Let's write the response. Based on your query, it appears you are looking for information regarding the Downloadable Content (DLC) for Castlevania: Harmony of Despair on the PlayStation 3, specifically in the context of .pkg files (the format used for PS3 game data).
I initially thought about listing prices, but the stores are down. I should focus on the content and installation method relevant to PKG files. I must emphasize the version update patch (1.04) because without it, the later DLC chapters are broken (invisible enemies). This is a critical "guide" tip.
