Pegasus overlay animation (coords, timing, remake): see 39-title-screen-animation.md. The A4-$632E / A4-$6344 tables @ 0x27096 are music-note staff positions, not per-cel pegasus anchors. Remake display is 320×200.

Introclips — verified blit trace (ASM-only, June 2026 re-audit)

This section supersedes earlier prose where it disagrees. Every coordinate and frame index below is quoted from a specific instruction in EXTRACTED/mm2.capstone.annotated.asm or dumped from EXTRACTED/ghidra/mm2_data_00.bin (the DATA hunk, A4 = data_base + 0x7FFE).

1. introclips.32 frame table (decoded from the retail file)

Header: u16 frame_count = 11, u16 depth_or_mode = 3, then per-frame {u16 w, u16 h, u16 flags} (standard .32 image-chunk codec). Verified by parsing the real introclips.32 (6023 bytes):

Frame	W × H	Frame	W × H
0	17×12	6	26×25
1	17×12	7	19×17
2	40×48	8	27×24
3	10×8	9	27×24
4	48×36	10	45×22
5	48×36

2. Blit routine JSR -$7C20(A4) — argument order (CONFIRMED)

Args are C-style, pushed right-to-left on the stack. Reading the lowest stack slot first, the signature is:

blit(long srcPtr, word frame, word y, word x)
        p1           p2        p3      p4

p3 = y, p4 = x — confirmed three independent ways:

• intro.32 @ 0x260B8 pushes #3(p4), #0(p3), frame=#0(p2), ptr(p1) → drawn at x=3, y=0 (matches the known title-art offset).

0260b8  move.w  #$3, -(a7)         ; p4 = x = 3
0260bc  clr.w   -(a7)              ; p3 = y = 0
0260be  clr.w   -(a7)              ; p2 = frame = 0
0260c0  move.l  -$77ae(a4), -(a7)  ; p1 = intro.32 ptr
0260c4  jsr     -$7c20(a4)

• The attract loop (§4) pushes Xtable[i]+8 into p4 and Ytable[i]-1 into p3, i.e. the X table feeds p4 and the Y table feeds p3.

3. Corner-clip loop 0x26A1E (handle A4-$7A2E, frames 0–4)

This is the loop that draws the two clip sprites. It is reached only from 0x26BC4 (logo / copy-protection hold) via 0x26E64 → 0x26B0C → 0x26B14 → 0x26A10/0x26A1E. It is never reached from the interactive menu (§5).

026a1e  cmpi.w  #$3, -$6478(a4)    ; gate counter
026a24  blt.w   $26aaa             ;  < 3 -> just bump gate (no blit)
026a28  clr.w   -$6478(a4)         ;  >=3 -> reset gate, then blit:
; --- TOP clip ---
026a36  move.w  #$8, -(a7)         ; p4 = x = 8
026a3a  move.w  #$8, -(a7)         ; p3 = y = 8
026a3e  move.w  -$647a(a4), -(a7)  ; p2 = frame index
026a42  move.l  -$7a2e(a4), -(a7)  ; p1 = introclips ptr (handle #1)
026a46  jsr     -$7c20(a4)         ; blit TOP @ (x=8, y=8)
; --- BOTTOM clip (same frame) ---
026a4e  move.w  #$8, -(a7)         ; p4 = x = 8
026a52  move.w  #$d8, -(a7)        ; p3 = y = 0xD8 = 216
026a56  move.w  -$647a(a4), d0     ; read frame (still same value)
026a5a  addq.w  #$1, -$647a(a4)    ; frame++  (advances once per iteration)
026a5e  move.w  d0, -(a7)          ; p2 = frame
026a60  move.l  -$7a2e(a4), -(a7)  ; p1 = introclips ptr
026a64  jsr     -$7c20(a4)         ; blit BOTTOM @ (x=8, y=216)
...
026a94  cmpi.w  #$5, -$647a(a4)    ; frame wrap
026a9a  bne.b   $26aa0
026a9c  clr.w   -$647a(a4)         ;  -> frames cycle 0,1,2,3,4
...
026aaa  addq.w  #$1, -$6478(a4)    ; gate++ (the <3 path)

Verified corner coordinates: TOP (x=8, y=8), BOTTOM (x=8, y=216). Both corners show the same frame each pass; the frame index -$647A advances by 1 per pass and wraps at 5 (frames 0–4 only). Blit fires only when gate -$6478 ≥ 3 (i.e. every 4th poll tick), then resets.

These (8,8)/(8,216) values are not invented — they are the literal move.w #$8 / move.w #$d8 immediates at 0x26a36–0x26a52. What was wrong in the remake was the state placement (see §6).

