    Regarding the Sonic CD symbol lists Clownacy posted above: could someone please explain the format they use?

    With the higher quality image, the device on the right appears to be a Sony product; the logo on the top left of the device is clearly a Sony logo, and the other writing on it appears to be the same as that on other Sony receivers/amplifiers I own from the period. Its definitely not a Teradrive. I'll keep looking for a matching model, but if anything my guess it is actually a video recording set up, and that receiver either has an integrated or attached VCR unit (Betamax or VHS, this was the transition period for Sony). Would have been handy for providing footage for advertisements straight from development versions of games.

    Reposting stuff that I put on the SSRG thread:

    I've been digging through the Sonic 2 Nick Arcade and Sonic CD Gems collection symbols for a bit, among other things, and gathered a little collection of what certain labels were called in the source code:

    • y_vel = yspeed
    • mapping_frame = patno
    • anim = mstno
    • status = cddat
    • subtype = userflag

    Other information:
    • Some of these other symbols were found in other data that hasn't been really properly documented out there yet. There's a whole section other symbols and even older code (I found an earlier version of the Emerald Hill boss and documented it here).
    • Mappings and DPLCs were definitely done in assembly, possibly by hand. Sprite mappings are generally labelled as "XXXXXpat", with labels for each sprite frame generally being labelled as "XXXXXspNN".
    • Tile data is labelled as "XXXXXcg".
    • Sonic 1 special stage maps are labelled as 'rotmaptblN"
    • Zones are referred to by their ID, not their name.
    • PLC lists are just labelled as "ddevNN".
    • There's a function that would load the Sonic 1 collision data if it was in Green Hill Zone, but it relies on how their development hardware worked, hence why it doesn't work in the build we have.
    • An object's main routine index table is labelled as "XXXXX_move_tbl".
    • An object's initialization routine is labelled as "XXXXXinit".
    • An object's main update routine is labelled as "XXXXXmove".
    • A common local label used when a free object slot was not found is ".worknai".
    • There's actually a reference to a totally scrapped boss that appeared to initially been made for Chemical Plant. Said symbols are "vacumeguy" and "bossvac".
    • Due to the nature of them using linking and XREFs, there's actually a couple of reused labels that are, of course, not exported.
    • Sonic CD developers called the functions that refer to the animals being deleted with a bad future set and the badniks being destroyed with a good future set as "friend_suicide" and "enemy_suicide" respectively. I know that English wasn't their native tongue, but I found it amusing.
    • Amy was called "emie" in Sonic CD's source code.
    • The "I'm outta here" in Sonic CD routine is just called "bye".
    Of course, this isn't every symbol that's been leaked out, and I'm lacking on Sonic CD's for now, but it's a good chunk I have documented. This should be helpful on documenting the rest later on. A while ago, I did do a quick test of setting up every label in TouchResponse/pcol here. RAM and object variables aren't set up, though, just the code labels.

    Running a Sonic CD ELF file through objdump with the "-l" option while disassembling adds in the filenames and line numbers.
    The information is there.

    Also, structure variables names are included in the .debug section, including the ones for objects, but I'm not quite sure how to get them extracted.

    A question and a thought:
    • Where do "xspeed" and "yspeed" come from? Is it just the February 1990 footage?
    • I guess I didn't take a full look, but I honestly couldn't tell if "mapdevr" was referring to the Enigma decompression routine or the "write tilemap to VRAM" routine. Thinking about it some more, if mapdevr is EniDec, then I suspect that it the name consists of "map(pings)" + "dev" (I don't know what this is, but it seems to mean compression, given "divdevtbl" et al) + "r" (which I guess means "reverse"). (If it means anything, according to the Sonic Jam symbols linked above, RAM address $F6F4 is called "bitdev_d6".)

    xspeed and yspeed can be found both in the 1990 footage and those structure member names found in the ELF files (still dunno the .debug section format x.x)

    I am certain mapdevr is EniDec. Even if the addresses are for an older build, you can still follow a general pattern with them, and it lines up.

    Yeah, I saw that everything else lines up relative to each other, I just didn't look too closely. Thanks for that!

    I just noticed "xspeed" and "yspeed" in that image above. Is it possible to send me the pictured binary to see if I can make out something from them?

    Contained are an objdump dump, R11A's ELF file, and its .debug section isolated. From the Gamecube version.

    EDIT: I did some more digging, and I think I'm on a lead. Found a thread on this very site asking about extracting debug data from a PS2 ELF (specifically DDRMAX2), which led me to a thread from a different site that successfully did it and explained how. The Gems Collection ELF files on the PS2 appear to have used the same compiler as DDRMAX2, AND I have found an archive of the compiler. Will update soon.

