By Biohazard, we had quite a pile to draw from. Its notes name Monster Hunter’s model parser and renderer, Snowboarding’s graphics knowledge, DeadShot’s contact handling, Genesis’s presentation, and services from Wolfenstein, DOOM and Contra.BE02
Parts that fit—and units that did not.
The model format could be reused, but this game called a different floating-point graphics API. Translation and clipping conversion needed their own scale, separate from the basis matrix. Applying another factor to the basis would make the adapted renderer draw the wrong-sized models.BE03
The sound bank also lived somewhere specific: 33 MFi resources inside the second scratchpad slot. Its play(int) argument meant a millisecond seek position. A useful audio decoder still needed to be connected to the right bytes and the right call meaning.BE04BE05
A shorter rectangle changed the camera.
The physical 0.1.0 report reached room 21 with resources loading and audio starting, but the camera conversion used the 240×180 3D clip instead of the full 240×320 canvas. The original game scaled its camera angle from canvas height; clipping should have limited drawing, not changed the projection.BE11BE12
The recorded old room-21 angle matched that wrong conversion. Correcting it put Jill in the staircase corridor in the controlled original-room draw, rather than toward the junk and railing. We kept the original room data and compared fixed positions, so the change we were seeing came from the camera repair.BE12BE13
A controlled original-room host draw retained from 0.1.2, using a specified test position. Jill appears in the staircase corridor. This is not a replay or screenshot of the phone session.

BE90One whole press needs one binding.
Later contextual controls uncovered another mismatch. An action held as numeric 5 could become SELECT when an unrelated input arrived after the game entered a menu. The held Walk/Run shortcut could similarly change key. The 0.1.4 repair kept a native binding for the entire press; the next fresh press could use the new context.BE15
Even the font test had missed what it claimed to check. It changed font scale after constructing the interface. Applying the larger scale before construction exposed the clipped DoJa label, and gave the layout repair a failing baseline it could actually beat.BE16BE20
We kept the shared shell and the useful earlier rendering work. Biohazard made us fill in the gaps around its camera, held bindings and initial font configuration. Those were more pieces the next bridge could benefit from.BE17BE19
About these records
The source explicitly identifies earlier contributions; those credits are not inferred from similar screens. The first projection error is tied to the inspected phone report, while the corrected room image uses controlled host fixture positions. Later input and font repairs have their stated original-method/framework checks. Original game byte preservation and revised-host scope are retained without inventing a new handset replay.

## Prior-work references The recovered Monster Hunter i v0.1.2 checkpoint supplies the DoJa model parser, software renderer and MFi translation foundation. Its bundled Snowboarding work informed the float utility adapter. DMC DeadShot v0.1.2 informed the per-contact input handling. Resident Evil Genesis v0.6.1 informed the dark teal presentation, controls and report tools. Wolfenstein RPG v0.1.0 and Doom RPG v0.1.1 informed system-bar/cutout handling; Contra 4 v0.1.1 informed completed-frame presentation, idle behavior and logging restraint. This title has its own Android package and signing identity.

Entry: `BioMain.start()` creates `b`, installs the DoJa canvas and starts its own game thread. First playable state in the observed route is `b.ah == 8`. The native logical surface is 240x320; the original game centres its 240x240 content at y=40. The bridge aspect-fits this surface and publishes only after graphics unlock. The game uses `com.nttdocomo.ui.graphics3d` and float `util3d` APIs, whereas the previous Monster Hunter runtime uses `opt.ui.j3d`. The adapter preserves the game-supplied float transforms and uses the previous MBAC/MTRA parser. Translation and near/far values are scaled by 64 while the matrix basis uses 4096 fixed-point. Scaling the basis by an extra 64 produces oversized broken models. Keep these contracts separate. Transform indices are row-major (translation 3, 7, 11). Multiply is postmultiply and supports self-aliasing. Float trigonometry is in degrees. `Vector3D.dot(a,b)` is static: matching the descriptor without matching invocation kind is insufficient. `verification/api-invocations.txt` records actual static/instance calls, and `api-refs.txt` records the larger constant-pool reference set.

The `.sp` archive format has a 64-byte container header followed by 2048-byte slot 0 and 115000-byte slot 1. Each slot begins with `ok` and a big-endian payload length. Preserve those slot bytes, including their six-byte prefix. The game itself opens URLs such as `scratchpad:///0;pos=6,length=2000`; URL parsing must accept comma-separated options and bound the read.

Slot 1 contains 33 `melo` sound assets, not separate JAR `.mld` entries. The MFi parser handles these assets, including their PCM samples. Audio completion is DoJa event 3; event 2 means stopped. `AudioPresenter.play(int)` means a millisecond seek position. The game resumes background music using this overload. Android player operations run on a worker, with independent lanes and generation checks to discard stale requests. Spatial `Audio3D` requests are acknowledged; this version does not implement spatial effects.

