v0.5.0

New: MGS4 Flashbacks tab

• Added a Flashbacks checklist tab for MGS4, sorted in campaign order. MGS4 already had Feats. Flashbacks now joins the F4 cycle alongside it.
• Progress shows unique flashbacks found (out of 222) alongside the raw trigger count, instead of counting repeat triggers as progress.

Overlay customization

• Overlay position, size, UI scale, opacity, initial visibility, checklist height, hotkeys (toggle/tab/scroll keys), and log verbosity are now all configurable in bbtracker.ini.
• Optional mouse=1 enables a cursor, clickable tabs, title-bar close/move, and a resize grip.
• Log level filtering added (off/error/warn/info/debug).

Visual polish

• Bundled the Inter font with FreeType hinting and tabular digits for cleaner, steadier text.
• Base font size raised to 14; panel titles, tabs, ranks, grades, and MGS4 emblem names are now emphasized in bold/semibold.
• Removed redundant borders around scrollable sections; summary values that used to clip (MGS2 campaign/pull-up/special-item strings) now fit their content width.
• Enlarged MGS2 Bluff dog tag rows and dropped redundant MGS2 summary qualifiers.
• Simplified the Peace Walker insignia tab by dropping its progress bar (the count is still shown).

Fixes

• MGS1: fixed the Japanese-version game timer occasionally unlatching, and its time offset is now assigned directly from the known disc serial instead of a clock-based heuristic. Also fixed the tracker sometimes never detecting stats at all on some setups (including under Proton) due to an overly narrow memory scan.
• MGS2: Dog Tags tab now shows only the active chapter (Tanker or Plant) during full-campaign runs instead of mixing both; refined dog-tag availability gates.
• MGS3: Kerotan checklist now follows actual collection-route order (previously just grouped by stage).
• MGS4: overlay no longer breaks after certain scene transitions (e.g. an Act 4 return) by rebuilding it when the game swaps its render target; the displayed career emblem now matches the game's own results-screen pick logic (e.g. LITTLE GRAY vs. CHICKEN priority).
• Peace Walker: fixed a false "grade 5" report from an unresolved camaraderie counter, Heroism intermittently reading as unavailable, submachine gun takedowns not being counted, inaccurate weapon-type naming in the codename panel, and bogus co-op ratio/codename results caused by reading the wrong save object.
• Reduced overlay frame stalls by bounding background discovery scans.

Full Changelog: v0.4.1...v0.5.0

v0.4.1

Fixes

• overlay: auto-fit child panels horizontally, so MGS4 codenames are no longer cut off (f10d226)
• mgspw: size the save snapshot to cover the result time field, fixing the Peace Walker startup crash (12ca7f2)

Full Changelog: v0.4.0...v0.4.1

v0.4.0

Ghost Babel joins bbtracker and MGS2 gains full dog tag tracking in v0.4.0.

New game: Ghost Babel

• Added support for Metal Gear Solid: Ghost Babel (MGS_BC2 via bbtracker_babel.asi), with live career rank projection and counters.
• The panel adopts Ghost Babel's Game Boy Color look: black plates, amber frame, and colors taken from the in-game HUD.
• Projected codenames use the difficulty's own top-rank name (HOUND, DOBERMAN, FOX, or BIG BOSS).

Highlights

• New MGS2 Dog Tags tab: collection progress grouped by chapter, with dog tag variants, tough guards, and story gates. MGS2 now joins the F4 tab cycle.
• MGS2 runs latch at the chapter intro, and the Summary shows stage time with separate pull-up counters.
• Peace Walker tracks stun rod KOs and non-lethal (sleep/stun) explosives in mission and career totals.
• MG1 and MG2 now fall through the full ten-tier codename ladder down to CHICKEN instead of dropping the projected codename on slower runs.

Fixes and polish

• Overlay panels fit the active tab, scale automatically for high-DPI and 4K displays, and stay visible with stats intact through loading and transition screens.
• MGS2: fixed special-item usage tracking, radar-use detection, and Plant campaign labeling; removed the unreliable alert display.
• MGS3's Kerotan checklist is now ordered by stage.
• Peace Walker: weapon categories a mission doesn't use show n/a, unavailable career values are labeled, and the panel got better contrast, spacing, and resizing.
• MGS4's Chicken emblem now appears in the Feats tab.
• MG1 Easy runs allow nine alerts, matching the game.
• Fixed an MGS1 crash on startup and hardened memory reads across every game so scene changes can't cause crashes or stale stats.
• Tagged releases are now also published to Nexus Mods.

Full Changelog: v0.3.1...v0.4.0

v0.3.1

Peace Walker

• Mission timer now tracks the whole mission instead of resetting on area changes.
• Timer freezes at the game's official completion time on the results screen.
• Current-run stats remain visible through cutscenes, loading screens, and mission results, then clear on return to a hub or menu.
• Added current-mission hold-ups, CQC uses, and Heroism.
• Added lifetime CQC uses to Global Stats.

Full Changelog: v0.3.0...v0.3.1

v0.3.0

Peace Walker joins bbtracker as a fully supported game in this release.

Highlights

• Added a Peace Walker overlay with live mission time and stats, projected career codename, grade progress, insignia tracking, and scrollable career totals.
• Added Peace Walker region names plus detailed lethal, non-lethal, weapon, CQC, Fulton, and extraction counters.
• MGS4 now names special items used instead of showing only a total.

Fixes and polish

• Panels now stay aligned when game window size and internal render resolution differ.
• Fixed several Peace Walker readings and projections, including health, codename choice, weapon spread, headshots, and counter labels.
• Fixed MGS2 Tanker–Plant rank tracking and story selection.
• Fixed Kerotan tracking for Graniny Gorki South during The Fear.
• Improved panel colors, sizing, scrolling, incomplete-data states, smoothness, and rendering stability.

