ISSD Native v0.6.0-beta.1

Retro broadcast launcher and match options beta for Windows x64, Linux x64,
Steam Deck (AppImage) and Android 8.0+. Supply your own supported retail USA
cartridge dump. ROMs, personal configuration and saves are not included.

Changes

• Original retro football broadcast launcher with shared keyboard, mouse,
  controller and touch navigation; ROM selection, presentation, control presets,
  gameplay options and mods. Full remapping remains available in-game.
• Penalty timing-input correction in the existing optional bug-fix bundle:
  use the current taker's routed input while preserving goalkeeper controls.
• Separate default-off short goal kicks and final-attack protection.
• Team-strength summaries calculated from the applied roster and formation.
• Original, 1, 2, 3, 5, 7, 10, 15 and 20-minute regulation halves for Exhibition,
  Cup and World Series; scenario/training rules remain unchanged.
• ROM-free AppImage with writable XDG state and preservation of user mods.
• Retains widescreen, tactical cameras, touch controls, campaign recovery,
  replay fixes, independent stadiums and Mod Studio from earlier betas.

Downloads and installation

• Windows: extract the Windows ZIP and run ISSDNative.exe with SDL2.dll
  and aot_boot_deny.txt alongside it. Includes the standalone Mod Studio editor.
• Linux: extract the Linux tar.gz and run ./ISSDNative; system SDL2 required.
• Steam Deck: mark the SteamOS AppImage executable and add it to Steam as a
  non-Steam game using a Gamepad layout. Select your ROM in the launcher.
  Use --appimage-extract-and-run if FUSE is unavailable. See
  AppImage guide for state paths and build instructions.
• Android: install the APK (arm64-v8a and x86_64, Android 8+, upgrade code 11).
  The existing development signing certificate is retained.
• Standalone editor and example/Liga MX/World Cup packs are also provided.
• SHA256SUMS.txt covers every uploaded binary/package asset.

Validation and limits

Windows and Linux Release builds and both Android ABI release builds passed.
Feature and integration checks passed, including actual penalty opcodes and
real Exhibition duration initialization. The AppImage completed a 900-frame
no-FUSE headless run with a clean exit. See release validation.
Physical Steam Deck Gaming Mode, Android picker/touch acceptance, four-controller
hardware and full Cup/World Series playthroughs remain pending. This is a beta.

Launcher and packaging adaptations credit Mabec-games/iss-deluxed at commit
54344cb; see upstream adaptations. Launcher artwork
is original. No netplay, macOS or iOS binary is included.

v0.5.0-beta.4 — Widescreen, animation and controller improvements

ISSD Native v0.5.0-beta.4

Widescreen, animation and controller improvement beta for Windows x64, Linux x64 and Android 8.0+. Supply your own supported retail USA cartridge dump; ROMs, personal configuration and saves are not included.

Changes

• Fit Pixel Perfect Aspect Ratio: New Graphics → Aspect Ratio → Fit Pixel Perfect option chooses a tested widescreen width at the largest whole-number scale fitting the viewport (e.g. 480x224 at 4x on 1080p; 426x224 at 3x on 1280x800).
• Gameplay-Only Widescreen: New Graphics → Widescreen Menus → Off keeps menus, title, coin toss and statistics centered at their original width while matches, replays and penalties remain wide.
• Widescreen Environmental Polish: Rain and snow fill wide margins without repeating HUD text; pitch boundary grounds fill margins cleanly without fence/billboard duplication; announcement bars retain original centered width.
• Enhanced Walking and Running Animation: Extended optional enhanced animation to ordinary walking in all eight directions, with interpolation cleanup and displayed animation phase alignment for offscreen actors.
• Controller Slot Reclamation: Immediate reclamation of detached controller slots before delayed SDL removal events, preserving independent attached controllers and reconnect held-input suppression; disambiguates identical controller models.
• Licensing and Project Metadata: Formal GNU General Public License v3.0 (LICENSE) and .recomp.json project metadata for recomp.board.
• Retained Features: Retains responsive touch controls, both tactical cameras, replay edge-player history, campaign card fixes, audio timing, shootout/substitution/campaign fixes, independent stadiums and Mod Studio.
• Bundled Packages: Windows x64, Linux x64 and Android packages include Mod Studio source, licenses and the MEADOW/HARBOR example stadium pack, alongside standalone editor, Liga MX and World Cup 2026 packs.

