SoD's OoT 1.0 (U) Notes

[SoulofDeity]

These are the notes I've been taking for OoT 1.0 (U), be it assembly hacking, rom poking, reverse engineering gameshark code, porting debug rom stuff, etc.

It still a work in progress, but I hope it helps some of you people out there who don't like working with the debug rom

[mzxrules]

This is some good stuff. Some things...

8011A5D0 ram is the start position of the save data (which is where all of the stuff in your variables section is located). I posted some notes on it on the wiki here. I also have a table somewhere on ZeldaSpeedRuns which documents the perm scene flags in relation to v1.0. Aside from the different internal character set between PAL and NTSC, the save data has the same structure between versions.
 
In the Code file there should be some code that sets the Water Temple's default water level to 3 when creating a new file. Specifically, it writes a half word (at least it's a half word in the Debug version) of 4000h to 8011A734. Can you find that?
 

 

   $0007F31E  2  intro cutscene exit number

Why do you call an entrance an exit?

I'll have a go at it    I call the entrance an exit because that's what it is; an entry in the exit table

[mzxrules]

but it's not a table of exits. An entry does not store enough information to define a unique exit point.

[SoulofDeity]

I don't work much with maps anyway, that's just what my understanding of it was

 

btw, found it.   0x800900BC  in ram is the halfword default waterlevel. I can try to find it in the rom too, but it might take a while

 

EDIT:

nope, evidently not. found it quick. 0x00B0601A

 

EDIT #2:

yep, I changed the value to 0x2000, started a new game, made a dart for the water temple. it started off with the water on the second floor instead of the third.

 

 

---------------------------------

 

EDIT #3:

just wanted everyone to know I updated the first post with these new values and the extra offsets mzxrules mentioned. plus, I did a little digging and found out I was using the wrong pointers for the intro scene changing stuff and fixed it. also added the value used to change whether you start as adult link or child link

[spinout]

This is wonderful information. Some of it isn't even available for MQ debug. If the authors are cool with it it should go up on the wiki.

thanks

I've been blowing my brains out the past 2 hours tho. I noticed the savestate doc. on the wiki said there was a field that stated whether or not the file was a 64DD save, so I tried locating where the value was at in ram. I was hoping to trace it back to the rom and make a patch that makes all files be created as 64DD saves, but I honestly just can't find it...

I mean, I've found 4 areas in memory that contain save data; the first 3 only being active at the file menu, and you can edit the player name and whatnot in one of them. I tried changing all of the 0x00 bytes within 0x30 bytes of it to 0x01 since the wiki said changing it to 1 flags it as a 64DD save, but I didn't see any visual change (am I wrong in believing a DISK tag should appear?)

The fourth pointer appears in game, changing 0x8011A602 to 0x01 makes a little '0' appear under the player health. I'm honestly not sure if it's the timer or that field for the 64DD that I've found. I'm leaning towards the timer, but there's no icon, just the number '0'...

 

 

EDIT:

- I moved the pointers for the actor/object/scene tables to be relative to the start of code.zasm since that's where they're at

 

--------------------

 

~~progress~~ I found a gameshark code to enable the 64dd file on the debug rom, so I decided to take a step back and try to reverse engine the gameshark code; and managed to succeed to getting a rom value    changing the 2 bytes at 0x00AE05CE will make all files be created as 64dd files.

back to trying to figure this out on 1.0 (U) again

---------------------

 

lulz,  I found it,  0x00ACCF9E  (0x00045F9E in code.zasm), however you can't use it. it's a broken function. changing the value to 0x0001 will crash the game

 

*hangon*

I think it might have been something else. the ram address is $8005703C, if you write $0001 there and create a new file, it's a 64dd. maybe the game was just crashing because I had other saves created?

