Halo 3 Multiplayer Beta Bitmap Injection

1 post in this topic

What you will need:

  • Assembly 1.0.4817.30869 (This is only if you need to swap bitmaps)
  • Adjutant (This version will allow you to open Halo 3 Multiplayer Beta .maps)
  • Hex Editor (Any Hex Editor should do)


1. Backup

Before you start you will want to make sure you backup your in case you make an error.


2. Open Adjutant 

You will want to open up two .maps, the first being a Halo 3 Multiplayer Beta .map and the second being a .map of your choice.


3. Finding a Bitmap to Replace

You will want to find a bitmap in your second .map of choice that will be able to replace the targeted bitmap in the Halo 3 Multiplayer Beta .map.


The two bitmaps must have the same the same Format and must have the same Width and Height.


4. Extracting Bitmaps

Once you have found the bitmap you would like to extract then you will go to the Raw Extractor section and click on the bitmap, you will then right-click it and click Export This Image.




Then you will save the image as .bin. You will want to do this for both of the bitmaps. Also to avoid confusion naming the image files as something you can remember would be a good idea.


5. Hex Editing the

You will want open up three things in your Hex Editor: The Halo 3 Multiplayer Beta and the two bitmap .bin files.


You will then want to copy some hex-values from the targeted bitmap .bin that you are going to replace.




After copying those values go to your and find them by the hex-values that you just copied.




Once you found where the bitmap begins you will go to the bitmap .bin that you are using to replace, select all of it's hex values and copy them.


Then you will want to go back to your and click on the beginning of where the bitmap begins and write over it with your copied hex-values.




Save the result and you are done.


Good job you have successfully injected a bitmap into the Halo 3 beta.