Installation

• Windows x64: extract the ZIP and run ISSDNative.exe; keep SDL2.dll and aot_boot_deny.txt beside it. The frozen Mod Studio executable is included.
• Linux x64: extract the tar.gz and run ./ISSDNative; requires system SDL2 and compatible x86-64 libraries (tested on Ubuntu 24.04). Bundles include editor Python/Pillow/Tcl/Tk source.
• Android: install the APK (arm64-v8a and x86_64, minimum Android 8), upgrade code 10, retaining the previous beta's development signing certificate.
• SHA256SUMS.txt covers all packaged assets.

Validation

Windows x64, WSL Ubuntu 24.04 Linux x64 and Android assembleRelease builds succeeded. Regression and packaging checks passed with zero failures.
See release validation for details.
Physical four-controller and full human campaign acceptance remain 1.0 work.
No untested macOS or separate SteamOS binary is published.

v0.5.0-beta.3 — Improved touch controls

ISSD Native v0.5.0-beta.3

Touch-control beta for Windows x64, Linux x64 and Android 8.0+. Supply your own
supported retail USA cartridge dump; ROMs, personal configuration and saves are
not included.

Changes

• Clear native A/B/X/Y labels replace misleading fixed action names.
• Eight-direction thumb movement replaces the old nine-cell grid, with a smaller
  circular dead zone, visible diagonal arrows and an active-sector highlight.
• The movement finger stays captured until release, even when sliding beyond the
  drawn pad. SDL finger-array reorder cannot interrupt movement when an action
  finger lifts; multiple touch devices are distinguished.
• A moving thumb indicator shows direction and returns to centre on release.
  Hiding/disabling, layout changes and suspension clear held input. Rotation waits
  for all fingers to lift before accepting input against the new layout.
• Retain both tactical cameras, replay edge-player history, campaign card fixes,
  audio timing, shootout/substitution/campaign fixes and independent stadiums.
• Include Mod Studio and the MEADOW/HARBOR example pack in platform bundles, plus
  separate editor/example and Liga MX/World Cup 2026 packs.

Installation

Windows: extract the ZIP and run ISSDNative.exe; keep SDL2 and the deny list
beside it. The frozen Mod Studio executable is included. Linux: extract the
tar.gz and run ./ISSDNative; requires system SDL2 and compatible x86-64 libraries
(tested on Ubuntu 24.04). Bundles include editor Python/Pillow/Tcl/Tk source.
Android: install the APK (arm64-v8a and x86_64, minimum Android 8), upgrade code
9, retaining the previous beta's development signing certificate.
SHA256SUMS.txt covers the eight binary/package assets.

Validation

Fresh complete regression: 456 tests and 8 subtests passed, 6 skipped, with
no failures. One system-Python Tcl/Tk editor check was skipped in that run and
passed independently afterward; the other five are existing opt-in/fixture
exclusions. Windows/Linux/Android builds, real SDL overlay rendering, clean
package/editor acceptance and APK upgrade/signature checks passed.
See release validation for details.
No physical Android device was connected: automated input behavior and APK build
checks do not certify thumb feel, touch latency or Android gameplay/lifecycle.
Physical four-controller and full human campaign acceptance remain 1.0 work.
No untested macOS or separate SteamOS binary is published.

ISSD Native v0.5.0-beta.2

ISSD Native v0.5.0-beta.2

Beta prerelease for Windows x64, Linux x64 and Android 8.0+. Supply your own
supported retail USA cartridge dump. The packages include no ROM, personal
configuration or saves.