4. Attract loop 0x27096 (handle A4-$7A32, frames 0–10, table-driven)

Separate routine. Callers are copy-protection / alt-boot branches only: 0x27F3A, 0x2808C, 0x28124. Not the interactive menu.

0270a8  ; loop body, i = -$2(a5), runs i = 0..10  (blt #$b @ 0x27144)
0270d4  lea.l   -$632e(a4), a0     ; X table
0270d8  move.w  (a0,d0.l), d1      ; d1 = Xtable[i]
0270dc  addq.w  #$8, d1            ; X = Xtable[i] + 8
0270de  move.w  d1, -(a7)          ; p4 = x
0270e8  lea.l   -$6344(a4), a0     ; Y table
0270ec  move.w  (a0,d0.l), d1      ; d1 = Ytable[i]
0270f0  subq.w  #$1, d1            ; Y = Ytable[i] - 1
0270f2  move.w  d1, -(a7)          ; p3 = y
0270f4  move.w  -$2(a5), -(a7)     ; p2 = frame = i
0270f8  move.l  -$7a32(a4), -(a7)  ; p1 = introclips ptr (handle #2)
0270fc  jsr     -$7c20(a4)         ; blit frame i @ (x, y)
027144  cmpi.w  #$b, -$2(a5)       ; i < 11 ?

Dumped position tables (DATA hunk, big-endian words, 11 entries each):

A4-$632e (X) file off 0x1cd0	A4-$6344 (Y) file off 0x1cba
all zeros → x = 0 + 8 = 8	8 43 61 148 195 221 248 264 264 241 229

The loop blits introclips frame i at (x = 8, y = Ytable[i] − 1) for i = 0..10. Raw Y words: 8, 43, 61, 148, 195, 221, 248, 264, 264, 241, 229. Several Y > 200 on a 320×200 field. Do not treat this as pegasus part placement — use the overlay coordinate table in 39-title-screen-animation.md. Likely title-music note / draw_cell staff positions (see 0x2712E when i = 0).

5. Interactive title menu 0x1062 / 0xF1C — NO clip animation

game_world_boot (0xF1C) and main_loop_menu_hotkeys (0x1062) draw menu text/boxes via -$7b9c, -$7bfc, -$7c62 etc. Neither pushes A4-$7A2E nor A4-$7A32, and neither calls 0x26A1E/0x27096. By the time 0x1062 runs, both introclips handles are freed (0x26534, 0x26338C). The clip pixels left on the intro.32 playfield by the last 0x26A1E blit simply stay frozen; the menu does not cycle them.

6. Remake overlay model (June 2026)

See 39-title-screen-animation.md for full detail.

• Display 320×200; pegasus: intro.32 @ (3,0) + one introclips cel at a time, phases 0–4 at per-part screen coords (not A4-$632E/-$6344).
• Peekers: frames 6, 8, 9, 10 only (frame 7 = letter-hole cel, not used); one random slot; inactive hollows cover-filled before active cel (see doc 39).
• TitleMenu: black + book.32 / menu text — no intro.32 under boxes (Amiga @ 0x1062 keeps frozen VRAM; remake clears black explicitly).
• Logo: black + nwcp.32, X = 10, Y centered on 200 px height.
• Font: Mm2Font8x8.inc via ScreenCompositor; menu strings plain ASCII.

Reverse-engineering notes for the pre-game title / main-menu presentation and its

dedicated .32 tilesets. Verified against EXTRACTED/mm2.capstone.annotated.asm

(June 2026 ASM-only pass). The desktop remake in game/ uses a 320×200

compositor (2× integer scale → 640×400 window).

Asset files

| File | Frames | Frame size | Role |

|------|--------|------------|------|

| intro.32 | 1 | 320×200 | Title background (pegasus / Might and Magic art) |

| introclips.32 | 11 | 17×12 (frame 0–1); larger in frames 2–4 | Title-menu corner animation sprites |

| nwcp.32 | 1 | 300×90 | “New World Computing Presents” splash |

Embedded load strings (CODE hunk, not the DATA-hunk filename table):

| String | PC offset | Used @ |

|--------|-----------|--------|

| intro.32 | 0x26985 | 0x25FCE, 0x26072, reload @ 0x260DE |

| introclips.32 | 0x2697A | 0x26058 → A4-$7A2E |

| introclips.32 | 0x2698E | 0x260DE → A4-$7A32 (second handle) |

nwcp.32 is also in the main resource table (index 8) for the in-game HUD panel

(15-3d-view-and-game-screen.md). The logo splash blits through temp A4-$F4C

sheet pointers inside 0x26BC4, not the Y=166 HUD placement.

introclips frame sizes (decoded from retail introclips.32)

| Frame | Size | Notes |

|-------|------|-------|

| 0–1 | 17×12 | Small corner sparkles |

| 2 | 40×48 | Pegasus leg fragment (matches intro.32 art) |

| 3 | 10×8 | Tiny glyph |

| 4 | 48×36 | Larger art fragment |

| 5 | 48×36 | Mouth alt — not in mod-5 loop | | 6–10 | varies | Peekers (6,8,9,10) + letter-hole frame 7; 0x27096 blits all 11 |

Frames 0–4 are the mod-5 loop at 0x26A1E; they overlay intro.32 at

fixed corners (8, 8) and (8, 216).

