How does the save system work exactly in the Konami Castlevania Anniversary Collection? Since this collection contains games that didn't have a save system back in the day it's not really clear how the game can be saved.
Does it work in save-state kind of way that you can save at any point and reload from that point onwards any time during a stage? Or does it auto-save after completing a stage and let's you restart from that point onwards? Or something completely different?