New in this beta

• Add Graphics > Camera: Classic, Tactical 80% (25% more field coverage
  per axis), and Tactical Wide 67% (50% more). These are real expanded-world
  views with additional visible actors, preserving original projection/tracking
  and normal-size score, timer, radar, flags and labels. Camera selection persists.
• Support the tactical cameras in verified pitch gameplay and goal replays,
  including independently authored stadium geometry and local HD artwork.
• Record actual positions and animation descriptors for players omitted by the
  original narrow-view replay. Matching companion history restores those players
  and survives save/load, pause and rewind; stale unrecorded actors stay excluded.
• Keep black World Series/tournament cards centered in True widescreen, extending
  the background without stretching or reflecting the lettering into margins.
• Preserve enhanced-running animation when tactical sprite uploads occur.
• Correct tactical sprite overlap/order, layer windows and color effects, and
  clear auxiliary admission evidence on loading. Optimize unused subscreen sampling.
• Retain all v0.5.0-beta.1 audio, shootout, substitution, campaign, replay,
  expanded-stadium and Mod Studio fixes. Include the rebuilt editor and the
  MEADOW/HARBOR independent stadium example pack.

Downloads and setup

• Windows x64: extract the Windows ZIP and run ISSDNative.exe. Keep
  SDL2.dll and aot_boot_deny.txt beside it. ISSDModStudio.exe is included.
• Linux x64: extract the tar.gz and run ./ISSDNative. Keep the deny list
  beside it. Requires system SDL2 and compatible x86-64 Linux libraries; this
  build is tested on Ubuntu 24.04. Editor source is in mod-studio-source/.
• Android: install the standalone APK or extract the Android ZIP. Android
  version code is 8, with arm64-v8a and x86_64. The existing beta development
  signing key is retained for compatible sideload upgrades.
• Mod Studio: a separate Windows ZIP includes the rebuilt editor and example
  pack. Platform bundles also include source for desktop Python/Pillow/Tcl/Tk.
• Example pack: platform bundles include it under mods/; enable
  Independent stadium examples in the mod list. Open
  mods/independent_stadium_example.json in Mod Studio. A standalone portable
  example ZIP, Liga MX and World Cup 2026 pack ZIPs are also available.
• SHA256SUMS.txt covers all eight binary/package assets.

Validation and limits

Fresh complete regression passed 451 tests and 8 subtests, with 5
documented skips and no failures. Eight packaging/version-gate tests also
passed. Extracted Windows/Linux tactical-camera startup, cross-platform
image/state equality, editor workflows, checksums, and APK version/ABI/signing
checks passed.

Release validation is recorded in release validation;
rendering coverage and measured desktop costs are in
camera validation.

This remains a beta on the path to 1.0. Dedicated behind-goal penalty/shootout
views, management panels, campaign cards and unsupported scenes retain their
original camera. Earlier save formats remain readable, but old replay recordings
cannot recover player motion that was never captured. Independent stadiums remain
bounded by verified native geometry/resource constraints.

Physical Android gameplay/touch/lifecycle and a full human campaign playthrough
with camera switching remain release acceptance work for 1.0. Four-controller
physical acceptance and netplay remain outside this beta's certification.
No untested macOS or separate SteamOS binary is published.

ISSD Native v0.5.0-beta.1

ISSD Native v0.5.0-beta.1

Beta prerelease for Windows x64, Linux x64 and Android 8.0+. Supply your own
supported retail USA cartridge dump. No ROM, personal configuration or saves
are included.

Changes

• Correct audio producer pacing, transfer handshakes and guest audio timing.
• Fix goal-replay edge players and stale animations in non-native aspect ratios;
  preserve saved replay animation history when loading snapshots.
• Repair expanded stadium selection and logical identity through original
  settings serialization, construction, replay and save/load.
• Add bounded independent stadium profiles: shortened pitches, native maps,
  character artwork, palettes and stadium-local HD replacements. Geometry
  enters save compatibility; changed or removed cosmetic resources refresh
  safely through the original transfer/fade flow.
• Improve Mod Studio with geometry and artwork tabs, drag editing, compiled
  previews and initial-camera view, image/HD import, undo/redo, unused-slot
  cloning, portable export and isolated asynchronous Test/Stop.
• Include MEADOW and HARBOR, two same-template stadiums with different lengths
  and newly authored simple artwork.
• Fix Cup shootout completion saves and validate substitutions, extra time,
  original campaign progression and Continue checkpoints. Record natural,
  uninterrupted Cup/World Series investigations separately from accelerated
  regression fixtures.
• Include the latest menu, stadium-background, HD rendering, match shortcut,
  persistence and documentation fixes since v0.4.0-beta.1.

