 ==== SEQ16 ====
-Animated images, mostly used for animated mouse cursors.
+Animated images, mostly used for animated mouse cursors, some changeable GUI elements like hey seem to be binary dumps of [[cobjects:CSEQ16_bin]] or [[cobjects:CSequence]] class and they contain complete [[FRM16]] files inside. Unlike Infinity Engine's BAM files, they seem to contain only one animation sequence.
+Surprisingly many .SEQ16 files contain only one frame and therefore are not animated at all.
+==== Header ====
+^ Offset ^ Size ^ Type ^ Description ^
+| 0x00 | 4 | Int | 0x41d80000 - Class ID 1 |
+| 0x04 | 4 | Int | 0x43520000 - Class ID 2 |
+| 0x08 | 4 + dpsz | [[cobjects:DynamicProperties]] | Menu backgrounds store menu position here |
+| 0x0C + dpsz | 4 | Int | Number of frames |
+| 0x10 + dpsz | 4 | Int | Playback speed. Typical value is 0x41700000 |
+| 0x14 + dpsz | 4 + btsz | String | Blit type. Either "Transparent Mask" or "Blend Black Bias" |
+| 0x18 + dpsz + btsz | 4 | | Unknown |
+| 0x1C + dpsz + btsz | 4 | | Unknown |
+| 0x20 + dpsz + btsz | 1 | Bool | |
+| 0x21 + dpsz + btsz | 1 | Bool | |
+| 0x22 + dpsz + btsz | 1 | Bool | |
+| 0x23 + dpsz + btsz | 1 | Bool | |
+| 0x24 + dpsz + btsz | 1 | Bool | |
+| 0x25 + dpsz + btsz | 4 | | X1 |
+| 0x29 + dpsz + btsz | 4 | | Y1 |
+| 0x2D + dpsz + btsz | 4 | | X2 |
+| 0x31 + dpsz + btsz | 4 | | Y2 |
+X1, Y1, X2, Y2 create a bounding box relative to animation origin.
+==== Dynamic Properties ====
+Files without DP store at offset 0x08 only value 0x00000000.
+Menu backgrounds store there count 0x00000001 and a pair String ("Menu Position") and PointInt.
+==== Frames ====
+Frames immediately follow the header. Each frame consists of a bool (1) and a complete [[FRM16]] file.
+^ Offset ^ Size ^ Type ^ Description ^
+| 0x00 | 1 | Bool | Unknown, always? 1 |
+| 0x01 | | [[FRM16]] | Complete FRM16 file |
-They seem to be binary dump of some [[CObject]] and they contain complete [[FRM16]] files inside
