should we delete this file, then?

not sure. I suppose that if there are no go package in main dir, this file isn't necessary.
It could be inside of pkg dir

I think these termination bytes are also artifacts of the encoding, and likely not needed in the decoded struct.

the problem is, that this value isn't the same in certain dc6 files.
from documentation, we can see, that:
UBYTE termination[4]; // EE EE EE EE or CD CD CD CD and it may be of importance for d2 game

I'm not sure about this.
Why would you need to pass the palette in?
Why is the palette a data member of each frame?
The DC6 should only have a single palette, and the frames should not need a palette to be loaded...

please note that it is a pointer to the palette used by dc6, not palette itself.
Maybe the better solution is to add (*Frame).Palette method to set it?

This is an artifact of the encoding, we don't need to store the termination bytes.
replace pdc6lib -> dc6lib
- replace github.com/gravestanch/bitstream with OpenDiablo2 upstream - fix broken tests

@gravestench thanks for your reviews! just fixed most of them |
Hi,