 

 

EDIT #???

nahp, I was right. editing the value in the rom causes it to crash (at least for the OoT 1.0 (U) rom, haven't tested the MQ one yet). the ram offset only works halfway as well. the created files will have a grey disk tag, but will not be registered

 

EDIT 0.0000523434 sec. l8r:

nahp. you can't set the value in the rom period. always crashes the game on both 1.0 (U) and MQ debug. well, at least I found the rom offsets for it in 1.0 (U)...

[SoulofDeity]

Changes:

• [*]fixed the ram offset of code (was accidently off by 2 bytes)

 

[*]added a value that allows you to force link to be a certain age (thanks to Airkita for finding this in the debug rom )

 

[mzxrules]

At B65C64 I found a table that determines what cutscene to play when entering from a particular entrance. It appears to be in the format

 

EEEE XX FF BBBBBBBB

 

E - is a two byte entrance index value

X - is currently unknown but i theorize that it factors into whether a cutscene should play all the time, or only when a flag is not set.

F - affects what event flag to flip when using a specific entrance

B - is offset to find the cutscene. First two digits are the bank number (02 for scene), last three is offset from that bank.

great find!    I'll add it to the doc.

 

 

EDIT:

just found the player state flags, pretty neat stuff. lets you turn link into a phantom who can phase through walls and floors

Nice! I'm curious as to how you find some of these RAM addresses.

[SoulofDeity]

Nice! I'm curious as to how you find some of these RAM addresses.

well, a couple of days ago I was helping Airkita find the offset that sets the default c-down button as an adult in the debug rom, and accidently found a value that when changed to 0x000A made link walk through walls, climb onto objects instantly, and when holding z drop through floors and lock his states (eg. if he's walking, he'll stay walking in air, if he's swimming, he'll stay swimming). So, I ported it to the 1.0 rom.

 

I set a breakpoint on the value, turns out it was a beq instruction, and changing it to 0x000A made it skip over some player state checking on register v0, I traced it back to an address stored in s0, and observed the changes in the values in game.

after goofing around for a bit, I pretty much had them all listed out.

I found a function that's only called at the start of the game and wrote a hook for it. I'm planning to use it to write a modloader

.org 0x8000085CdmaTransfer:.org 0x03472000evInitModLoader_rom:.org 0x00000080evInitModLoader_size:.org 0x80000E6CinitModLoader_hook:   addiu sp, sp, 0xFFF0   sw ra, 0x0000 (sp)   sw a0, 0x0004 (sp)   sw a1, 0x0008 (sp)   sw a2, 0x000C (sp)   li a0, evInitModLoader_rom   li a1, evInitModLoader_ram   jal dmaTransfer   li a2, evInitModLoader_size   j evInitModLoader_ram   nop.org 0x80170000evInitModLoader_ram:; put your code here, you will need to adjust evInitModLoader_size   lw ra, 0x0000 (sp)   lw a0, 0x0004 (sp)   lw a1, 0x0008 (sp)   lw a2, 0x000C (sp)   addiu sp, sp, 0xFFF0   lui v0, 0x0000   addiu v0, v0, 0x7430   sw ra, 0x001C (sp)   lui t6, 0x0001   addiu t6, t6, 0xD390   lui a1, 0x8001   addiu a1, a1, 0xB140   subu a2, t6, v0   jal dmaTransfer   or a0, v0, r0   lui t8, 0x8001   lw t8, 0xB144 (t8)   lui t7, 0x0000   addiu t7, t7, 0x1060   beq t7, t8, l80000EBC   lui a0, 0x8000   addiu a0, a0, 0x65D4   jal 0x800AF734   addiu a1, r0, 0x0345l80000EBC:   lui a0, 0x8000   lui a1, 0x8000   addiu a1, a1, 0x7D58   addiu a0, a0, 0x7D40   jal 0x80004220   addiu a2, r0, 0x0020   j 0x80000ED4   nop

the hook part overwrites the code at 0x00001A6C in the rom. the stub should be put at 0x03472000 in the rom

I figured out a formula for how scene files are allocated into memory

 

They are placed at 80384980 - file_size, without extra padding of course.