Downloads and setup

• Windows x64: extract the Windows ZIP and run ISSDNative.exe. Keep
  SDL2.dll and aot_boot_deny.txt beside it. ISSDModStudio.exe is included.
• Linux x64: extract the Linux archive and run ./ISSDNative. Keep the deny
  list beside it. Requires system SDL2 and compatible x86-64 Linux libraries;
  this build is tested on Ubuntu 24.04. Editor source is in mod-studio-source/.
• Android: install the standalone APK or extract the Android ZIP. Version
  code advances to 7; arm64-v8a and x86_64 are included. The existing development
  signing configuration is retained for beta sideload upgrades.
• Mod Studio: a separate Windows ZIP includes the standalone editor and
  the example pack. Editor source is also included in the platform ZIPs/archive;
  running source requires desktop Python, Pillow and Tcl/Tk. See the bundled
  docs/MOD_STUDIO_QUICKSTART.md for exact paths and example-pack setup.
• Example pack: the standalone example ZIP can be opened in Mod Studio.
  Platform archives already contain its manifest and dependencies under mods/.
  Enable Independent stadium examples in the game's mod list. Open
  mods/independent_stadium_example.json in Mod Studio to edit it.
• Existing Liga MX and World Cup 2026 pack downloads remain included.
• SHA256SUMS.txt covers every uploaded binary/package asset.

Validation and limits

Fresh full regression passed 430 tests and 8 subtests, with 5 documented
skips; 8 new packaging tests also passed separately. Clean extracted-package
startup, checksums, archive contents, Windows/Linux builds, Android
ABI/version/signing and editor workflow checks passed and are recorded in the
bundled docs/RELEASE_VALIDATION_2026_10_10.md report.

Both custom profiles completed uninterrupted natural matches with genuine goal
replays, halftime and fulltime. Moving and paused replay matrices passed at
native 8:7, 4:3, 16:10, 16:9 and 21:9 with native/HD artwork. Controlled weather,
original-code boundary and scenery checks are labeled separately from natural
playthroughs in the acceptance documentation.

This remains a beta. Independent geometry retains original scenery and template
widths, with shortened lengths in 32-unit steps and native resource budgets.
It does not provide arbitrary stadium architecture or a full decompilation.
Android physical-device gameplay/touch/lifecycle and physical four-controller
acceptance remain unverified. Netplay is not implemented. Optional AI balance
and every stadium/weather/mode combination are not certified.

See docs/INDEPENDENT_STADIUM_ACCEPTANCE.md, docs/SUPPORTED_FEATURES.md and
the bundled campaign, audio, shootout and substitution acceptance records.

ISSD Native v0.4.0-beta.1

ISSD Native v0.4.0-beta.1

Beta prerelease for Windows x64 and Android 8.0+. The project remains below
1.0; netplay is not implemented.

Changes

• Optional eight-direction enhanced running/dash animation, preserving original
  gameplay timing, sprite scale, palettes and depth. Walking and other actions
  retain their original animations.
• Fix modded team names and flags on verified competition screens and moving
  coin-toss panels, including Cup group/next-game and World Series slots.
• Extend coin-toss scenery for 16:10, 16:9 and 21:9 with varied whole fans,
  loaded-artwork checks, native vertical scrolling and one centered television.
• Widen the verified halftime statistics background while retaining the
  original centered card and sprite clipping.
• Remove Ball Outline, including saved legacy enables. Add optional Color Boost
  and adjustable CRT Strength with saved settings and preview support.
• Updated graphics, modding, supported-feature and acceptance documentation.

