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.
- | floor | - | - | - | - | - | |
---|---|---|---|---|---|---|---|
Address Value | B1 | B2 | B3 | B4 | B5 | B6 | |
20 | Stairs to Castle | Stairs to 5E5N1D | Stairs to 0E0N2D | Stairs to 12E12N3D | Stairs to 7E12N4D | Stairs to 8E4N5D | |

2E | Pit | Ebony Key Door | Master Key Door | Spinner Tile | OUCH (Take damage) | Spinner | |
2F | Stronger Pit | Mithril Key Door | Rock! | Rock! | Even Stronger Pit | Demon Lord, but more research is needed on what actually triggers the fight to appear. |
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 first byte 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 |
05 | Pit | (Specifics unknown, but all three bytes seem to govern the power of the pit/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 | 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! | The item you'll get for winning the fight |
10 | Another forced battle that works differently from 0F, but I don't know exactly how yet. | The monster or monsters you'll fight | Nothing! | (This is the byte that perplexes me right now) |
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) |