Boot call graph (verified order)

Main title boot path (function containing 0x25FCE … 0x26840):

0x25FCE   load intro.32        → A4-$77AE

0x26058   load introclips.32   → (temp, then A4-$7A2E @ 0x2606E)

game_world_boot @ 0xF1C is reached from the main scheduler (0x372 and

related paths), not from the boot fn @ 0x26840. It assumes intro.32 pixels

from 0x260C4 are still in the playfield (plus any introclips pixels

from the last 0x26A1E blit before 0x26534).

| Boot intro | 0x26376 → 0x26BC4 | nwcp palette-fade and corner 0x26A1E clip sessions over intro.32 |

| Handle free | 0x26534 | Free A4-$7A2E — no further -$7C20 blits from that handle |

| A4 field | Role |

|----------|------|

| -$55DA | Phase gate: cmpi #3 @ 0x26D2E; when ≥ 3, exit @ 0x27062 |

| -$6476 | Word table (51 copy-prot records; also palette entries during fade) |

| -$77B4 / -$77BC | Nested-loop palette fade index / 8-byte table @ 0x26ABC |

| -$F4C | nwcp splash bitmap pointer; blit @ 0x26E78, 0x26F4E via -$7BE4 |

| -$7A28 | Hold-phase counter copied into -$55DA @ 0x26F02 |

| -$79EC | Fade-out counter copied into -$55DA @ 0x27054 |

Phase sketch ( -$55DA = 0, 1, 2 then exit):

1. Fade in — palette steps from -$6476 / nested -$77BC table; nwcp

   blit through -$F4C; -$55DA < 2 branch @ 0x26F1A uses alternate

   fade blit @ 0x26F4E.

2. Hold / copy-prot — each outer iteration calls **0x26E64 → 0x26B0C →

   0x26A1E (corner clip blits + palette tick @ 0x26ABC) while the

   user types the protection string; on match, delay 0x32 (50) frames @

   0x26EF8; set -$55DA from -$7A28 @ 0x26F02.

3. Fade out — when -$55DA ≥ 2, multi-blit palette restore @

   0x26F5C–0x27048 (blocking — no 0x26A1E during this wait); wait

   0x28208 @ 0x2704C; set -$55DA from -$79EC @

   0x27054.

Clip blits are not limited to nwcp fade ticks. They run inside the

0x26B0C input loop ( 0x26B14 → 0x26A10/0x26A1E ) at the start

of each -$55DA phase iteration @ 0x26E64, with intro.32 already

on screen from 0x260C4. Blocking palette waits @ 0x26EF8 /

0x2704C do not call 0x26A1E.

Return @ 0x27062: free splash alloc (-$A(A5)), draw one menu line

(font 0x11, y=0xC @ 0x27076) — full C/M/O/P/Q strings come from

game_world_boot/0x1062, not here.

Fade mechanism is palette remapping, not per-pixel alpha. The C port approximates

nwcp visibility with global alpha on a black field.

Clip loop @ 0x26A1E (inside 0x26BC4 only)

Only caller chain (verified — no other A4-$6478 / A4-$647A refs in binary):

0x26BC4 @ 0x26E64 → 0x26B0C → 0x26B14 → 0x26A10/0x26A1E.

Inner loop @ 0x26AF0 until -$7BD2 reports a key @ 0x26AF4.

| A4 offset | Role |

|-----------|------|

| -$6478 | Gate — addq #1 @ 0x26AAA; blit when ≥ 3 |

| -$647A | Frame index; wrap @ 5 (0x26A94–0x26A9C) |

| -$7A2E | introclips.32 pointer (loaded @ 0x2606E, freed @ 0x26534) |

| -$77B4/-$77BC | Palette cycle table stepped @ 0x26ABC each inner-loop tick |

Blit args ( JSR -$7C20(A4) @ 0x26A46 top, 0x26A64 bottom):

• Top: x=8, y=8, frame = -$647A

• Bottom: x=8, y=0xD8 (216), same frame index (increment after top blit @ 0x26A5A)

Song 0x137 on channel 0x4F @ 0x26A6C–0x26A7A. draw_cell

@ -$7C38 @ 0x26A8C: x=8, y=8, frame=0, mode=1.

