20-2F Special Tiles

The following table notes what the 20-2F "special tiles" are for each floor of the maze. The specifics on how these are actually defined will be covered elsewhere.

How These Tiles Are Implemented (And How To Change Them)

The specific data for these tiles begins at 0x850B. Each floor takes up 64 (0040) bytes. Each individual code is four bytes. So 0x850B is B1 Code 20, 0x850F is B1 Code 21, 0x8513 B1 Code 22, and so on. 0x854B is the start of B2's data, 0x858B is B3's data, etc.

The data for Floor...	Begins at address...
B1	0x850B
B2	0x854B
B3	0x858B
B4	0x85CB
B5	0x860B
B6	0x864B

The first byte of each four-byte code governs what type of square it is, and thus what the remaining three bytes mean.

For some codes, it may look like there is redundant data--for code 0C for instance, both the second and fourth bytes are the Item ID being checked. This is not a typo; it is actually how it is stored in the ROM, though I don't yet know why without a deep dive into the code.

If the first byte is	The square is	The second byte is	The third byte is	The fourth byte is
00	Nothing!	Nothing!	Nothing!	Nothing!
01	Stairs	East coordinate of destination	North coordinate of destination	Down coordinate of destination
02	Teleporter	East coordinate of destination	North coordinate of destination	Down coordinate of destination
03	Chute!	East coordinate of destination	North coordinate of destination	Down coordinate of destination
04	Rock! (Party dies and is transported back to the castle)	Nothing!	Nothing!	Nothing!
05	Pit	(Specifics unknown, but all three bytes seem to govern the power of the pit/how much damage you take)	-	-
06	OUCH	(Specifics unknown, but all three bytes seem to govern how much damage you take)	-	-
07	Spinner- faces you in a random direction when you step onto it	Nothing!	Nothing!	Nothing!
08	Message square	Nothing!	Pointer to the correct text	Usually Nothing (Will be 00), except for one on floor B4
09	The Mapiro Mohama Diromat square which teleports you to the castle	Nothing!	Pointer to the correct text	??? (Is FF, which may be what teleports you to castle)
0A	Teleporter with a message	???	Pointer to the correct text	??? (I think the two unknown bytes have to do with both how much to pay and where you teleport to afterward)
0B	Anti-magic square	Nothing!	Pointer to the correct text	Nothing!
0C	Square that checks for an item	Item ID checked for	Message to show if you don't have the item	Item ID checked for
0D	Message square with a "Will you search?" at the end	The item you'll acquire	Message to display	The item you'll acquire (One of these may be a check to see if you have the item before displaying anything)
0E	Message square with a "Will you trade?" at the end	The item you'll acquire	Message to display	The item you'll trade away
0F	A forced battle	The monster or monsters you'll fight	Nothing!	ID of an item--the game checks to see if you have it and bypasses the battle if you do. In-game, this is always the same ID as the item you get for winning the battle, hence my earlier confusion about what this byte actually was. What you get for winning the battle is determined elsewhere, probably with the enemy data.
10	Another forced battle that works differently from 0F, but I don't know exactly how yet.	The monster or monsters you'll fight	???	(This is the byte that perplexes me right now)
11	"One alone" (Teleport to Castle if more than one person in party)	Nothing!	Pointer to correct text?	Nothing!
12	Room on fire, kills if KOD Equipment not equipped	Nothing!	Pointer to correct text?	Nothing!
13	Exchange for Staff of Gnilda OR teleport	Nothing!	Pointer to correct text?	Nothing!
14	The Fountain Square	Nothing!	Pointer to the correct text?	???
16	A message square with a "Will you search?" that leads to a battle	The monster or monsters you'll fight	(??)	(??-maybe treasure you get for winning the fight. More research is needed)
