.dat files

[benh]

hi all

Can you give me a link to a program that opens .dat files because i need to open 1 from a firmware dump for a hack but i dont know how to open them, i have tryed notepad etc.

any suggestions

[yaustar]

Depends on the format of the .dat file. Try a hex editor such as xvi32.

[benh]

nope a hex editor didnt work any other ideas

[yaustar]

It probably be a proprietary format so you have to make you own tool to 'read' it.

[benh]

how would i make my own tool

[yaustar]

By coding it.

[benh]

But i wouldnt know how to make a program to open a file that i dont know has what kind of coding is in it

[yaustar]

Then this question below is pretty much moot unless you use this as excuse to start learning.

In short you are hacking a file format so you can edit it from a more 'readable' front end. You need to understand the way that the data is laid out by experimenting before you can write a proper tool to edit the file.

can u help me?

[yaustar]

No, for two reasons:
1. I don't have time
2. It really doesn't sound like you know what you are doing and by the nature of your previous questions, it looks like I will end up developing the tool rather then you.

[benh]

oh ok i want to open the .ireg file more than the .dat file, but i mean there must be some way of opening them becasue sony have made them

[yaustar]

Of course there is, what it DOESN'T mean is that the general public has access to that method hence you are reverse enginnering the format.

[benh]

r u sure theres no program to do it, because it opens in the hex editor and some of it is text but only bits the rest are symbols or maily there are a load of Y s with 2 dots above them

[yaustar]

Well unless you have access to the tools and source that Sony use to create/edit/read that file, you are either going to have to code your own or wait for someone else to do it for you.

If you are prepared to start hacking the format yourself at risk of screwing your PSP over, change a couple of values in a hex editor, record what happens when you try and use it on the PSP and work a theory/reason on why it happens and test the theory.

ok thanks for your advice

By coding it.

:rolleyes:
