The packaging itself doesn't come with a set of instructions or a typical CD manual. Instead, all such information is on the CD itself and can be viewed using Adobe Photoshop. The manual is broken up into six parts: How To Play, Castlevania, Castlevania II: Simon's Quest, Castlevania III: Dracula's Curse, Contra and Super Contra. The pages are set up to mimic those of the actual games' manuals from back in the NES days, only with more image detail. I won't show the "How To Play" portion because it's just text, and I won't be covering the Contra series for obvious reasons.