    EDIT 2: IT WORKS! Will post results in a bit~

    EDIT 3: ; )

    Sprite status table variables, it looks like:
    • actno: equals $00. Means "action number" and is the thing we call the object's ID.
    • actflg: equals $01. Means "action flags" and are what we call "render flags".
    • sproffset: equals $02. The sprite's offset in VRAM.
    • patbase: equals $04. The pattern table base address... or mappings address, if you prefer.
    • xposi: equals $08. The object's X-position.
    • yposi: equals $0C. The object's Y-position.
    • xspeed: equals $10. The object's X-speed.
    • yspeed: equals $12. The object's Y-speed.
    • mspeed: equals $14. I'm not sure what the label is meant to be read as; our disassemblies call it "inertia" or "ground velocity".
    Those are consistent with Sonic 1 and 2. The next several differ, suggesting changes in the SST format at some point in the pipeline (see also Sonic Jam and its version of Sonic 3 & Knuckles).
    • sprhsize: equals $16. The sprite's horizontal size, as a radius. Was originally $17; this seems to be swapped with the next one.
    • sprvsize: equals $17. The sprite's vertical size, as a radius. Was originally $16; see above.
    • sprhs: equals $18. The sprite's horizontal size, in dots, it seems. Was originally $19.
      • sprvs, sprvo, and sprho also show up alongside sprhs in the February 1990 footage, but not here. Also, see next.
    • sprpri: equals $19. The sprite's priority; was originally $18.
      • sprhs and sprpri are swapped from Sonic 1 and 2, apparently reverting back to the Sonic 1 prototype format. Perhaps the other out-of-order symbols are also indicative of such changes?
    • patno: equals $1A. The object's pattern number (or mapping frame).
      • patno and mstno actually match the Sonic 1 and 2 code.
    • mstno: equals $1C. Master pattern number, aka pattern change number, aka animation number.
    • patcnt: equals $1E. Pattern counter; was originally $1B (unsure why it was moved; patno is still a byte and $1B is not shown with a value).
    • pattim: equals $1F. Pattern timer counter; was originally $1E.
    • pattimm: equals $20. Pattern timer master; was originally $1F.
    • colino: equals $21. Collision number (size and type); was originally $20.
    • colicnt: equals $22. Collision counter; was originally $21.
    • cddat: equals $23. Not sure what the name means (collision detection data?), but it's the status bitfield. Was originally $22.
    • cdsts: equals $24. Not sure what the name means (collision detection status?), but it's referred to by us as the respawn number. Was originally $23.
    • r_no0: equals $25. Routine number 0; was originally $24.
    • r_no1: equals $26. Routine number 1; was originally $25.
    • direc: equals $28. Direction; seems like the angle value Sonic uses. If so, this was originally $26.
    • userflag: equals $2A. User flags, or what we call the object's subtype. Was originally $28; takes up a word of space.
    • dummy: equals $2C. Dummy padding. Probably was different in the original code ($2A?); note that userflag is already word-sized. There is a size attached to dummy, but I can't make out what it is.
    • actfree: equals $2E. Action numbers free space; basically, custom RAM set aside for each object's use. Probably was different in the original code ($2C?). There is a size attached to actfree, but I can't make out what it is.

    Figured I'd make a follow-up to my previous post in light of new findings:
    • At some point, it occurred to me that mspeed probably means master speed, which, come to think of it, does line up with what we see.
    • dummy takes up 2 bytes and actfree takes up 22 ($16) bytes.
    • Looking at mstno and direc again, I think the blank bytes at $1B and $27 are just automatically-inserted padding that serve to keep 2-byte values at even addresses.
    Something seems off, though; adding everything together, each object has $44 bytes of RAM, which, when accounting for the 2 bytes of lost RAM above, results in there being 2 more bytes of RAM listed than originally existed.

    I thought it was just "move speed", as that holds Sonic's movement speed on the ground.
    Actually, according to the Sonic CD debug info in Gems Collection, they're actually defined as 16-bit words, using a structure that can access the individual bytes via a union. I do know that sometimes, "direct" or "angle" gets used as a full word in Sonic 1, and this does align with how "mstno" or "anim" is used in the original. In the original, SST $1D is used to track animation changes, which was also ported here. Seems like the original never had a separate definition for that, and just added 1 to "mstno".

    Here's the full structure as generated via dwarf2cpp
    Code (Text):
    1.  
    2. struct _anon0
    3. {
    4.     unsigned char actno;
    5.     unsigned char actflg;
    6.     unsigned short sproffset;
    7.     _anon3** patbase;
    8.     _anon5 xposi;
    9.     _anon5 yposi;
    10.     _anon9 xspeed;
    11.     _anon9 yspeed;
    12.     _anon9 mspeed;
    13.     unsigned char sprhsize;
    14.     unsigned char sprvsize;
    15.     unsigned char sprhs;
    16.     unsigned char sprpri;
    17.     unsigned char patno;
    18.     _anon9 mstno;
    19.     unsigned char patcnt;
    20.     unsigned char pattim;
    21.     unsigned char pattimm;
    22.     unsigned char colino;
    23.     unsigned char colicnt;
    24.     unsigned char cddat;
    25.     unsigned char cdsts;
    26.     unsigned char r_no0;
    27.     unsigned char r_no1;
    28.     _anon9 direc;
    29.     _anon9 userflag;
    30.     unsigned char dummy[2];
    31.     unsigned char actfree[22];
    32. };

    "_anon9" being a 16-bit value with individually accessibly byte. Similar for "_anon5", but that's a 32-bit value instead. "_anon3" is just sprite mappings data.

