This follows 121 with Func_str0150, Func_str0240 and Func_str0250 (streams 7, 8 and 9).

The tasks

• Func_str0150 (stream 7).
  • Cue 899 fades to black over the frames left.
  • Cue 500 is effTransferStr: the arrival's rings (stream effect controller -2) at the note's object, for a character 160 high.
  • It also sets a fog and takes one object out of it. Fog is not drawn by the port.
  • The port raises the transfer as Request::Transfer and does not draw it, as it does with the hit marks.
• Func_str0240 (stream 8).
  • Eight hit marks, one counter over cues 600-605, 610 and 611, each taking the next row of hitRot0240.
  • The table has seven rows. The eighth mark reads the string "OBJ_trall" that follows it as degrees. The port reads the same eight rows from the executable, so its eighth rotation matches the game's.
• Func_str0250 (stream 9).
  • A hit mark.
  • Fades from white on the 900s, and to white at the end.
  • Feedbacks: plain; ready to fade over 15 frames; and turned.
  • The noise and the inversion.

The turned feedback

SetReflex(scale, roll, colour) keeps a turn at +0x0c. Every earlier task passed 0. MakePacket turns its matrix with sceVu0RotMatrixZ before setting the translation, so the picture turns about the view's centre.

• piney_desktop::noiz::Sampling now has roll.
• piney_data::anim::rot_z_bits_of is the EE-exact RotMatrixZ, which rot_bits_of now uses for its first step.
• Stream 9's cues 910-930 turn the picture by 0.00697 radians.

The harness

• The task's end. Func_str0150 never looks at the scene's state. It leaves only when the next scene's ccSetStreamDemoThread sets param[1], and after ccDeleteThread it breathes forever. The harness now sets param[1] at the end as well, and treats ccDeleteThread as the end of the run: the hook raises and the call stops.
• The packets. Their work comes from an arena emptied after each pass's lists are decoded. Stream 7's 2,200 frames had run the heap out.
• Regenerated fixtures. With these changes every earlier fixture comes out the same except for the new header line.

Checked

• crates/piney-stream/tests/effects.rs plays streams 7, 8 and 9 against the game's tasks. Every pass matches by hash, as do rand after it and each mark's and transfer's object and bits:
  • stream 7: 2,203 passes, 32 primitives;
  • stream 8: 1,583 passes, 82 primitives, 8 marks;
  • stream 9: 3,563 passes, 4,586 primitives.
• The workspace's tests, clippy and fmt pass. The field menu's noise (roll 0) is unchanged.
