Cutscenes

Depending on the version of SA2, the data for the event cutscenes can differ. EXXXX.PRS is the main file, while the _0 to _J files contain miscellaneous resources, such as audio timings and lighting/screen fade information. In the Dreamcast version, the models and animation data for a scene are all contained within the main file, while in SA2B, the animation data was split off into an uncompressed file labeled exxxxmotion.bin. With two exceptions in the DC version - those being E0203 and E0210 - the event files can only be interpreted by the game if the main file is compressed.

Files that are labeled as evmes??.prs contain the subtitle text and their assignments per cutscene. The first ? wildcard starts with either H, D, or L, denoting the text used for the Hero Story, Dark Story, and Last Episode respectively. The second ? wildcard contains a number from 0 to 5, which represents the language. As an example, evmesH1 contains all the English subtitle information for the Hero Story cutscenes. The contents of these files can be edited using SA2CutsceneTextEditor.

1C	UINT32	Scene Frame Count	"Scene 0" will contain the total number of frames for the entire cutscene, as its section stores the cutscene geometry and must remain visible at all times.

Scene Entity Arrays

This section of the cutscene entity data array controls which models and animations are to be loaded as a singular entity in a scene. The contents of this section are slightly different between game versions.

Upgrade list

The upgrade list is constant throughout the game. To work around a technical limitation with the character models in SA2B, Mech Tails and Mech Eggman were given an upgrade slot each for their windshields, as they would have problems rendering otherwise.

2	Sonic's Flame Ring

17	Mech Tails' cockpit window (SA2B only)
18	Mech Eggman's cockpit window (SA2B only)

Mech Parts list

The list used to detect mech character parts is constant throughout the game. The way this list works is that each part of the mech is referenced via pointer to its OBJECT struct and pieces that are deemed redundant are rendered invisible. For example, if the player has acquired Mech Tails' Bazooka upgrade, his Vulcan Cannon won't render on his model and vice versa.

The list is essentially split into three sections, with the first two including pointers to the upgrade models and the last section focusing on the regular models if they exist. The order of the upgrades in the list is identical to a set of flags that are found in the game's code, which is the basis for the descriptions found in the table. The Tornado object in E0004 references its Vulcan Cannon where the Bazooka upgrade would normally be referenced. The reasoning for this is unclear at the moment.

The original purpose of this section was to serve as the upgrade application list for cutscenes. As such, all visible upgrades are supported here, but due to the inclusion of a new upgrade list that more closely matches the in-game implementation, the mech characters are the only ones to utilize the feature at all.

Character Node Hierarchy

The node hierarchy for the characters in the cutscenes tends to be quite different from their main game counterparts. As a result, there isn't so much a common skeleton for the cutscene models so much as a different arrangement for the same nodes, with some alterations for what's included within the body's mesh. As a general rule of thumb, any part of the mesh that requires shape motions in the scene is not included with the main model.

EXXXX_0 Information

In earlier version of Sonic Adventure 2, the event files that had an additional number as a suffix contained all the additional data for the cutscene. The final builds adjusted this system so that the various languages would utilize files that only contained their subtitle and audio timings. EXXXX_0 was originally meant to contain data related to the Japanese language setting, but the final builds repurposed them to contain and load the external graphical effects used in each cutscene.

Screen Effects

Information starting at 0x9800 denotes any screen effects that occur within the scene, such as fades or color changes. Each chunk of this information is 64 bytes long, with the last 32 bytes acting as a buffer. There are a total of 64 possible entries that can be implemented for this section.

Offset	Type	Description
0	UINT32	Frame in which the screen information takes effect
4	Byte	Effect type ID Description 1 Screen fade-in 2 Screen cut-in 3 Texture fade-in 4 Texture cut-in 5 Background fade-in 6 Background cut-in

*Custom particles treat these values as depicted in the list, while normal particles treat these as displacement values

Object Lighting Information

Starting at 0x26800 are 68-byte chunks that dictate the object lighting information for the corresponding cutscene. The last 20 bytes can be considered a buffer for now. Lighting information is split into four sections of 256 entries each and all four sets are combined at runtime, depending on the entity flag settings. The Dreamcast version only applies the first section's information by default unless the multi-light entity flags are set, while SA2B applies all four lighting sets at all times. "Scene 0" entities ignore all lighting instructions by default unless the multi-light entity flags are set. There are a total of 1024 possible entries that can be implemented for this section.

Offset	Type	Description
0	UINT32	Frame in which the lighting information takes effect
4	UINT32	Fade control. 1 is a hard cut, while 2 is a fade-in from the previous set of instructions

3C	UINT32	Unknown

Video Overlay Information

Information starting at 0x39800 determines whether or not an FMV overlay is meant to be loaded in a scene. Depending on the settings, the video can either be superimposed over the screen, or a mesh that's in the cutscene. The chunks are 64 bytes long, with the last 16 acting as a buffer. There are a total of 64 possible entries that can be implemented for this section.
In the Dreamcast and GameCube versions, .m1v files are loaded for these cases. The 2012 re-release checks for and loads the .sfd equivalents of the video overlays.

