Yes, I can do it. Its alot of work and I'm in the process of porting other characters first but I may do it eventually. I'm no moderator, and I frequently ponder this question myself, but I'd say post whenever you've got something new. Code (Text): 0043A2CE - 85 c0 - test eax,eax 0043A2D0 - 8b 4e 0c - mov ecx,[esi+0c] // stores geo address in ecx 0043A2D3 - 53 - push ebx 0043A2D4 - 57 - push edi 0043A2D5 - 7e 29 - jle 0043a300 0043A2D7 - 8d 79 18 - lea edi,[ecx+18] 0043A2DA - 8b d8 - mov ebx,eax 0043A2DC - 8d 64 24 00 - lea esp,[esp+00] 0043A2E0 - 8b 47 08 - mov eax,[edi+08] 0043A2E3 - 25 00 00 00 84 - and eax,84000000 0043A2E8 - 3d 00 00 00 80 - cmp eax,80000000 0043A2ED - 75 0b - jne 0043a2fa This little tidbit (the commented one) pushes the location of the geometry loader + key into the register ecx. I'm using this to finish my list of level headers, but if you don't feel like waiting you can use that plus a level/act combination to find the loader in question. Also, if you wanted to port super sonic's frame data to metal sonic you could, but it would mostly break sonic as well.
So, are the animations model independent? I know the data pointed to in that array says what model to use, but if we could find the transformation data or whatever, could it be applied to any model? If we could do that, it would certainly open possibilities.
Yes, this is why the old supersonic hack used sonic's animations. Remember that animations in sadx are per object, there is no skeletal animation system. I have no idea how the game assigns which frames to which model piece, but I'm almost 100% certain its in order of ID.
So, it would be entirely possible to give Amy Sonic's "Surfer Stance" then? :D In other news, I tried looking around the "Metal Sonic & Tails" code, and I found something that checks for Sonic, but disabling it did nothing. However, I DID find this: 03ABDC7C. Set it to 8, and the intro movie will play, 12, the title screen. THIS is the Game Mode I was looking for with the other address.
Through careful manipulation yes, but it wouldn't be (very) practical unless the id's for the character pieces matched up, for instance amy's head would need to have the same id as sonic's head and whatnot, or they at least have the same relative setup and number of ID's. Also, have you come across how the game handles the menu layouts? I've always wanted to change the menu screens around abit to make things abit more refreshing. Also when the game shows the SEGA screens, if you try making the pvr black, the screen still has a white border in the higher resolutions. I've never been able to find (nor did I look very hard) where the BGRA value is stored.
I have no idea how the menus work, I couldn't even find the selected item value! (Except for the Character Select) Some values for the Game Mode address: Code (Text): *0 - Restart Game (Doesn't stop music) *2 - Exit SADX? *3 - Black out screen, game still playing Edit: or in level, disable object collision? *4 - Action Stage (Adventure Mode) *5 - Adventure Field (Adventure Mode) *6 - Clear Screen, Disable movement *7 - Clear Screen, Disable movement *8 - Intro Movie (-> Title Screen) (Doesn't stop music) *9 - Action Stage (Trial Mode) *10 - Adventure Field/Action Stage (Mission Mode) *11 - Return to Character Select *12 - Title Screen + Menus *13 - Restart Game *17 - Jump to Adventure *18 - Story Introduction Screen *21 - Start Credits *22 - Credits
So, above the sound effect filenames, there's a list of .rel files (which don't exist) and the SET/CAM files to use for each act, looking like this: Code (Text): SS05 - Act 5 SS04 - Act 4 SS03 - Act 3 SS02 - Act 2 SS01 - Act 1 SS00 - Act 0 _Adv00.rel - Station Square Then, before that, there's the character ID list: Code (Text): L - Super Sonic (Last Story) B - Big E - E-102 Gamma A - Amy TI - Tikal? K - Knuckles M - Tails EG - Eggman? S - Sonic Note: all of the text lists in SADX are backwards. They start at the end and move towards the beginning. This list mostly matches the character ID's that you can set in RAM, except that Super Sonic is Sonic and IDs 1,4 and 8 crash the game.
The .rel files would be leftovers from the GC version. Lot's of files are stored as .rel. I've found it twice today. First time it was 0B9C4128, second time it was 0B874128. The values of the options should help you track it down. Code (Text): 00 - Adventure 01 - Trial 02 - Mission 03 - Options 04 - Quit Game. edit: After 6 times finding it I can tell you it is always 0B??4128.
