Hidden options
Start a new game with the name AXELORD.
Get the Holy Glasses and defeat Richter. Maria will have also escaped and tell you she's continuing her search for what happened to Richter.
For the 3rd and 4th endings, do this first: Get the Holy Glasses and equip them, but DON'T kill Richter. Instead, attack the green orb above him until it shatters. From here you'll go to the inverted castle.
Defeat Dracula with anything below 200% and you'll see Maria and Richter waiting for you outside the castle. Maria will decide not to follow Alucard and will return with Richter.
Get AT LEAST 199.1% and defeat Dracula. The others will be waiting, but Maria will decide to follow Alucard and try to help him cope with what he is.
Alternatively, equip the Shield Rod and Alucard Shield (the normal one), and press the Left- and Right-hand buttons at the same time. This will activate a special mode in which your shield is granted the abilities of all shields at once. Your shield is now the strongest weapon in the game (for a random amount of limited time). Ram into the Guardians with the Alucard Shield equipped and cause massive, rapid fire damage.
Continually kill the phantom sword in the inverted chapel.
