100.2% Map Completion!

First do the trick for 100.1% map completion. Continue on with the story except when you get the Undine soul do not go to the Top Floor area. Go back through the Inner Quarters and Dance Hall. Then go to the Floating Garden. Proceed to the room that connects with the Clock Tower. Go to the upper right corner of the room. Use the Curly soul and you will be transported outside of the castle again. This time stand on the left side of the 2nd spike from the right. Jump and if you did it right you will be transported to The Arena and then the Top Floor and your map will be 100.2% completed.

100.3% Map Explored!

Ok, first you need to do the 100.2% map glitch, have the Giant Bat and Curly souls, and have not gone to the Chaos Realm
Enter the long verticle room connected to the frist save room of the Chapel. Stand on the platform that is just above the door leading out (not the stone on, you have to be under the stone one). Face right and press R to use the Curly soul. When Soma turns a strange color pause the game and switch Curly soul with the Giant Bat soul. Unpause and hold right and change into the bat. You should end up in the ceiling of the Save Room. Fly just above the statue on the right side and change back into Soma. You should end up in the Underground Reservoir, in the middle of a wall. When you very close to the top of the room hold right and press R to change into the bat. Change back into Soma when you reach the gap in the ceiling of that room. If you did the whole thing right you will fly up through several rooms and end up in the Chaotic Realm. The room of the Chaotic Realm is a tower/observatory room with a space background, if your not halfway off the screen the glitch won't work and you have to try again. Eventually you will be able to move again and your map percentage will now be 100.3%!

Glowing Soma

This glitch will make Soma glow for as long as you want. It does nothing else (as far as I know, I could be wrong) but it does make him really easy to see. First of all, you need either the Manticore, Devil, or Curly spirits. Next, make your way to the corridor in the Dance Hall (the one that leads up to the top level of the Dance Hall). Drop down from said top level, make your way to the last door (in the background) without killing anything, face left, and press R to transform. Keep holding it until you're just over the hole in the floor, and when the game starts to change you back, let go of the R button and do a slide. Voila! The game thinks that you fell through while you were changing back, so it replaces Soma's regular image with the really bright one. He'll stay this way until you use Devil, Manticore, or Curly again.

Surpass 100% Map Completion

First beat the game with 100% map completed, and a Curly soul, and start a new game +. Make your way to the chapel and head up the stairs in the room with all of the ghosts. make your way to the top left cornor of the room and stand under the platform that the Axe Armor was on. Next face to the right and back dash until your against the wall. Then use the Curly soul and you will be warped outside of the castle. Drop down the left side until you land on a platform and jump off the screen to the left. You will be transported to the Study and your map will be 100.1% completed.
