Source and layout

• archive.org RequiemAvengingAngel, reqdemo.exe (33,610,789 bytes, sha1 c39e826665850f038fa8dec8961cb0a5b3eb9653), an InstallShield 5 self-extractor. 7z opens it to data1.hdr plus data1..data5.cab, one file group, "Critical Files" (659 files).
• unshield 1.5 fails two files that span volumes, Art\HW\ReqArt3D.art (4.3 MB, the hardware art) and maps\demopp3.jam, and exits 1. tools/is5-extract.js joins the volumes and extracts all 659. The fetcher now falls back to is5-extract when unshield fails, not only when unshield is missing.
• The tree is copied to installed/requiem (guest c:\requiem). Requiem.exe is a launcher: it reads the "current hardware configuration" from the registry (written by Config.exe) and starts ReqDemo_D3D.exe, ReqDemo_3Dfx.exe or ReqDemo_SW.exe. The app runs ReqDemo_D3D.exe directly. No registry and no config needed.
• Miles (mss32.dll) and Atl.dll sit beside it.

Route (headless, --batch-size=100000)

• About batch 200: the title screen (3DO legal text). It idles in a PeekMessage/timeGetTime/IsLost loop, about 40k API calls per batch; that is the wait, not a hang.
• Click 320,240: main menu (single Player 430,102; options; info; quit).
• single Player: Load Game / New Game (New Game about 300,345), with a difficulty drop-down (Purgatory).
• New Game: a scrolling text briefing. Once the text has scrolled off it shows a grid of "P" glyphs and waits. Click 320,240 to start the level. Don't press Enter: in this game Enter opens the console, which swallows the keys.
• About batch 2600: gameplay in the sewer (combat shotgun, 60 shells).
• Verified headless: Up walks forward (into the water, health falls), Left turns, Left Ctrl fires (shells 60 -> 57 per shot, 27 after a hold).
