- **grounding:** source=investigation, confidence=high
- **evidence:** Ghidra /v2: op_0x20f_play_modal_movie_to_surface@0x422e50 shares the movie-object allocation, DirectShow graph open, audio-route, and volume setup used by 0x236, then calls movie_start_modal_playback@0x463280, ORs EngineCtx+0xa0ce4 with 0x2000, and marks movie presentation dirty. The main loop and window procedure special-case run-state 0x2000. Corpus has exactly three sites: LOGO (0x335f,42,4), OP (0x3364,42,4), and ED (0x3324,42,dynamic flags). Those ids are universal raw SYS4INI indexes for MPEG-pack LOGO.AGF, OP.AGF, and ED.AGF; each script releases its surface only after 0x20f resumes.
Implemented through IHost.PlayModalMovieToSurface. Its operand uses the same native universal packed-id catalog contract as 0x236; the separate host call exists for modal wait/cancel lifecycle, not a different resolver. ResourceMap must retain MPEG signature validation in ReadMovie. Godot reuses the asynchronous decoder/retained-surface compositor, parks only the VM thread until EOF, and treats mouse click or Accept/Cancel input as completion before wrapper cleanup releases the decoder. MPEG audio remains a separate backend/audio-clock contract.

### 0x212 `set-gfx-field64` (set-gfx-field64, argc 2)

- **grounding:** source=investigation, confidence=high
- **evidence:** Ghidra /v2 op_0x236_play_movie_to_surface@0x423ee0 fetches operand 1 and passes it unchanged to movie_to_texture_open_asset_graph@0x463e20, which passes it unchanged to asset_open_indexed_entry@0x44f390. The opener directly indexes the flat base table or selected AAI table and has no scene input. SC0000 native operand capture and exact 0x13c8->0x13d1 trace prove nonblocking behavior. BTL's live 0x2b21 site supplies 0x2af1/0x2af5/0x2bca/0x2bd8/0x2bde, the exact base entries MVB001/MVB004/MVB914/MVB958/MVB955.
The handler requires an existing destination texture, allocates/reuses a 0x478-byte movie-to-texture object for the surface, opens operand 1 through the native universal packed-id reader, builds FilterGraph/IGraphBuilder/IMediaControl/IMediaPosition/IMediaEvent/IBasicAudio, and presents bottom-up RGB samples through the movie texture renderer. Operand 3 selects movie/sound routing policy: bits 0x10000/0x20000/0x40000/0x80000 force sound route 0/1/2/3, otherwise set:DependMovieSound is used; SC0000's low value 2 is retained as native movie mode state. Operand 4 is the movie sync/device mask. Static layer preparation after 0x236 does not terminate the retained movie; 0x21c services it through EOF and subsequent surface cleanup stops/detaches it. The port should type-check the selected packed record as MPEG but must not add a scene base or scene-first fallback.

### 0x238 `set-anim-clock` (set-anim-clock, argc 1)
- **summary:** (duration) — set the GLOBAL animation clock: native ctx+0x51b78=0 (elapsed), +0x51b7c=duration. The generic instruction length is 3 dwords. NON-BLOCKING: only configures; the render loop advances it and interpolates all animating objects. SC0000 opening @0x123bd/@0x13858. Handler 0x4240e0; Kelebek VA 0x422390 is drift.
