Tutorial

In this tutorial, we will learn how to manually edit door entries.

All of the door entries are in start.dol and start at offset 0x002FFF80 in the NTSC-U / US version, and offset 0x003050A0 in the PAL / European version.

Each door entry itself is 28 bytes long. The exact breakdown of the an entry's layout can be found here.

Breakdown

As an example, I'll use the entry starting at offset 0x2FFFB8 (Which corresponds to the Spade door connects section C of the basement hallway to the Secret Altar) in order to break down how it's laid out. Here's the first entry in full:

01 00 00 00 00 48 0E 00 00 00 08 FC FF FF FE 70 FF FF EA AC 00 C8 01 2C 00 00 47 49

And here's the breakdown of each section:

Field Name	Description	Value (Hex)	Value (Decimal)	Outcome
Orientation	1 = front-facing, 2 = side-facing. 0 marks the end of the door list.	01	1	Since the value is 1, the door is front-facing.
Type	0 = door, 1 = viewport, 2 = window.	00	0	Since the value is 0, it renders as a door.
Padding	Two bytes of padding.	This value is intentionally empty.		N / A
JMP Door Number	This is the door number referenced in iteminfotable, objinfo, keyinfo, etc.	00 48	72	N / A
Model ID	Door Models	0E	14	Since the value is 14, it uses the Spade door model.
Door Index	The number of the door in the door list. This is used primarily in the Door Loading List.	00	0	This door's index is 0, so it's the first door to be loaded.
X Position	Permanent X spawn coordinates for the door or viewport.	00 00 08 FC	2300	The X coordinate is 2300, so it'll be placed there. Pretty self-explanatory.
Y Position	Permanent Y spawn coordinates for the door or viewport. -400 = Basement, 150 = Floor 1, 700 = Floor 2, and 1250 = Floor 3.	FF FF FE 70	-400	Since the Y position equals -400, that means this door is in the basement.
Z Position	Permanent Z spawn coordinates for the door or viewport.	FF FF EA AC	-5460	It's the Z position!
Viewport X Size	X size for the viewport drawn by a door or a normal viewport. Forward facing doors need a size of 200. Sideways facing doors need no X size.	00 C8	200	The value is 200, which is correct for a forward-facing door.
Viewport Y Size	Y size for the viewport drawn by a door or a normal viewport. All doors use a size of 300.	01 2C	300	All doors use size 300, as stated above.
Viewport Z Size	Z size for the viewport drawn by a door or a normal viewport. Forward facing doors need no Z size. Sideways facing doors need a size of 200.	00 00	0	Since this is forward-facing door, the value is 0.
Next Room Index	For forward facing doors, next room index refers to the room to the south of the door. For sideways facing doors, next room index refers to the room to the west of the door. Refer to the Door Loading List for room index numbers.	47	71	Room 71 is section C of the basement hallway (going to Secret Altar).
Current Room Index		49	73	Room 73 is the Secret Altar.

Conclusion

Based off of that breakdown, simply modify whichever values you please in order to get the results you desire.

(NOTE: The door frames are not a part of the doors' model themselves, they're a part of the rooms model. Therefore, if you'd like to add a door frame, you will have to modify the room's model.)