I know what .rel files are, it's just strange that their names are still in the PC version. And that's the only place you can find them. 09AD4128. Also, I got Code (Text): 0 - Adventure 1 - Trial 2 - Mission 3 - Mini Game Collection 4 - Options 5 - End Game Code (Text): EAX=FFCD2501 EBX=00000000 ECX=00000001 EDX=09AD412A ESI=09AD4100 EDI=09AD412A EBP=007EE3A0 ESP=0012FD44 EIP=00432A7F Probable base pointer =09AD4100 00432a74 - lea edi,[esi+2a] 00432a77 - call 00431e50 00432a7c - mov [esi+28],al <- 00432a7f - jmp 00432ac1 00432a81 - mov eax,[eax+0c] Edit: Can't find a pointer.
Code (Text): 004157CC - 33 ff - xor edi,edi;clear edi 004157CE - 8b ff - mov edi,edi;move edi to edi? 004157D0 - 66 85 ff - test di,di;test di for 0 004157D3 - 0f 85 4c 01 00 00 - jne 00415925;if not 0, jump 004157D9 - 66 39 3d c0 2d b2 03 - cmp [03b22dc0],di;test for Sonic 004157E0 - 75 38 - jne 0041581a;if not, jump Disabling the jne here and entering Casinopolis as Knuckles resulted in Sonic and Knuckles both spawning and under my control, with the camera focusing on Sonic. Then I jumped with them too close, Sonic died and the game crashed.
This has so much awesome potential. I know there's a way to accept a second controller input, tails in 1p mode can be controlled with one. The only problem is that the game only uses one controller mapping, so if you've got 2 different types of controllers it won't work. I've wanted 2p in sadx since the beginning.
Code (Text): 004157CC - 33 ff - xor edi,edi 004157CE - 8b ff - mov edi,edi 004157D0 - 66 85 ff - test di,di 004157D3 - 0f 85 4c 01 00 00 - jne 00415925 004157D9 - 66 39 3d c0 2d b2 03 - cmp [03b22dc0],di;test for Sonic 004157E0 - 75 38 - jne 0041581a ---- 00415842 - 66 83 3d c0 2d b2 03 02 - cmp word ptr [03b22dc0],02;test for Tails 0041584A - 75 38 - jne 00415884 ---- 0041581A - 66 83 3d c0 2d b2 03 03 - cmp word ptr [03b22dc0],03;test for Knuckles 00415822 - 75 1e - jne 00415842 ---- 004158AD - 66 83 3d c0 2d b2 03 05 - cmp word ptr [03b22dc0],05;test for Amy 004158B5 - 75 1e - jne 004158d5 ---- 004158D5 - 66 83 3d c0 2d b2 03 06 - cmp word ptr [03b22dc0],06;test for Gamma 004158DD - 75 1f - jne 004158fe ---- 00415884 - 66 83 3d c0 2d b2 03 07 - cmp word ptr [03b22dc0],07;test for Big 0041588C - 75 1f - jne 004158ad The only thing left now is figuring out CPU Tails and CPU Sonic. We definitely need to look at the code after these, it likely will tell us more about how the characters work. Edit: Huh, it looks like the order is Sonic -> Knuckles -> Tails -> Big -> Amy -> Gamma. Edit2: Causing the game to not load any characters makes it crash. Which I expected.

oh good I'll be able to use that pointer edit to make big load sonic or just crash. Big needs to come out of the game. srsly
It's funny how the different characters act with Tails' AI. Normally Tails jumps and starts flying to keep up with you, Sonic will do a jump dash when he hits the ground to keep up with you, Amy for some reason hits the ground with her hammer, Big and Gamma are completely hopeless.

First we have Sonic teaming up with everyone (except Tails) in Emerald Coast. Then, Sonic races to save Station Square from a missile attack! Also, I disabled the code to load the Tornado in Sky Chase Act 1, and I died as soon as the level started. Turns out I was spawning inside the dragon boss I left in the level. And everything else can hurt normal Sonic as well. It looks like the camera (and everything else) is programmed to go based on where you are, because the camera only started when I went near the normal starting area. From there everything is based on time. And even if the Tornado isn't spawned, it will show up to get hit by the laser. Oh yeah, loading the Tornado in any other level crashes the game.
Awesome stuff. I love especially how retarded Big looks trying to get up that ramp and failing =P Also, interesting in the Tails video - the lives icon stays as his, and the life boxes work as Tails lives (that are awarded to you correctly), so something somewhere is still keeping track of the original character for the level.