Version 0.1.1 corrects high-level 3D projection: use full canvas height and centre, independent of setClipRectFor3D. Apply that clip only at flushBuffer, intersecting the active 2D clip. The original b.j(width,height) assigns b.X to height; c.K(room,7) multiplies raw camera FOV by b.X/240. Room 20 is 45° × 320/240 = 60° (MC angle 533, focal 277), and room 21 is 70° × 320/240 = 93.333° (MC angle 876, focal 150). The old 180px-height conversion produced room 21 MC angle 1245/focal 84, matching the phone report. Never resize models or modify player/world positions to compensate for projection. Control labels observe original soft labels and c.fc (Types A/B/C/D). In gameplay b.ah==8 and b.ai==1, the right soft label indicates whether the weapon is raised. The manual text.out entries 306–313 define direction/numeric variants; entries 358–366 supply published soft labels. Labels and help now translate these functions while preserving every mask and control position. The supplied Samsung SM-S938U Android 16 recording/report reaches the third camera and reports 146 resource opens, zero misses, 22 successful audio starts, and zero draw failures. Its single battery reading is not a temperature trend. The revised host checks load and draw rooms 20/21 deterministically with test positions inside the original wall bounds, rather than replaying that phone session. Physical validation of the correction, phone save/continue, full campaign completion, controller analog axes, exact perspective texture correction and spatial audio remain outside the recorded host checks.

Controlled original room draws using identical fixture positions inside original wall bounds. Room20: (-54,0,-5), old MC855/focal155 vs corrected MC533/focal277. Room21: (10,0,-10), old MC1245/focal84 vs corrected MC876/focal150. Before captures use the original v0.1.0 Graphics.java, isolated host classes and original game assets. Corrected room21 puts Jill in the right staircase corridor rather than toward the junk and railing. Corrected room20 enlarges the model to the canvas-based camera scale and moves it onto the matching floor region. Original game/player data remain unchanged; test-only positions are not a replay of the phone session.

WHAT CHANGED 1. Native mappings now belong to a whole held press. Previously a contextual action already held as numeric 5 could turn into native SELECT when an unrelated input arrived after the game entered a menu. Walk/run had the same problem when the selected control family changed. Touch aliases now retain their native binding until release; a later fresh press uses current context. An active directional group also retains its original numeric/native family. Raw original-keypad/physical codes remain exact, and duplicate original key owners remain independent. The retained baseline test fails against v0.1.3 and passes against v0.1.4. No original movement or aiming logic was changed.

3. The title now wraps naturally rather than forcing a two-line heading. This keeps the complete game title and DoJa subtitle visible at the tested 1.3 font scale. No font or button targets were reduced to hide the issue. The earlier font test changed configuration after UI construction and had not actually exercised larger initial text. The strengthened test applies font scale BEFORE constructing the Activity and checks all visible TextViews for vertical clipping and ellipsis. Its pre-fix failure is retained.

- Input regression baseline fails on v0.1.3; all four A/B/C/D mappings, dedicated numeric diagonals, release orders, held context transitions and raw/alias duplicate ownership pass on v0.1.4. - Existing host checks pass: API linkage, 20 models, 33 MFi assets, scratchpad persistence and bounded reads, original game boot/gameplay/movement, pause/resume, room20/21 projection/clipping, zero resource/draw failures, and cooperative guest-thread exit. Host audio uses the existing fake Android player and does not establish phone sound quality. - Stock kit JAR: all 12 Android API 34 framework tests pass under Robolectric. - Integrated Episodes Activity: six Android framework tests pass, including cold construction, attachment/layout in both modes over seven phone/tablet portrait/landscape sizes, minimum button bounds, native aspect and stable renderer, simultaneous pad/action contacts and release orders, physical ownership through mode changes, Back cleanup, independent reports while guest locks are held, safe insets and actual initial 1.3 font scale. - The new keypad test checks all twelve numeric keys, absence of the old SELECT row, real native SELECT center input with another held direction, independent physical/touch ownership, cancellation and the reduced deck. TEST LIMITS Framework tests compile the actual Activity source with a framework icon resource fixture and suppress guest boot through the existing started flag. They do not pretend to execute original gameplay. The APK's actual icon and assets are verified separately. UI previews have an intentionally empty viewport; separate GameRun captures execute the real original game. No physical Android device was connected. Thumb comfort, actual-device controls/graphics/audio/saves, live Downloads export, and Omni return still need device validation. No full-campaign verification is claimed.
