Hints
Juste's drop kick
You must have the Lizard Tail and the Glyph Feather for this trick. Have Juste jump twice, then press [Down] + [Jump]. She will drop kick, giving damage to an enemy.
Maxim's spells
Once you can play as Maxim, you can do spells that Juste cannot. For example, face the right side of the screen and press [Left], [Down], [Right], [Down], [Left] + [B] to duplicate Maxim. The two copies will fly around the screen, attacking enemies.
The spell used to summon duplicates that attack enemies ([Left], [Down], [Right], [Down], [Left] + [B] ) will summon a healing when there are no enemies around. This will enable Maxim to travel further and leisurely get to a save point. Facing right does seem to ensure your success at healing.
To activate the spell that make duplicate Maxim to kill all enemies on screen, press [Away], [Down/Away], [Down], [Down/Towards], [Towards], [Down/Towards], [Down], [Down/Away], [Away] + [B].
To activate the healing spell, press [Up], [Down/Towards], [Towards] + [B].
Summoning Tome
Go to Castle B's Skeleton Cave. First, have the Griffin's Wing and go into the double exit save room near the entrance area with the big pillar. While in the save room, save the game then use the Griffin's Wing and go through the roof. You will get Wizard's Urn and Summoning Tome.
Easy experience
When you enter the Room Of Illusion early in the game, you will encounter small flying enemies directly at the entrance. They are worth about 4 experience points each and never stop appearing. You can use them to level up as much as desired. A good way to kill them is to hold [B] so that your chain will just sit therem killing all the enemies as they appear.
Other warp room
When you are in a warp room between Castle A and B, press [Down] + [A] to teleport to another warp room on the map. For example, if you are in a warp room in castle A and press [Down] + [A], you will warp to another warp room.
Boss Rush message
Enable the "Play as Classic Simon" code and complete Boss Rush under the hard difficulty setting. You will see your time as usual, but there is also an ending sequence afterwards. It shows the castle from a different position. After a few seconds the castle will fade and a message reading "Simon Belmont forever" will appear.
Rare Ghost
The Rare Ghost can only be seen in specific parts of the castle. The easiest is in the room below the Clock Tower B warp point. Keep entering and exiting the room until you see it. Note: It will appear twice every twenty times at the very least. Once it sees you, it will run.
Gradius reference
When you combine the Bolt Spellbook with the Bible secondary weapon, your character will have a double orb shield in front of him. This shield is one of the shields from Konami's classic Gradius series, with similar sound effects when it collides with enemies.
Glitch: Keep relics
Get all of the Dracula relics and go to Castle B. Equip both the JB and MK Bracelets. Go down into the room and you will start fighting Maxim after talking to him. Defeat Maxim and all the Dracula relics will start flying around and Dracula Wraith will appear. When the battle starts, enter the pause menu and go to "Relics". You will see that you still have all of the Dracula relics, even though they flew away and made Dracula.
