Hi ;)
We are always adding the materials in highest quality we can (we get from publishers).
If the materials are better quality we are not changing it for lower, believe me :) So if we have 320kbs MP3- we are adding them.
Unfortunately it's not that easy with older games. In most cases publishers do not have materials for the games and sometimes they even have to buy their own game for example.
About Shogo manual- as far as I remember the publisher send us other manual few months ago so now on our servers is proper one.
We had few games (3 maybe 4, I'm not sure) that had the same situation (we released game with the first manual we've get, and replace when we've got other one) but it was only if we couldn't do anything else. I can assure you that since many months we don't have any Replacementdocs manuals :)
And yes- we have to have permission for every single bonus we are giving.
Ufff, that was long post :)
