Index "compression"

Carrying this over from comments in the article to here since it is turning into more of a talk than a quick comment. This is relating to the part about the first dword in the index header indicating which of the 8 fields are in the header vs individual entries.

I found this isn't true. I know for sure the last dword can not come from the header - when my code tried it, the game didn't recognize the index. For obvious reasons the same probably goes for the offset. And realistically both sizes as well. Only the first 4 (3?) fields could realistically come from the header. (Tiger)

Agreed that the only observed values are the first three (four in Spore) fields but the rule holds true that far... (PLJ)

I know it looks nice and clean to say it extends all the way, and I wanted to say that as soon as I realized it was just a bitfield as well. But I have observed reaction to at least the 8th bit (Should be compression following the the rule) and the game didn't try to load anything out of the file like that. (Tiger)
