52 ported the in-engine streams as picture and sound. The arc's cutscenes are:

• stream 3, Aura chased by Skeith;
• streams 4-6, Orca's fall;
• stream 7, BlackRose;
• streams 8-12, the church and the first Data Drain.

The game puts three more things around them, which an agent has now ported and checked:

• the subtitle window;
• the music before, during and after;
• the effect tasks of streams 5 and 10.

Subtitles

• Where they live. The event's stream is ccEventStream(num, 1) (0x001b5670). When a stream has a table in evStrMsgTbl (0x003112f0, or 0x00311510 in Parody Mode), it makes its own layer at 242 and a fresh ccMessage. It replaces the global ccMsg and leaves it pointing at the freed object afterwards.
• What runs each frame. ccGetStreamDemoMsg gives the note's line (or -1 to close). Change shows it when Movie Text (strWinMode) is on or the line has flag 0x800. Disp draws the window.
• What it does not do. It never reads the pad. At the end it leaves without a last Disp, so the window vanishes instead of fading.
• When a line shows. The scene's task (24) handles the notes before the event task (32), so a line shows on its note's frame. A skip's close arrives one frame later (the stream's task is 33).
• The drawing. The window is the desktop's ccMessage port.

The music around the streams

• The functions. ccSndStreamCtrl (0x0017d190) sets the music before and after a stream, on the area's bank. ccSndStreamBGM (0x0017cb20) plays at event 4's notes, walking strSndTbl (0x0030b950) for streams 3, 8 and 58.
• In the arc.
  • Stream 3 stops the dungeon's music at frame 385 and restarts it fading in after.
  • In the church (play type 3), stream 8's note at frame 366 stops sequence 1.
  • Stream 12's end starts sequence 1.
• A mistake the sweep caught. Streams 112-119 fade to half and back, not out and then half.

Streams 5 and 10's effect tasks

• The shared part. Both keep Func_str0001's ccStrEffectCtrl, which the port now shares as effect::Ctrl, with a cue map per task.
• Stream 10, the first drain (Func_str0300): noise, one-frame white flashes, feedbacks at two scales, and ccBufferReverce, which inverts the frame.
• Stream 5, Skeith and Orca (Func_str0120):
  • feedbacks that hold then fade;
  • fades to and from white and black;
  • the view's divZ set to 500;
  • eight hit marks at the cue objects. Cues 610-614 read two entries past the three-entry hitRot0120a, into jump-table words the EE's float unit takes as 0.

In the runtime

• On the desktop. piney-game plays the scripts' streams with subtitles and music (StreamPlayer::event). Through story:4, streams 4 and 5 show their subtitles on the desktop's setup screen at 30 frames a second.
• In The World. The API for hosting streams there is at the top of piney-game's stream.rs.

Checked

Against the game in eemu:

• Subtitles. test_stream_rs.py subtitles runs ccEventStream over the scenes' notes. The Rust side plays each stream for real:

  • 19 runs: every stream with a table, Movie Text off, Parody Mode, and two skips mid-line;
  • 5,729 changing steps, all matching.

• Music. test_stream_rs.py music: 1,399 scenarios, command for command.

• The effect tasks. test_stream_rs.py effects, with every primitive and rand after every pass:

  • stream 10: 1,257 passes;
  • stream 5: 3,103 passes, including the marks and the divZ change.

  str0001's fixture regenerates byte for byte.

• Re-run in a clean worktree. The stream, desktop, demo and sound suites pass, with the workspace's tests, clippy, fmt and the docs check.

• Shots. Stream 3's "What the...!", stream 5's noise and feedback, stream 7's BlackRose, stream 10's inversion, and streams 4 and 5 with subtitles on the desktop.