Downloads

• Windows: extract ISSDNative-v0.4.0-beta.1-windows-x64.zip and run
  ISSDNative.exe; keep SDL2.dll and aot_boot_deny.txt beside it.
• Android: install ISSDNative-v0.4.0-beta.1-android.apk or use the Android ZIP.
  Version code 6; arm64-v8a and x86_64 are included. The existing development
  signing configuration is retained for beta sideloads and upgrade compatibility.
• Optional mod packs: liga_mx_expansion.zip and world_cup_2026.zip.
• SHA256SUMS.txt covers the downloadable packages.

Supply your own supported retail USA cartridge dump. No ROM, personal
configuration, saves or acceptance snapshots are included.

Known limitations

Untouched complete Cup/World Series campaigns, completed draw-to-shootout flows,
physical four-controller matches and Android lifecycle/touch acceptance remain
pending. Optional AI balance and all stadium/mode combinations are not certified.
Widescreen scenery reuses original artwork; it is not newly drawn stadium art.
Binary downloads target Windows and Android; Linux is build-checked separately.

See the bundled supported-feature inventory and acceptance records for details.

Validation

• Full project regression suite: 262 passed, 3 skipped, 7 subtests passed in 1834.47 seconds.
• Windows x64, Linux and Android builds succeeded.
• Packaged Windows executable booted successfully from a clean extraction with isolated configuration and saves.
• Archive integrity, SHA-256 checksums, Windows x64 binaries and both Android ABIs were checked.
• Android signing certificate matches v0.3.0-beta.1; version code advances from 5 to 6.

These automated checks do not replace the pending physical-device and complete campaign acceptance listed above.

ISSD Native v0.3.0-beta.1

ISSD Native v0.3.0-beta.1

A beta prerelease for Windows and Android. This release improves presentation,
controls and exhibition setup while preserving the original match simulation.
The project is still working toward 1.0.

Changes

• Saved P1–P4 controller profiles, in-game button/axis/trigger remapping,
  adjustable stick/trigger deadzones and P1 keyboard remapping.
• Configurable Android touch positions/sizes and a background/resume pause path.
• Exhibition rematch, mark/restart drill checkpoints and a persistent favorite;
  Original, Classic, Casual and custom presets use existing verified game rules.
• A default-off Original Bug Fixes bundle for verified keeper movement, skill-point,
  goal/restart, scoreboard and name-graphics defects. It does not fix every
  reported original-game issue.
• Graphics/readability controls, Original/Sharp/Enhanced presets, integer scaling,
  sharply drawn overlays, optional ball cues, player labels/markers and radar
  placement/opacity/size.
• Safer widescreen animation and scene transitions, a 504×224 ultrawide view,
  and 16:10/16:9/21:9 penalty scenery with the original goal, players and HUD.
• Original formation/substitution, request cancellation and advancing save/reload
  acceptance with AI off/on. Preserve original auxiliary admission during wider
  rendering so stale poses are not revived after management return.
• Read-only AI tracing with bounded per-actor roster/formation/condition metadata.
• Audited supported features, acceptance records and a future netplay design.
  Netplay is not implemented in this release.

Existing four-player local multiplayer, Continue Campaign, backup recovery,
configuration compatibility checks and cartridge password interoperability remain
available. Optional AI/bug-fix switches start off; matching applied gameplay data
and switches are required when restoring checked saves. Presentation preferences
remain independent of the gameplay save context.

Downloads and installation

• Windows: extract ISSDNative-v0.3.0-beta.1-windows-x64.zip into a fresh folder
  and run ISSDNative.exe. Keep SDL2.dll and aot_boot_deny.txt beside it.
• Android 8.0+: sideload ISSDNative-v0.3.0-beta.1-android.apk or extract it
  from the Android ZIP. arm64-v8a and x86_64 are included. Version code 5 supports
  upgrading the previous build with the same signing key; back up saves before
  changing installations. Uninstalling removes app-local data.
• Optional mods: liga_mx_expansion.zip and world_cup_2026.zip are separate
  downloads. Extract into a selected mods folder; they are not enabled by default.
• Checksums: SHA256SUMS.txt covers the downloadable packages.

