's just say your best option is always to backup your own game so you have the right SS and game for your region. Anything other than that there is a possibility that it won't work because of region locking - even between different PAL regions. If you have to try other combinations, at the very least always keep PAL with PAL.

actually, it's not different PAL regions, just that the actual game data differs between the versions.. i.e. CoD2 UK has the swastika symbols, CoD2 german does not.

The differences in the image are 100% related to timing. You're actually looking at some responses which include a timing value. Nothing to worry about, this is normal.
