Nailed it.

CODE
void *GetOSTAtSlot(int OSTnum)
{
    int d7;
    int *a0;

    d7 = 0xE01C[OSTnum];
    a0 = 0xE026 + OSTnum;
    if (*0xE026 == 0) // no entries in the list
        return a0;
    if (OSTnum > 0) {
        for (; d7 >= 0; d7--) {
            if (*a0 == 0)
                break;
            a0 = *a0;
        }
        if (d7 < 0) // not found
            return a0;
    } else
        while ((d7 = *a0) != 0)
            a0 = d7;
    *a0 = *E026;
    d7 = a0;
    a0 = *a0;
    *E026 = *a0;
    *a0 = 0;
    (*a0)[2] = d7;
    (*a0)[4] = 0;
    (*a0)[0x10] = unk_881768;
    (*a0)[8] = (*a0)[0xC] = (*a0)[0x20] = 0;
    return a0;
}

void InitOSTs(void)
{
    int *a0, *a1;
    int d7;

    E026 = E028 = E02A = E02C = E02E = 0;
    E030 = 0x7FFF;
    E026 = a0 = AD08;
    for (d7 = 0x3F; d7 >= 0; d7--) {
        a1 = a0[40];
        *a0 = a1;
        a0 = a1;
    }
    a0[-40] = 0; // close up the last value
    CA9E = CAA2 = E1A2 = 0;
    D01E = 0xD45E;
    E01E = 5;
    E020 = 0xF;
    E022 = E024 = 0x3F;
}

CALLS FOR A LEVEL

InitOSTs()
    E026 = AD08; all else 0
    AD08 = AD48
    AD48 = AD88
    ...
GetOSTAtSlot(6)
    E026 = AD48; E02C = AD08; all else 0
    AD08 = 0
GetOSTAtSlot(6) (repeated)
    E026 = AD88; E02C = AD08; all else 0
    AD08 = AD48
    AD48 = 0
[some time later]
GetOSTAtSlot(2)
    E026 = ADC8; E028 = AD88; E02C = AD08; all else 0
    AD08 = AD48
    AD48 = AD88
    AD88 = 0


So the OSTs are a linked list. $FFE026 is the address of the first free entry. The proper name of GetOSTAtSlot is AllocOST, since that's what it's doing. The variables $FFE028..$FFE030 are set by AllocOST only when it is told to. So now the only thing left is to determine which of these variables point to player 1, player 2, etc. and we can finally dive deeper into Chaotix.

All right. As far as I can tell:

$FFFFE028 is initially given to the first player. Since that value needs to be overwritten, it gets copied to $FFFFE034; likewise for Player 2 and $FFFFE036.

Well I give up so I'm asking the board. I think I found the routine to handle button pushes, since it uses the character traits. But I can't disassemble everything because at one point it calls a function loaded from RAM... based on addresses from a list of negative jumps — they jump BACKWARD. No matter what I do, IDA treats them as forward jumps. I've tried different addressing modes, different targets, changing the values to signed; all to no avail. Can someone help me?

All right, if my question can't be answered, could an IDC script do this, and how? I don't know IDC. Thanks.

I just put in the offsets I found based on some of Mercury's info. Thanks dude, these offsets kept showing up and I had no fucking clue what they were; now I can look even closer into this game! thumbsup.png

$0-$1        word    Pointer to next OST in allocator chain
$2-$7        ?        ?
$8            word    X position

$C            word    Y position
$E-$39        ?        ?
$3A            word    Pointer to table 2
$3B-$3F        ?        ?

TABLE 2

$30            byte    Flags
                    BIT        DESCRIPTION
                    0        has sheild?
                    1        ?
                    2        ?
                    3        if 1 then shrunken, if 0 then grown; only checked when $38 != 0
$32            word    Invincibility timer (from $4B0 to $0; $0 == no invincibility; each new box adds $4B0)
$33-$37        ?        ?

$39-$3F        ?        ?


I still have to look into those other offsets, and also into Thorn's data...

Note that the action is initiated by another action (including the sound effect); then the subroutine is jumped to. Offset 7 from the main OST has the value in the comments (byte).

Weird but interesting thing: instead of doing
CODE
    jsr necessarySub
    rts
each time (there are many returns in each subroutine), each of the above subroutines do
CODE
    pea necessarySub
condition_1:
    ; ...
    rts
condition_2:
    ; ...
    rts
It's unorthodox but still cool.

Small break from OST to do object research.

We know the location and type of the object position tale — it's on the SCHG now. Each entry in this list is a list of object entries of the form

CODE
x position - word
y position - word
object type - word
object subtype - word


with a word $FFFF ending the list.

I also started deciphering the object list:

The implementation of each function reads like cuneiform until further notice.

Also the numers should go up by 4. If I made an error, please let me know.

2. By request, here is what I know about how the game loads objects:

At the beginning of a level and at each iteration of the level loop, the following function is called to load up the objects within a certain extent of the current location on screen. The game destroys objects that are off screen (which is why if you scroll far in debug mode the objects disappear for a while). The repeated calls to AllocOST thus create a linked list of level objects starting at $FFFFE02C, with each first word in the $40-byte OST pointing to the next object.

Then the following function is called to execute the code for each object. The objects themselves are state machines which run a single state per level loop iteration.

A lot of these objects are never loaded directly or initially; they might transform into these objects or spawn these objects but for that I have no idea.

Here are the few objects I can't identify:

CODE
; type (subtype) at level x,y of the first time it is seen
4 (0) at Amazing Arena 1 Morning 1857,2732
12 (0) at Amazing Arena 1 Morning 1744,4044
116 (8) at Tutorial 1 Morning 6033,1808
120 (0) at Tutorial 1 Morning 5265,1624
360 (2048) at Speed Slider 2 Morning 4480,568
528 (0) at Botanic Base 4 Morning 841,1619


Objects 4 and 12 are the clock objects. My problem is that while object 12 is where you go to turn on the lights, object 4 is the one that turns on the lights, and vice versa for the clocks that open faraway doors.

The rest are invisible.

I have no idea about 116 or 120: they seem to do stuff, but I don't know exactly what, and replacing the function with a simple rts has no effect.

Objects 360 and 528 both point to the routine

Syntax Highlighted Code: ASM
ROM:00892096 ; =============== S U B R O U T I N E =======================================
ROM:00892096
ROM:00892096
ROM:00892096 sub_892096:                             ; DATA XREF: ROM:00891E46o
ROM:00892096                                         ; ROM:00891E4Eo ...
ROM:00892096                 andi.w  #~$80,4(a6)
ROM:0089209C                 rts
ROM:0089209C ; End of function sub_892096


I have absolutely no idea what the andi operation is doing in this case, and getting rid of that instruction seems to have no effect.

So there you have it.

I'm following this with some interest, so keep it up. As for that last function at 892096, it's obviously disabling something (though I wonder why it doesn't just use bset), so I wouldn't worry about its exact function until you understand more of how the object tables work.

Also, for posterity's sake, how DO you do the negative offsets correctly? I had a similar problem when disassembling something else and never did figure out how to fix it.

I never figured it out. Eventually I just used Jump to Address and an arithmetic expression. Turns out it jumps to a collision layer manipulation routine.

On an unfair note, IDA Pro does seem to allow reverse offset jumping on other processor architectures, though I'm not entirely sure.

I am also very interested in this research.

Could you, by chance, look into subroutines relating to character sprites and animations? I'd love to be able to implement a fully functioning Tails including hand/ring and tails objects.
