Halo 3 Screenshot Tool

[Rogue_Modder]

yes, but if the app doesn't work then this helps.

[Kasumi000]

could this app be modified to extract screenshots from other games? I know of a few games that allow you to take screenshots but they are only viewable on the 360 either dash or in that proprietary game...

I've been trying to ask for help making an app that owuld allow me to extract screens from games like Gears of War 2, and I would incorporate the ability to extract screens from this game, too. There are other games I'd like to be able to get, like Oblivion, that game saves a screenshot when you save your game. No one wants to help me though.

GoW 2 is the same way as h3...

[HaLo2FrEeEk]

It's slightly different, but only VERY slightly. Sometimes the offset for Halo 3 screenshots start at D000 and sometimes at E000, GoW2 ones always start at E000, AFAIK.

And it's not about just getting the screenshots, like I said in my thread, I could do that myself with a hex editor. I want to learn a little bit of programming. I downloaded and installed Visual Studio 2008 so I could start getting my hands wet with this sort of thing, but I'm stuck after opening the file, I don't know how to read it as hex.

just ask some people on this site. They will know easy.

In C#

Code: Select all

            OpenFileDialog ofd = new OpenFileDialog();
            if (ofd.ShowDialog() == DialogResult.OK)
            {
                //setup reader
                FileStream fs = new FileStream(FileName, FileMode.Open);
                BinaryReader br = new BinaryReader(fs);
                //example read
                br.BaseStream.Position = 100;
                byte[] example = br.ReadBytes(800);
            }

[Rogue_Modder]

in vb.net:

Code: Select all

     Dim ofd As New OpenFileDialog()
     If ofd.ShowDialog() = DialogResult.OK Then
         'setup reader
         Dim fs As New FileStream(FileName, FileMode.Open)
         Dim br As New BinaryReader(fs)
         'example read
         br.BaseStream.Position = 100
         Dim example As Byte() = br.ReadBytes(800)
     End If

Thank you, both of you, I'll start with that and mess around with it to see what I can get.

Ok, here's the code I have so far:

Code: Select all

Imports System.IO
Public Class Form1

    Private Sub OpenButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenButton.Click
        Dim filereader As Stream = File.Open("R:\Gears Screenshots\00000001\shot_0000000A000F000B002402560F36B537", FileMode.Open, FileAccess.Read)
        Dim results As New BinaryReader(filereader)
        results.BaseStream.Position = &HE000
        Dim example As Byte
        Do Until Len(results)
            example &= results.ReadByte
        Loop
    End Sub
End Class

The problem is that when I run it and press the open button a little alert shows up telling me "InvalidCastException was unhandled" at the do until len(results) line. What I want to do is read from offset E000 to the end of the file. I've tried EOF and it doesn't seem to work either. I'm stuck here.

And when I get this to work, how will I access the example variable in another sub to save the file? I have 2 buttons, one for opening and one for saving. How do I go and tell it to save example as a file?

Wow.
I had no idea this topic was called, "teach me how to program"

[HaLo2FrEeEk]

Well no one is responding in my topic asking for help, and I was just replying to people's help posted here.

Code: Select all

Imports System.IO
Public Class Form1

    Private Sub OpenButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenButton.Click
        Dim filereader As Stream = File.Open("R:\Gears Screenshots\00000001\shot_0000000A000F000B002402560F36B537", FileMode.Open, FileAccess.Read)
        Dim results As New BinaryReader(filereader)
        results.BaseStream.Position = &HE000
        Dim data As Byte() = results.ReadBytes(results.BaseStream.Length - results.BaseStream.Position)
    End Sub

End Class

Fixed. Now get back on topic.

Tried it on vista 64 and 32 bit. Didn't work. Tried it on XP 32 bit and it works.

[HaLo2FrEeEk]

Maybe I'll try it on my Fiancee's computer, mine has Vista Ultimate x64 and even when I have the HDD plugged in through USB (the MS harddrive transfer kit) it still gives me an error when I try to run it. I'll try it on hers though...