    Code (Text):
    1. union _anon5
    2. {
    3.     int l;
    4.     _anon7 w;
    5.     _anon8 b;
    6. };
    7.  
    8. struct _anon7
    9. {
    10.     short l;
    11.     short h;
    12. };
    13.  
    14. struct _anon8
    15. {
    16.     char b4;
    17.     char b3;
    18.     char b2;
    19.     char b1;
    20. };
    21.  
    22. union _anon9
    23. {
    24.     short w;
    25.     _anon10 b;
    26. };
    27.  
    28. struct _anon10
    29. {
    30.     char l;
    31.     char h;
    32. };

    Things do indeed get padded out for alignment, though.

    Also, the reason why the structures don't have names, is because it appears they were defined via a "typedef struct" in the actual source code, with the name of the structure going after the data to fulfill the typedef, and as such, without a tag assigned to it at the start of the structure, it's treated as an anonymous structure, and thus, their names did not get placed in the debug info. Same deal for unions.

    I know in other programs I've examined, the typedef itself is usually recorded too, is that not the case here?

    Apparently, not with the Metrowerks/CodeWarrior compiler/linker, at least with anonymous structures and unions.

    That probably makes more sense, actually. I just thought "m = master" in light of pattim and pattimm (then again, they probably would have used speedm for that purpose).
    Um, I was saying that bytes $1B - the one in between patno ($1A) and mstno ($1C) - and $27 - the one in between r_no1 ($26) and direc ($28) - are both inserted by the compiler so that mstno and direc, respectively, are aligned to even values (so CPUs with address error problems akin to the 68000 do not suffer). I wondered in the previous post why byte $1B goes unused, and this was my answer.

    The SST variable order does make sense when considering how things are logically grouped; animation/master pattern stuff after the animation/master pattern number, sprite sizes all clumped together... seeing as I mentioned above how Sonic Jam's version of Sonic 3 & Knuckles is 2 bytes bigger than in the original, combined with a change in order between sprhs and sprpri that can be seen in the Sonic 1 prototype and final version, I suspect that the original equate file would have looked something like this:
    Code (Text):
    1. actno       equ 0
    2. actflg      equ 1
    3. sproffset   equ 2
    4. patbase     equ 4
    5. xposi       equ 8
    6. yposi       equ $c
    7. xspeed      equ $10
    8. yspeed      equ $12
    9. mspeed      equ $14
    10. sprhsize    equ $17
    11. sprvsize    equ $16
    12. sprhs       equ $19
    13. sprpri      equ $18
    14. patno       equ $1a
    15. mstno       equ $1c
    16. patcnt      equ $1b
    17. pattim      equ $1e
    18. pattimm     equ $1f
    19. colino      equ $20
    20. colicnt     equ $21
    21. cddat       equ $22
    22. cdsts       equ $23
    23. r_no0       equ $24
    24. r_no1       equ $25
    25. direc       equ $26
    26. userflag    equ $28
    27. dummy       equ $2a
    28. actfree     equ $2c
    ...and when converting to other systems, they just input the sizes without shifting the actual order around.

    I would like to add something regarding ROM sections.

    I've been taking a look at Sonic Jam, and I realized that each game has been split up into different files. In Sonic 1's case, there's "AC.SN1", "ACTTBL.SN1" (also ACTTBL_E.SN1" and "ACTTBL_N.SN1", because Jam has different difficulty settings), "DATA.SN1", and "TBL.SN1". "AC" is the game code, "DATA" holds compressed graphics, tilemaps, and stage blocks/chunks. "TBL" holds collision data, uncompressed graphics, and stage layouts (including special stages), and "ACTTBL" holds object layouts.

    I then took a look at the disassembly, and I noticed that the padding between sections corresponds to how the game was split up in Jam.

