Inside Halo Custom Tags, there's 4 bytes after the tag class string, and also after each reflexive count. These have something to do with loading the tag into memory, and the size of chunks within the tag. Somebody had explained to me how these were calculated but now I don't remember. Anyone able to shed some light on it? Can't make heads or tails of what the values are or how they're calculated.



What I'm referencing, to clarify.

And before you ask, no, it's not in python, it's C++.

Edit:


Talked with moses more. The values I was looking for were the Tag Checksum, which he linked me to a refinery module to calculate, and the pointer, which is empty padding space. I was under the impression it was a valid pointer of some type because Guerilla and Sapien use the space when loading the tag the same way the game engine does, and writes the pointer to the tag. This data is stripped and replaced with the proper magic-offset pointer when the map is compiled, but in the meantime is meaningless garbage that isn't needed to read the tag.

In further news;



Thanks to Moses this is quickly underway.