Supply your own supported International Superstar Soccer Deluxe (USA) cartridge
dump. No ROM, personal configuration, saves or acceptance snapshots are included.
Open the overlay with Escape/F1 or Guide/Home / Back+Start. Original team
management uses SELECT and opens at an eligible stoppage.

Validation and known limitations

• Shared kit overrides now redirect home and away pointers to isolated records.
  Goalkeeper appearance retains the original cartridge's safe hairstyle convention;
  its documentation and tests now match the actual native behavior.

• Checked snapshots retain widened-player animation and pose history so advancing
  widescreen replay resumes deterministically. Older snapshots remain readable.

• Focused checks passed 59 tests; native replay, save/shortcuts, team-change and
  graphics checks passed 27 tests with one optional fixture skipped. Snapshot
  serializer/transactional checks passed after final arithmetic hardening.

• Package checks verify checksums, archive integrity, both Android ABIs and
  absence of ROM/save snapshots. The APK signature verifies and matches the
  v0.2.0-beta.1 certificate for in-place upgrades.

• The original team-change visual pass covers nine stages, 36 viewport runs and
  468 captures at 256/358/398/504 pixels, matching full endpoint WRAM and sampled
  native-center pixels. The shipped name lookup follows the visible replacement.

• Original formation/substitution commits and deterministic advancing save/reload
  pass with AI off/on. Both-team menus, extra-time substitutions, original
  replacement limits and the substituted human-team actor's optional policy
  decision remain unverified.

• Earlier extended penalty acceptance covers actual human and CPU kicks and the
  next turn; completed shootouts, natural full tournaments and every mode/team
  combination are not certified.

• Physical four-controller, Android lifecycle/touch and display acceptance still
  need device testing. Optional AI tuning needs gameplay balance testing.

• Windows, Linux and Android builds are checked. Downloaded binary packages target
  Windows and Android; SteamOS/macOS packages are not part of this release.

• Android retains the existing debug signing configuration for sideload testing.

See the bundled supported-feature and acceptance guides for precise evidence and
remaining limitations.

ISSD Native v0.2.0-beta.1

ISSD Native v0.2.0-beta.1

This is a beta prerelease, with substantial improvements to local play,
campaign progress and optional AI tuning. The project is still working toward 1.0.

Changes

• Up to four local SDL2 gamepads, stable player slots, SNES multitap support,
  disconnect notifications and automatic pause during live play.
• Continue Campaign, autosaves at safe Cup/World Series transitions,
  two recoverable backup generations, and checks against incompatible gameplay
  packs and tweak settings.
• Native password entry/export for all six original campaign password formats.
  Retail password exchange requires the original gameplay configuration.
• Gameplay Tweaks overlay page with independent, persistent, stackable
  goalkeeper and player AI switches. Goalkeeper positioning tracks angled shots;
  CPU off-ball targets use formation roles, current lineup attributes and condition.
  Both default off and apply live.
• Checked, transactional snapshots preserve CPU timing and multiplayer state;
  advancing save/load replay regressions pass.
• Updated guides, regression tests and release packaging.

Downloads and installation

• Windows: extract ISSDNative-v0.2.0-beta.1-windows-x64.zip into a fresh
  folder and run ISSDNative.exe. Keep SDL2.dll and aot_boot_deny.txt beside
  it. Select your own supported USA cartridge dump on first launch.
• Android 8.0+: sideload ISSDNative-v0.2.0-beta.1-android.apk, or extract
  it from the Android ZIP. Both arm64-v8a and x86_64 are included. Version code
  4 allows updating the previous build with the same signing key. Back up your
  data before changing installations; uninstalling removes app-local saves.
• Mods: the existing liga_mx_expansion.zip and world_cup_2026.zip are
  optional downloads. Extract them into your mods folder, then select that
  folder in the overlay. They are not enabled automatically.
• Checksums: SHA256SUMS.txt covers all downloadable packages.