    "DATA" starts off with the Sega Logo graphics, and in the original ROM, you can see the padding placed before said graphics.
    Code (Text):
    1.        rept $300
    2.            dc.b   $FF
    3.        endm
    4. Nem_SegaLogo:   binclude   "artnem/Sega Logo (JP1).bin" ; large Sega logo
    5.            even

    The last piece of data in the "DATA" file is the graphics for the logo in the ending, and look at that, another piece of padding right after it in the original ROM:
    Code (Text):
    1. Nem_EndStH:   binclude   "artnem/Ending - StH Logo.bin"
    2.        even
    3.  
    4.        if Revision=0
    5.        rept $104
    6.        dc.b $FF           ; why?
    7.        endm
    8.        else
    9.        rept $40
    10.        dc.b $FF
    11.        endm
    12.        endif

    After this bit of padding is the stage collision data, which so happens to be the "TBL" section
    Code (Text):
    1.        if Revision=0
    2.        rept $104
    3.        dc.b $FF           ; why?
    4.        endm
    5.        else
    6.        rept $40
    7.        dc.b $FF
    8.        endm
    9.        endif
    10. ; ---------------------------------------------------------------------------
    11. ; Collision data
    12. ; ---------------------------------------------------------------------------
    13. AngleMap:   binclude   "collide/Angle Map.bin"
    14.        even
    15. CollArray1:   binclude   "collide/Collision Array (Normal).bin"
    16.        even
    17.        ...

    The last bit of data in the "TBL" file is the graphics for the special stage ring, and in the original ROM, you can see another bit of padding placed after it:
    Code (Text):
    1. Art_BigRing:   binclude   "artunc/Giant Ring.bin"
    2.        even
    3.  
    4.        align   $100

    And after that are the stage object layouts, aka "ACTTBL":
    Code (Text):
    1.        align   $100
    2.  
    3. ; ---------------------------------------------------------------------------
    4. ; Sprite locations index
    5. ; ---------------------------------------------------------------------------
    6. ObjPos_Index:
    7.        ; GHZ
    8.        dc.w ObjPos_GHZ1-ObjPos_Index, ObjPos_Null-ObjPos_Index
    9.        dc.w ObjPos_GHZ2-ObjPos_Index, ObjPos_Null-ObjPos_Index
    10.        dc.w ObjPos_GHZ3-ObjPos_Index, ObjPos_Null-ObjPos_Index
    11.        dc.w ObjPos_GHZ1-ObjPos_Index, ObjPos_Null-ObjPos_Index

    The "ACTTBL" file ends with the last object layout, and, of course, in the original ROM, after that is some more padding:
    Code (Text):
    1. ObjPos_Null:   dc.b $FF, $FF, 0, 0, 0,   0
    2.  
    3.        if Revision=0
    4.        rept $62A
    5.        dc.b $FF
    6.        endm
    7.        else
    8.        rept $63C
    9.        dc.b $FF
    10.        endm
    11.        endif

    Which is then followed by the sound driver after.

    So, based on this info, you can see that the original game had multiple ROM sections: the code ("AC"), compressed graphics, tilemaps, and stage blocks and chunks ("DATA"), stage collision, layouts (both regular and special stages), and uncompressed graphics ("TBL"), stage object layouts ("ACTTBL"), and then finally the sound driver and data. This is why such "useless" padding exists. Each section was aligned.

    Sonic 2 works similarly, but it also adds the "RINGACT" (ring layouts) and "TBL2" (additional compressed graphics, placed between the sound driver + drum samples and music + SFX data) sections.

    So, I was taking a look at the Sonic 2 patent, and I saw this (fyi, yes I know this isn't anything new, but there's just some things I feel like pointing out for the sake of this thread)

    The patent has some pretty interesting things to note. Objects are indeed called sprites, with its structure of variables in RAM being a "sprite status table", which definitely shows where we got that name from. Stuff related to graphics and animation line up with the official variables names as well. The patent also goes into detail about how the corkscrew, pathswapping mechanism, and 2 player mode work, including detail on how the teleportation/swap monitor works.

    From what I can tell, 16x16 blocks are referred to as "graphics (path) blocks", which its associated collision IDs referring to "collision blocks". Chunks don't seem to be referenced, since with collision and path swapping, that all happens on the block level, not the chunk level, so chunks are irrelevant in this case. The loop used to demonstrate the system is basically just a generic image referred to as just an "overlay path". As such, the sectioning shown in these images are on the block level.

    Here's this tidbit from how the corkscrew works I wanna quickly mention. (sloop = the corkscrew in EHZ, called a "shuttle loop")

    The "ride flag" that it refers to is bit 3 in the status SST ($22) for player 1, or bit 4 for player 2. And sure enough, the corkscrew object (Obj06) makes use of this flag to indicate that the player is running on it. Not quite sure why they refer to it or the "hit" flag as separate bytes, though.

    It's great they stayed authentic to their own set of rules, even though it was "just a corkscrew".

    I hadn't seen this patent text before. It's always great to find official names and descriptions. It inspired me to start a page on Sonic CD's sprite status table.

    The patent text actually helped aid my understanding of those variables (for example, connecting "actno" with "action number"), hence why I made this post above (some of the later posts are also worth noting).
