The gate hack (96) and Data Drain (102) break the screen up through the menu's ccNoiz. The port only passed their calls on as Request::MenuNoise, which nothing drew. The events' noise1 and noise2 set interNoiz, which nothing read.

What the game does

The details are on the field UI page.

• ccNoiz (main 0x001bb080). It keeps four frame counters: the raster bands, the sampling, the sampling's fade, and the inversion. Draw counts them down and draws, on layer 241, what the streams' effect tasks draw (57):
  • eight ccRasterNoize bands;
  • ccBufferSampling at 1.0284 and alpha 0x50, then six frames fading;
  • ccBufferReverce.
• What differs from the streams.
  • The bands' row offsets are drawn once, by the constructor.
  • SetNoizRn draws three numbers per band, not four.
  • SetNoiz plays sound 94.
• interNoiz. It is read at the end of Disp:
  • 2 is one burst.
  • 3 in town 4 gives a long sampling every 16th frame.
  • Otherwise there is a one-in-four chance every 64th frame out of the menus, and the noise is off inside one (but 66 and 62).

The port

• piney_desktop::noiz. Band, Sampling and reverse_prim moved out of piney_stream::effect, which now uses them, and Noiz is added. The desktop crate is where the stream and the field UI both reach.
• MenuCtrl::noiz holds the state. disp::noiz makes the menus' calls (with the sound), disp::inter_noiz makes Disp's, and Draw::Noiz goes to layer 241 in render.rs.
• Request::MenuNoise is gone.

Checked

• The stream's fixtures. str0001, str0300 and str0120 still match primitive for primitive after the move.
• noiz::tests. They cover the band height, the sampling's 8 + 6 frames of alpha, and the draw order.
• tools/test_fieldui_rs.py test_inter_noiz.
  • It sets interNoiz 1, 2 and 3 (in town 4 and in town 1) with two rand values, and opens a menu and a ban over the 64th frames.
  • Every SetNoiz call Disp makes, and its sound, matches the game's.
  • It first failed only on the harness's own range, which ended one instruction short of the last call's return.
• The sound on the other calls. The drain's and the hack's SetNoiz calls now log sound 94 on both sides.
• The other suites. All six field UI suites pass.
• gate_hack_shots. It adds 0-noise, the first frame of the hack's noise.