Open Escape/F1 or gamepad Guide/Home / Back+Start for the overlay.
Connect up to four pads and select the original multiplayer player-count option
in Open Game. Human controls are preserved by the AI tweaks. Restore the same
mod/tweak combination when using Continue or loading a checked save.

No game ROM, personal configuration or saves are included. Supply your own
supported International Superstar Soccer Deluxe (USA) dump. Older release
packages do not contain these new features.

Validation and known limitations

• Full project suite: 156 passed, 2 failed, 1 skipped, 7 subtests passed.
  The remaining baseline failures are the appearance-nibble expectation in
  test_mod_rom_patching and kit-sharing validation in test_shipped_packs_validate.
• Final focused AI, menu, configuration, campaign, advancing replay, multiplayer
  and password verification: 34 passed, 1 skipped.
• Windows, Linux and Android builds succeeded. The release packages target
  Windows and Android; no refreshed SteamOS binary is included.
• Four-controller hardware coverage, Android controls and physical-cartridge
  password comparison still need broader device testing. Initial AI tuning
  needs gameplay balance testing; it does not replace all cartridge AI.
• Wider aspect ratios remain experimental; original object culling can leave
  outer-edge actors frozen or incompletely animated. Use 4:3 for the baseline.
• Audio fidelity and complete end-to-end certification of every mode remain
  in progress. Android retains the existing debug signing configuration for
  sideload testing.

See the bundled README and gameplay, multiplayer, campaign and password guides
for controls and save compatibility details.

ISSD Native v0.1.1b

Changelog

v0.1.1b

Highlights

• Vertical Stripes Kit Support (stripes: true): Added native support for striped kit overlays in the mod system. In-game player sprites can now feature vertical stripes on their shirts using the SNES jersey detail table $81:CE8A overlay (e.g. CD Guadalajara / Chivas, CF Monterrey, Club Necaxa, Atlético San Luis, Atlante FC).
• Away Kit & Change Strip Customization: Fixed kit repainting in patch_kit to update both the Home kit pointer table ($82:827A) and Away kit pointer table ($82:82D0), ensuring teams playing as Away (P2, or P1 in away kit) wear their authentic customized uniforms on the pitch rather than falling back to original cartridge palettes.
• Match State Team Resolution Fix: Fixed team ID resolution in issd_bridge.c where RAM byte offsets 0x0DA0 and 0x0EA0 are properly scaled to 0-based team IDs, preventing mismatches in HUD rendering and match overrides.
• Goalkeeper Sprite Integrity: Fixed SNES VRAM sprite table corruption where field player hair attribute bits inadvertently corrupted goalkeeper composite head and glove animations.
• Team Selection & Menu HUD Overlays: Pixel-perfect alignment and positioning for upscaled flags in team selection grid cells, Handicap selection, Tonight's Game pre-match screen, Coin Toss minigame, and in-game live scoreboard HUD.
• Liga MX y Expansión MX Mod Pack (Apertura 2026): Complete 36-team mod pack including all 18 Liga MX first-division clubs and 15 Liga de Expansión clubs (plus 3 historical clubs) updated to Apertura 2026, featuring:
  • Authentic flag pixel art and high-resolution squad photos.
  • Dynamically calculated SNES player attributes for all 720 players.
  • Club América with vibrant canary yellow (#FFE600) and navy blue.
  • CD Guadalajara (Chivas) with authentic red & white vertical stripes on the pitch, blue shorts, and white socks.
• FIFA World Cup 2026 Mod Pack: Official 32-nation mod pack for World Cup 2026 with up-to-date rosters, tactical formations, upscaled national flags, and custom team kits.
• Android Touch Overlay Menu Navigation: Fully enabled touchscreen navigation in the in-game overlay menu. Players can navigate menus using on-screen D-pad buttons (Up/Down/Left/Right), confirm/cancel with action buttons (A/X/Start and B/Y/Select), or tap directly on menu items to toggle settings.
• Android ROM Picker Stability: Resolved crash when selecting a ROM from the system file picker by waiting asynchronously for user selection and executing a clean process restart upon importing ROM/mods.
