I've just finished stages 10-12 on Castlevania (VC version). I noticed a lot of bugs and glitches. For example I could get weapons (the whip and the other weapons) directly from enemies. I could get weapons (like the axe) from candles but only occasionally and some weapons that were supposed to be on certain candles (like the holy water in stage 10) would just not be there. I even got that III-stone thing from a candle (only onec though).
Is this something that would happen on the original cart or is it something that is happening to the VC version only? Or is there something wrong with my copy of the game (do I have to redownload it?)
