Video Clips
Video clips are made out of a sequence of standard bitmaps. The meta-information about a video clip
is stored in resources of type 0x04. This information block refers to the resource that contains the frames, which
is stored in the same resource file.
Contrary to MOVI Resources, video clips contain only the frame information - nothing else.

000C int16 Unknown. TriOp intro: 0x0001, 0x0000 otherwise
000E N*[5]byte Sub-table of N sequence entries
MMMM int16 Unknown. Always 0x010C
Video Clip Sequence Entry (5 bytes)

Video Mails
Video mails are small animated movies sent as mail during the game, all stored in vidmail.res.
A single video mail is split up in several sequences. Most notably, the TriOp intro is a reused sequence for all mails.
The resource file contains 12 such sequences: Per sequence there is one resource of type 0x04
and a corresponding bitmap resource (containing the frames in blocks).
Video mails have a size of 200x100 pixel and are the same for the HD and CD releases. They share the palette of the
game (gamepal.res).
Hardcoded constants
The classic engine has the following hardcoded constants:
- There are 6 video mails, ordered as: "shield", "grove", "bridge", "laser", "explode", and "status"
- "laser" has two sequences, "explode" has five sequences. The twelth sequence is the intro, having index 10, right before the status.
- The first ID for the sequence descriptions is
0x0A4C - The first ID for the sequence bitmaps is
0x0A40
The engine always plays the intro first, then the requested video mail. The bundling of sequences (like for "explode") is hardcoded, so if another video mail could either split itself up, or simply have only one frame (or none at all) at the end.
Cutscenes
The files start1.res, death.res and win1.res contain low-res variants of the corresponding
cutscenes.
The palettes for these cutscenes are stored in cutspal.res.
