The two-volume manga of Curse of Darkness was translated and published by Tokyopop on 2008, and can be bought for less than 20$ each: Volume 1, Volume 2.
Then, about the other Curse of Darkness manga, that came as a Japanese pre-order bonus, I did a translation that can be found here.
It is very, very short, just a prelude. It lasts for only a few pages, the dialogue is written on a poetic style of sorts, and the art is fantastic, as expected of Kojima.
You can read it yourself here!
And, I should mention that this manga isn't meant to be "canon." The truly canonical one is this one and it reads much more like a complete story.