Offset	Type	Description
0	UINT32	Frame in which the video begins to play
4	INT16	X Position. Positive values push the video overlay to the right.
6	INT16	Y Position. Positive values push the video overlay down.
8	Float	Depth value. A higher value means the video overlay will be pushed further away from the screen
C	Byte	Overlay type ID Description 0 Null 1 Screen overlay 2 Mesh overlay 3 Screen overlay 4 Screen overlay 5 Pause video 6 Resume video
D	Byte	Overlay texture ID*. Any meshes that use the texture ID denoted here will have the specified texture replaced with the video.

The start of the file contains subtitle data. Each data set is 8 bytes long and is tied to the subtitle order found in the appropriate evmes?? file.

There are a maximum of 256 subtitle entries per cutscene.

Offset	Type	Description
0	INT32	Frame in which the subtitle is set to appear. A value of -1 in this slot indicates that the subtitle will be used as the opening text crawl for the cutscene.
4	UINT32	Number of frames in which the subtitle is to remain onscreen.

Information starting at 0x800 and continuing until the end of the file contains audio timings for voices and BGM for each language. Each chunk is 72 bytes in size. Voice clip playback is determined by the cutscene ID, so a value used by E0000 will not be the same as the value used by E0102, for example.

There are a maximum of 512 audio entries per cutscene.

Offset	Type	Description
0	UINT32	Frame in which the audio clip begins to play
4	Byte	SFX initializer. FF is considered a null value and is ignored
5	Byte	Credits initializer and scroll speed control. This is hardcoded to only work with E0210. FF is a null value
6	UINT16	Number of the voice clip that's to be loaded if applicable. This number is added to a default value set by each cutscene and the result is compared against a master array to load the desired voice clip. FF FF denotes a null entry
8	Text	Name of audio track that's to be loaded, if applicable. Placing a hex value of 30 in this spot will stop the current audio track from playing
18	Text	Name of jingle that's to be loaded, if applicable. No cutscenes appear to use this feature

Mini-Event Scenes

Scenes that are labeled as MEXXXX.PRS in the event files are cutscenes that occur within a game state, such as before certain boss fights like Big Foot and Flying Dog. The contents of these files are not as robust as those of the main cutscenes, often only containing animation and shape motion data for the designated characters. As these scenes rely on the player models, specific parts of their body are omitted and replaced with cutscene-specific variants for the duration of the scene, with the exception of Mech Eggman as he only requires animation data. The contents of these files can be broken down as follows:

Offset	Type	Description
0	UINT32	Character flags
4	Pointer	Camera information
8	Pointer	Sonic's pointer array (if applicable)
C	Pointer	Shadow's pointer array (if applicable)
10	Pointer	Mechless Tails' pointer array (unused)
14	Pointer	Mechless Eggman's pointer array (unused)
18	Pointer	Knuckles' pointer array (if applicable)
1C	Pointer	Rouge's pointer array (if applicable)
20	Pointer	Mech Tails' pointer array (unused)
24	Pointer	Mech Eggman's pointer array (if applicable)

For Sonic, Shadow, and Knuckles' player models, any models attached to nodes 42 (Left Hand), 47 (Mouth), 49 (Head), and 61 (Right Hand) will be omitted for the duration of the scene. Rouge only omits models attached to nodes 47 and 49.

The order for each character's pointer array always begins with the player model's animations, followed by the model -> animation -> shape motion data sets for each cutscene model. The head's data goes first, followed by the mouth, then the left hand, and finally the right hand.

The DC base pointer for these scenes is 0xCB00000
The base pointer for these scenes in SA2B is 0x816DFE60

Much like the _1 to _J files for the main event cutscenes, MEXXXX_0 to _5 dictates audio and subtitle information for the mini-event scenes. These files are uncompressed.

The start of the file contains subtitle timings and their duration. Each data set is 8 bytes in size and is tied to the subtitle order found in the appropriate evmes?? file.

There are a maximum of 32 subtitle entries per cutscene.

Offset	Type	Description
0	UINT32	Frame in which the subtitle is set to appear
4	UINT32	Number of frames in which the subtitle remains onscreen after it has been loaded

Information starting at 0x100 contains timings for each language. Each chunk is 76 bytes in size. Note that voice clip entries are dependent on the cutscene's internal ID, so the "first" entry of ME0001 isn't the same as the one found in ME0007, for example.

There are a maximum of 64 effect timings per cutscene.

Offset	Type	Description
0	UINT32	Frame in which the instruction is set to begin
4	Byte	Screen control. 1 is a normal fade-in, while 2 maintains the screen fade tint until the mini-event is finished.
5	Byte	Sound effect ID that is to be loaded, if applicable. FF is considered a null value
6	Byte	Unknown
7	Byte	Null (00)
8	UINT16	Number of the voice clip that's to be loaded if applicable. This number is added to a default value set by each cutscene and the result is compared against a master array to load the desired voice clip. Valid entries are written as 00 ??, while FF FF is a null value.
A	Byte	BGM control. Setting this value to 2D (45) will cause the level's music to play at the frame specified.
1A	Byte	Jingle control. No cutscenes use this feature by default
2C	Float	Rumble power. This determines the strength and duration of the rumble feature
