iwd2 chr+gam format clarification


Recommended Posts

There was an unknown area of 9*8 bytes in the chr and gam files between the quick innates and quickslots.

Those are reserved for bard song resrefs (quicksongs).

There are no quick shapes stored, this is why the shapechanges couldn't be assigned to a button.


As a side-note, the iwd2 game format is not documented on iesdp, do you need a format description or it is just a link error?

Description would be welcome (and "download GemRB or DLTCEP source code" doesn't count).

The iwd2 gam also has the mage familiar header, but it is emptied.

I already managed to fill it with some meaningful .cre resref and employed the find familiar opcode (which also exists in iwd2)


By the way: you can use ielister on ANY game file in ANY game. It represents my understanding of the IE files the best.
