This is a simple app that I spent the day writing. It is in its early stages, so it doesn't do very much.

What does it do?

It converts Halo 2 Vista map headers to Halo 2 Xbox map headers. This allows you to use simple, non-parsing apps like DotHalo, etc, to edit and view Halo 2 Vista maps.

It backs up your map header to a .bin file, and then restores it when you want to convert your map back to the vista format.

Apps that are known to work with converted maps:


Apps that DON'T work:

-Any app that tries to parse the metadata, which includes almost all apps using halomap.dll

Maps that work:

-Single player maps

Maps that don't work:

-Multiplayer maps

Maps that are untested:

-All other types of maps

Download link:


It is a command line tool (for now), and syntax goes as follows:

Header.exe <switch> <map filename>


To convert to the Xbox header format:

Header.exe /X 00a_introduction.map

To convert back to the Vista header format:

Header.exe /V 00a_introduction.map

Have fun!


Well, I got H2X's "ScriptTools" app working (sort of) by modifying the source code of halomap.dll.

Does anyone still have this tool? I would like to use dothalo to modify some weapons in H2V but gravemind doesn't have the proper options. Sadly the link is dead.

The length of your life depends on my aim.

Ask supersniper or twinreaper perhaps they might know

It all depends on "what kind" of modifying you are trying to do. If it is simply just some projectile or value changes, you can use Gravemind or Ambiguous to do it.

Anything to do with render_models, sounds or shaders....you cant do much except use items that are already present in the map. In order for that, the above app would have to parse the metadata of the tags and dependies and then also have to recalculate offsets and padding in the map files.

If you really want to do new weapons or vehicles, I suggest you do a map redux and add those new weapons to that.

I've seen a tutorial for xbox to make a proper dual wielding for any weapon, which would not break the hand position for weapons like the BR or the carbine but it requires moving bone reflex which doesn't seem to be in Gravemind. I've also tried to modify the behavior (speed, resistance) of the warthog but it gets buggy when the file is modified. I haven't tried Ambiguous. I will give it a go and see if I can do it with it.

Thanks a lot!
