+==== Tile, Table, and Palette locations ====
+  * HUD/layer 3/FX1/Message Box Tiles: D3200 in GAMEBOY mode
+  * Message Box Tile Tables: bank 85 or 0x28000
+  * Palette: Supposedly, all but 1 palette come from the first 2 (CRE/HUD) palettes.  Palette 18 seems to be loaded during the message box appearance.
+    * Palette 08 - Pink Text, White Instruction Type ('select' etc. text)
+    * Palette 0C - Blue Text (Can be used for White Instruction Type)
+    * Palette 18 - Green Text, Red Arrow (Save dialog)
+    * Palette 1C - Orange Text
+==== Tile Table Byte Explanation ====
+Tile Tables consist of 2 bytes, like 4E 28. The first byte is the tile number used in the tileset
+that the table uses. Row 1 of the tile table goes from 00-0F, row 2 is from 10-1F, and row 3 is 20-2F,
+and so on. If you open an unheadered rom in a tile editor and scroll down to D3200 and change to
+view to gameboy mode, you can see how this is done a lot easier. In the example 4E 28, you see that
+tile 4E (to the right of the 'S' tile) is a blank tile.
+The second byte consists of 3 things all together as one: The Palette Number, the Tile Flip, and the
+Priority Bit. You get the value of this byte by adding the 3 parts together, like, for our example,
+E 28, you can only get the 28 by having a palette number of 08, a flip of 00, and a priority bit of
+: 08 + 00 + 20 = 28. It's actually a bit more complex than that, but this is the easy way, and the
+only way you really need to know.
+The Palette Number can only be: 00, 04, 08, 0C, 10, 14, 18, 1C
+The Tile Flip can only be:
+  * 00 - No flip
+  * 40 - Horizontal flip
+  * 80 - Vertical flip
+  * C0 - Horizontal and vertical flip
+The Priority Bit can only be: 00 or 20
+  * 00 - Places tiles behind layer 1, layer 2, and sprites.
+  * 20 - Places tiles in front of layer 1, layer 2, and sprites.
+==== Letter to HEX Conversion Table ====
+By request, I'm including conversion tables to make it easy to type the letters into a ROM with a hex
+editor by seeing what their hex values are. Included is the original table and one for my map patch.
+Also, there are two apostrophes, but they're different. Maybe one is a single qoute and the other is
+an apostrophe, or they could be left single qoute and right single quote and one is used as an
+apostrophe... it's up to you how you use it, as they aren't used in-game.
+The item description text is complex, and not listed here. Use a tile editor for that.

+==== Other useful info ====
+Each line of a message box extends the entire screen. (32 8x8 pixel tiles)
+The lines above and below each message box consists of a single table placed both at the top and
+bottom of each message box, and is 1 screen wide (32 tiles)x 1 tile tall. You can add/subtract black
+tiles to alter the width of the large and small message boxes, but you must also alter all the message
+boxes below that go with each size in order to make them appear correct. If you edit this blank space,
+keep in mind that you are changing it for BOTH the top and bottom of the message boxes.
+The message dialog boxes use the transparent tile at 0E for all the invisible space around the boxes,
+or the Clearing Tiles. The priority bit hides these tiles behind layers 1 and 2, as well as sprites,
+but can be seen if there is nothing on layer 2, or if part of layer 2 is transparent. By default, you
+won't actually see those tiles because they are already using a transparent color.
+The black part of the message boxes uses tile 4E by default, which is black in the right palettes.
+The rest of the tiles are the letters and words at the bottom of the layer 3 tileset, as well as the
+HUD selections.
+You can use any tile in the layer 3 tileset in your messages.
+Mini hint maps from item messages, anyone?
+==== Message box locations (in hex, clean headerless rom) ====
+^ 28000-2803F | Blank lines above and below large (wide) message boxes (like missiles, power bombs, super missiles, items) |
+^ 28040-2807F | Blank lines above and below small (narrow) message boxes (like energy tank, reserve tank, beams, save)     |
+^ 28080-2877E | ASM used to determine which message box top and bottom to load and which message to load.                  |
+^ 28426-28435 | in the ASM: Button Tiles.  These are the letter tiles used by the game depending on what you chose for SHOT and DASH in the button config. See below. |
+^ 2823F       | in the ASM: '0E 00'.  This is the tile used as the clearing tiles above and below message boxes, and during transition.  By default, this tile is the transparent tile in the layer 3 tileset and has a priority of 00. |
+Button tiles:
+  E0 28 - A
+  E1 3C - B
+  F7 2C - X
+  F8 38 - Y
+  D0 38 - SEL
+  EB 38 - L
+  F1 38 - R
+E 28 - (space, unused?)

+Special thanks to Jathys for help on the color/flip/priority byte, as well
+as pointing me towards the location of the message box data. ^_^