**After 0x26BC4 returns and 0x26534 frees the handle, 0x1062 / 0x1280 never

call 0x26A1E or blit from A4-$7A2E.** Corner pixels from the last blit remain

on the intro.32 playfield until overwritten (frozen overlay, not cycling).

Table-driven loop @ 0x27096 (music / copy-protection — NOT pegasus anchors)

One-shot loop during copy-protection / create-prompt paths. Uses A4-$7A32 and the word tables at A4-$632E / A4-$6344. Not the idle pegasus wag on intro.32 — see 39-title-screen-animation.md.

Callers:

Address	Context
0x27F3A	Copy-protection input routine ("Class=/Race=/Alignment=")
0x2808C	Copy-protection input — space key
0x28124	"(C)reate New Char…" prompt path (after 0x28716/proto setup)

Uses A4-$7A32 (second introclips load @ 0x260DE/0x260F6, freed @ 0x2638C) with position tables A4-$632E (X, +8 @ 0x270DC) and A4-$6344 (Y, −1 @ 0x270F0).

Blit signature (proven, JSR -$7C20(A4))

From the 0x26A1E corner pair: top blit pushes 8,8; bottom blit pushes 8,0xd8 (0x26A4E–0x26A52). "Bottom" = larger Y, and only the second pushed word changes (8 → 0xd8). So push order is X, Y, frame, sheet and the callee reads blit(sheet, frame, Y, X). In 0x27096:

0270d4  lea.l   -$632e(a4), a0     ; X table base
0270d8  move.w  (a0, d0.l), d1     ; d0 = i*2
0270dc  addq.w  #$8, d1            ; X = X_table[i] + 8
0270de  move.w  d1, -(a7)          ; push X  (first → arg4)
0270e8  lea.l   -$6344(a4), a0     ; Y table base
0270ec  move.w  (a0, d0.l), d1
0270f0  subq.w  #$1, d1            ; Y = Y_table[i] - 1
0270f2  move.w  d1, -(a7)          ; push Y  (second → arg3)
0270f4  move.w  -$2(a5), -(a7)     ; push frame = i
0270f8  move.l  -$7a32(a4), -(a7)  ; push sheet (introclips handle)
0270fc  jsr     -$7c20(a4)         ; blit(sheet, frame=i, Y, X)
...
027140  addq.w  #$1, -$2(a5)       ; i++
027144  cmpi.w  #$b, -$2(a5)       ; i < 11
02714a  blt.w   $270a8             ; loop frames 0..10

Dumped tables (data hunk EXTRACTED/ghidra/mm2_data_00.bin, file_off = 0x7FFE − disp, big-endian words)

A4-$632E X table @ file 0x1CD0 — all 0x0000 for i=0..10 ⇒ X = 0 + 8 = 8 (constant).

A4-$6344 Y table @ file 0x1CBA (the two tables are contiguous: 11 Y-words then 11 X-words):

frame i	raw word	Y = raw − 1	X = 0 + 8
0	0x0008	7	8
1	0x002B	42	8
2	0x003D	60	8
3	0x0094	147	8
4	0x00C3	194	8
5	0x00DD	220	8
6	0x00F8	247	8
7	0x0108	263	8
8	0x0108	263	8
9	0x00F1	240	8
10	0x00E5	228	8

Per-step delay @ 0x27136: push #$4b → JSR -$7BC0 → wait(1) per index.

Two introclips blit sites (whole binary): 0x26A1E (A4-$7A2E, corners @ logo hold) and 0x270FC (A4-$7A32, table loop above). Idle menu 0x1062 calls neither.

Title menu @ 0x1062

main_loop_menu_hotkeys — reached from game_world_boot @ 0xF1C when

A4-$79E4 / A4-$7950 allow (0xFBC / 0xFC4 → 0x1062).

| C | $43 | Create character → 0x1288 |

A4-$79F2 set to $FF @ 0xF7A. Idle menu: retained intro.32

framebuffer (with frozen corner clip pixels from last 0x26A1E blit) + menu

text — no ongoing 0x26A1E loop, no nwcp compositor.

Idle wait: 0x1230 polls -$7BD2; falls through to 0x1258 →

0x1280 scheduler — neither path references A4-$7A2E, -$6478, or

-$647A.

Open questions

• Exact contents of A4-$632E / -$6344 word tables for 0x27096 (11 entries). Resolved — dumped above (X all 0 → constant 8; Y = {7,42,60,147,194,220,247,263,263,240,228}).

• Initial values loaded into A4-$7A28 (hold) and A4-$79EC (fade-out) before

  the -$55DA phase loop.

• Precise menu string positions on the static screen (partial trace @ 0x27076;

  0x103C draws one line @ y=0x26 in another boot branch).

• Whether copy-protection 0x26BC4 typing UI must precede the visible nwcp fade

  on original hardware (same routine).
