Command & Conquer: Red Alert (Win95 demo)

Westwood's 1997 demo CD in test/binaries/win98-games-a-d/CnC-Red Alert Demo-SW/. The CD's INSTALL\ directory is the game itself: RA95.EXE (v1.19 demo) runs straight from it, with MAIN.MIX, REDALERT.MIX, REDALERT.INI, RESLIB.DLL and the THIPX16/32.DLL IPX thunk pair beside it. No installer run needed. Registry id red_alert_95_demo (localhost-only), manifest written by tools/gen-win98-games-a-d-manifests.js.

Route (headless, default 200 ms/batch clock)

All mouse coordinates are host canvas coordinates. The game runs a 640x400 mode that we letterbox 40 px down inside 640x480, but GetCursorPos is not letterbox-corrected. A host point (x, y) lands at game (x, y), so to hit something the screen shows at (x, y+40), click (x, y).

batch	action / screen
~96	`timeSetEvent(16ms periodic)` + `Sleep(1000)` timer self-check (see below)
~100000	main menu: Start New Game / Exit Game
120000	click (321,183): Start New Game, then the difficulty slider
170000	click (500,253): OK, then "Choose your side"
200000	click (260,228): Allies, then the mission briefing
640000	click (318,271): OK, then the first Allied mission (snow map, squad + MCV)
900000+	click a unit, click ground: it drives there

Use end-of-run --png-canvas --png= captures. Mid-run B:png: captures came back black on this 640x400 mode, which is a capture-path gap, not the game.

Emulator gaps fixed

THIPX32 _IPX_Initialise. THIPX32 is a flat thunk to THIPX16 and the real-mode IPX driver. Our ThunkConnect32 reports success without connecting, so loading the real DLL jumps into its unfilled thunk table. _IPX_Initialise (cdecl, no args) is a constant-FALSE stub row in api_table.json, the answer of a box without IPX installed. The other _IPX_* exports stay unimplemented: they are only reached after a successful initialise.
Main-thread Sleep between thread slices (lib/thread-manager.js noteMainSleep). At 0x553ad0 the game starts a 16 ms periodic timeSetEvent, Sleeps 1000 ms and compares a tick counter (0x6525bc); an unchanged counter is "There has been a timer initialization error". The CLI re-ran main between cooperative slices before recording the Sleep deadline, so the Sleep returned before the new winmm timer thread had run once.