Full changelog: v0.2.1...v0.3.0

v0.2.1

MGS3 Kerotan reliability and MGS4 tooling update.

Source changes

• Fixed MGS3 Kerotan tracking by reading the 64-bit hit mask from story-state offset 0x242 instead of a stats-relative address whose pointer spacing changed between rooms and cutscenes and could report false counts.
• Simplified MGS3 Kerotan handling by removing stale-copy accumulation and title-transition workarounds now unnecessary with the stable story-state field.
• Updated current-area Kerotan lookup to accept runtime area-code suffixes such as _0.
• Changed the MGS4 stage selector to launch normally by default. Added None (normal launch) so the mod can remain installed while restarting without a --stage argument.
• Added preliminary Peace Walker Master Collection reverse-engineering documentation covering the target Steam build, protected executable layout, section hashes, static anchors, save observations, and next analysis steps.
• Expanded MGS4 analysis tools with separate Bandana and Stealth Camouflage use flags, Drebin-point fields, and a validated --set-drebin live-memory option.
• Clarified MGS4 research notes for the special-item bitmask and Drebin-related fields, and bumped tracker, stage-selector, and rule-check package versions to 0.2.1.

Verified behavior

MGS3 story-relative Kerotan state was validated in a controlled Virtuous Mission run across pointer-spacing changes. MGS4 save inspection and live-memory write paths include self-checks. Release archives were built for all five game-specific tracker packages, the combined package, and the MGS4 stage selector.

Full diff: v0.2.0...v0.2.1

v0.2.0

MGS4 tracking and Direct3D 12 support update.

Source changes

• Added full Metal Gear Solid 4 tracking for Master Collection Vol. 2, including live projected emblems, rank requirements, run stats, named areas, flashbacks, and a dedicated Feats tab with progress for all 23 special emblems.
• Added MGS4 memory probing for difficulty, alerts, kills, continues, recovery items, special items, play time, CQC, headshots, knife defeats, pickups, hold-ups, searches, militia interactions, movement feats, box/drum time, and weapon collection.
• Added active ranked-run detection for MGS4. Main menu, standalone Mission Briefing mode, and unknown extra-stage families now show no active ranked run instead of stale stats.
• Added Direct3D 12 overlay support alongside Direct3D 11, with automatic renderer selection and MGS4-specific visual styling.
• Added a separate MGS4 stage-selector micro-mod: replacement launcher for direct stage startup plus an in-game F6 stage picker.
• Published a technical MGS4 reverse-engineering reference covering executable layout, linkvarbuf, stat offsets, stage codes, emblem predicates, archive formats, and supporting analysis scripts.
• Moved initial tracker placement to center-left for every supported game and polished MGS4 Feats wording, completion colors, and scrollbar styling.
• Added MGS4 tracker and stage-selector release archives and bumped package/check versions to 0.2.0.

Verified behavior

MGS4 tracking was validated live across multiple areas and counters under Direct3D 12, with Direct3D 11 loading also confirmed. Stage selection, ranked-run exclusions, and named-area mapping were smoke-tested. Cross-compiled tracker and selector builds pass; native rank-rule tests pass for MG/MG2, MGS1, MGS2, MGS3, and MGS4.

Full diff: v0.1.3...v0.2.0

v0.1.3

Ranked-run detection and probe reliability update.

Source changes

• Corrected Metal Gear 2 timer conversion from 30 Hz to 15 Hz and added active-run detection for Metal Gear and Metal Gear 2.
• Improved MGS1 edition detection for western, Japanese original, and Integral discs; added correct regional timer mapping and difficulty handling.
• Hid overlay stats outside active ranked runs across all supported games.
• Moved memory probes off render thread, preventing scan work from stalling frame presentation.
• Reduced MGS2/MGS3 area logging to actual transitions and tightened MGS3 pointer validation.
• Simplified non-Nix Windows build setup, added direnv support, removed obsolete Proton override tooling, and bumped package/check versions to 0.1.3.

Verified behavior

All four ASI packages were built and deployed; all five supported games were smoke-tested in game. Native rank-rule tests pass for MG/MG2, MGS1, MGS2, and MGS3.

Full diff: v0.1.2...v0.1.3

v0.1.2

MGS3 tracking and overlay update.

Source changes

• Added MGS3 area-code names and a per-area Kerotan marker (x or -) beside the N / 64 total.
• Changed the MGS3 Kerotan read offset from 0x31D6 to 0x6532. The probe now waits for a post-title stats-block replacement, ignores the transition fill pattern, unions valid masks across runtime copies, and rotates the final 64-bit mask by one bit for checklist order.
• Corrected MGS3 special-item bit labels to Stealth Camo, Infinity Face Paint, and EZ Gun.
• Moved area text below the stats table, changed game-window alpha from 0.96 to 0.80, and added square, themed MGS3 scrollbars.
• Expanded README project scope and feature documentation, documented current Kerotan probe behavior and Snake's Revenge research, and bumped Nix package/check versions to 0.1.2.

Verified behavior

Kerotan counter was tested in game and is functional. After loading a save, count remains empty until game replaces title stats block, normally after one screen transition.

Full diff: v0.1.1...v0.1.2

v0.1.1

MGS2 overlay update.

Changes

• Added sea louse status as YES or NO to MGS2 live-statistics rows.
• Added numeric clearing escapes count beside existing health, times seen, mechs destroyed, pull-ups, and alert-state rows.
• Both values were already read by MGS2 memory probe and consumed by special-rank rules; this release makes them visible in overlay.
• Bumped Nix package and rule-check versions from 0.1.0 to 0.1.1.