have you tested to make sure that still works when there are persistent objects like epona or princess ruto? if so, and it still works, that's a pretty useful find

[SoulofDeity]

I found 2 pretty useful things just now

$801DAB72	1-byte, item currently held in hand$8038A3A4	function to make link pull out / put away item   a0	= $801C84A0   a1	= $801DAA30   a2	= item to pull out  (00 = no item)

here's some rips of the logo stuff I did in case people need it. (you probably will since Rice's plugin screws up the texture formatting a bit)

 

NOTE: the below is actually 9 textures arranged in a 3x3 grid of 64x64 i4 textures!!!

 

(and because some people prefer to use the debug rom)

 

 

some extra notes the debug rom:

EDIT:

almost forgot, here's a patch for the 1.0 rom that enables file select. i did it because I was tired of having to retype it in every time I made a new nemu cheat file

[SoulofDeity]

took me forever to find these...

$8000085C	dmaTransfer   a0 = ram address   a1 = rom address   a2 = size$80000B0C	getFile   a0 = pointer to instance of structure with format:      ${vv vv vv vv dd dd dd dd ss ss ss}         v = rom virtual address         d = destination in ram (must be allocated!!!)         s = size of file$80020F88	setActorSize   a0 = pointer to the actor's structure   a1 = floating point scale to set it to$800812F0	spawnObject   a0 = $801D9C44   a1 = object number$80025110	spawnActor   a0 = $801CA0C4   a1 = $801C84A0 (global context)   a2 = actor number   sp = floating point x, y, z position        half-float (s10.5) x, y, z rotation        actor variable$800CAA70	setBackgroundMusic   a0 = sequence number

I re-posted the dmaTransfer function again because I found out I had it wrong before.

EDIT:

I figured this wasn't really important enough to make a new post about, but for those having problems getting epona to load in your custom maps...

epona:   actor    = $0014   variable = $0100   group    = $001Aother ridable horse (may not work):   actor    = $0014   variable = $FFFF   group    = $001A

[SoulofDeity]

I was working on a mod involving epona and came across something that truly confused me.

 

looking at the hierarchy in a hex editor, I noticed that unlike all the other objects, the entries in epona's hierarchy are 16-bytes each like in link's. however, here's where it gets interesting...it's apparently neither the link, normal, or beta hierarchy format.

I haven't figured out everything yet, but what I do know is the following:

Hierarchy Header:   ${oo oo oo oo nn 00 00 00}      o = offset of limb indices      n = number of limbsLimb Indices (for each limb):   ${oo oo oo oo}      o = offset o limb dataLimb Data:   ${xx xx yy yy zz zz cc ss tt tt tt tt oo oo oo oo}      x, y, z = position of bone      c = child index      s = sibling index      t = limb type         $00000000 = no display list         $00000004 = extended entry         $00000005 = unknown (no offset)         $0000000B = normal entry      o = offsetIf the limb type is a normal entry, then the offset points at a display list that can be directly rendered.If the limb type is an extended entry, then things get confusing. the offset points at the last entry in a table, which points to the start of the table itself, and has the following format:      ${?? ?? ss ss tt tt tt tt oo oo oo oo}         s = size of table / 16         t = pointer to start of table         o = offset of display list for limbthe rest of the entries are 16-bytes each. no idea what the first 8 bytes are, but the second 8 seem to be pointers to what looks like animation data; which is weird considering one of the limbs points to this table :/there seems to be only 1 extended limb in the horses hierarchy tho, and display list offset pointed to by the struct the limb points at seems to be made up using vertices from segment 08; which is most likely why most of the horse fails to load

some more stuff I found while looking for pointers to the audiobank

$80000E6C	initialize the dmadata table$800C6B54	play sequence	a0 = $00000000	a1 = sequence number

the sequence numbers are the ones on the wiki

[SoulofDeity]

here's a small mod I wrote using the play sequence function I listed above.
