AM2R Android — 1.5.5.14

AM2R Android — 1.5.5.14 (Full Release)

Touch-control adjustment and Retroid Dual Screen Add-on support.

Standard Edition

• New Diagonal Aim Size slider adjusts diagonal aim arrows and the joystick
  within the same control area. Overall control scale and spacing stay separate.
• Touch targets follow the visible controls, and the controls menu now scrolls
  far enough to show Done.

Dual Screen Edition

• New Dual Screen Add-on option in the Retroid Pocket Duo / Duo Lite profile.
  Enable it for Retroid Pocket Nova with the Retroid Dual Screen Add-on: gameplay
  uses the external 16:9 panel, with the map and menus on the handheld.
• Gameplay fits the external panel correctly when the two displays have different
  aspect ratios. Nova add-on operation is confirmed through community testing.
• The option defaults off for ordinary Duo/Duo Lite setups. RG DS keeps its
  separate screen-order setting, and existing preferences are preserved.

Includes the fixes, translations and Nano improvements from 1.5.5.13.

Updating
Install the new Autopatcher, select your original AM2R_11.zip and rebuild the
edition you use. Install the generated APK over your existing game. Updating
only the Autopatcher does not update an already installed game.
Package IDs and signing are unchanged. Back up your saves before updating and
do not uninstall the game. Standard and Dual Screen remain separate applications.
Both game packages use version code 1005014; the Autopatcher uses version code 18.
The title-screen content version remains V1.5.5.

AM2R Android — 1.5.5.13

AM2R Android — 1.5.5.13 (Full Release)

Nano refinements, translations and lower-screen HUD improvements.

Both editions

• Translated the new Android settings and repaired menu layouts across the
  existing language selection, using the original community fonts. (new android and dual screen features were added using a translator)
• Long help text stays within the original menu strip and scrolls when needed.
• Nano reduces decorative pipe bubbles and pauses distant crabs; nearby combat
  remains active. The darkest Industrial Complex breeding grounds stay visible.
• Reduced unnecessary work around burrowing enemies and the reactor escape.
• Includes the water crash fix and the gallery fixes from earlier updates.
• Corrected the post-reactor Energy Tank map marker; affected saves repair it
  when re-entering the room.
• Extra modes start locked on fresh profiles again. Earned progress and the
  existing secret unlock code are preserved.

Standard Edition

• Native 3:2 joins 4:3 and 16:9 without stretching the artwork.
• Retains touch-control spacing/scale sliders and orientation options.

Dual Screen Edition

• Localized lower-screen actions and area titles, with corrected fonts, timer
  punctuation, controller hints and compact 4:3 HUD spacing.

AM2R Android — 1.5.5.12 hotfix 1

AM2R Android — 1.5.5.12 Hotfix 1

Gallery images restored in Standard and Dual Screen.

Fixed

• Unlocked gallery images could appear blank after selection. The gallery now
  displays the correct ending artwork in both editions.
• Existing gallery unlocks, image fades and confirm-to-close controls are kept.

Includes the UI and lower-end hardware performance improvements from 1.5.5.12.
This hotfix does not change normal gameplay, controller mappings or save formats.

Updating
Install the new Autopatcher, select your original AM2R_11.zip and rebuild the

RG DS community testing reports reduced speed and reversed screens on GammaOS;
those issues are separate from this gallery fix and remain under investigation.

AM2R Android — 1.5.5.12

AM2R Android — 1.5.5.12

New UI and performance improvements on lower-end hardware.

Both editions

• Improved frame pacing, exploration and rendering efficiency to reduce slowdown
  and map-cell stutter.
• Faster texture loading when returning to the game.
• Title scrolling follows the music timing on slower hardware.

Standard Edition

• Smooth Touch Control Scale and Control Spacing sliders, with automatic
  camera-cutout clearance.
• Landscape, Portrait and Automatic orientation options. Surface Duo users
  should keep the game in an unspanned app window on the intended panel.
• Retains the Hold-mode touch fix for selecting Super Missiles.

Dual Screen Edition

• Redesigned lower HUD with blue energy bars, clearer ammunition and Metroid
  counters, and compact controller hints.
• New HUD made by Carlo "AbyssalCreature": https://www.artstation.com/abyssalcreature
• Uncollected ammunition panels stay hidden until the upgrade is acquired.
• Consistent map and menu buttons with either HUD Screen Position. The separate
  HUD Style option is removed.
• Corrected long area titles, Genetics Laboratory naming and GF Research Site
  artwork. The Tower exterior title follows its area scan; Waterfalls now has
  its title across the area.
• Preserves audio when leaving and returning to the game.

Tested devices
AYN Thor, AYANEO Pocket DS, Retroid Pocket Duo and Retroid Pocket Duo Lite are
tested and working, including community feedback. RG DS still awaits physical
validation.

Compatibility
Some Cocoon setups may reduce performance because the launcher continues running
behind the lower display, particularly at low clock settings. The lower display may still take a moment to resume at low clocks.
Compatibility with 16 KB-page devices still needs physical validation; see README.md.

Updating
Repatch your original AM2R 1.1 Windows ZIP and install over the existing edition.
Package IDs and signing are unchanged. Do not uninstall the game first; updating
keeps its saves and settings. Backing up first is recommended. Both game packages
use version code 1005009; the Autopatcher uses version code 13.
Updating the Autopatcher alone does not update an already installed game.

Downloads
Includes the Autopatcher APK, three source archives and SHA256SUMS. Complete
playable game APKs are not distributed. Source licenses and build requirements
remain documented in each archive.

AM2R Android — 1.5.5.13 Beta

AM2R Android — 1.5.5.13 Beta

[ISSUE] .13 beta can't render water correctly and it will shoot an error trying to show water on screen. Please downgrade to .12 until this is resolved

Nano mode and performance improvements for lower-end hardware.

Both editions

• New Nano option in Display reduces decorative effects and rendering work while
  keeping normal game speed, combat and controls. Disable it for full visuals.
• Includes the gallery fix from 1.5.5.12 Hotfix 1 and earlier UI improvements.

Standard Edition

• New Aspect Ratio setting offers 4:3, 16:9 and native 3:2 without stretching.
  During gameplay, changes take effect at the next room transition.

Dual Screen Edition

• Swap Displays for the RG DS profile corrects reversed screen order.
• First-time RG DS setup starts Nano enabled and lets you confirm the screen order.
  Both settings remain adjustable; updating preserves your existing choices.
• More efficient lower-screen map and HUD updates, including in Nano mode.

Compatibility
RG DS community testing has used GammaOS. Nano improves performance, but demanding
scenes can still slow down; constant 60 FPS and stock-firmware compatibility are
not guaranteed. AYN Thor, AYANEO Pocket DS and both Retroid Pocket Duo models
retain their existing profiles. RG DS Plus is not a separately validated profile.
Some Cocoon setups can reduce Dual Screen performance. The lower display may
still take a moment to resume.

Updating

AM2R Android — 1.5.5.11 Hotfix 1

AM2R Android — 1.5.5.11 Hotfix 1

Standard Edition

• Fixed touch controls being unable to select Super Missiles with weapon style
  set to Hold. A Weapon Select button appears above Arm when both missile types
  are available. Hold Arm and tap Weapon Select to switch missile types.
• Toggle mode, physical controller controls and the earlier touch-timing
  improvement keep their existing behavior.

Dual Screen Edition

• Retains the final public 1.5.5.11 gameplay, HUD and menu behavior.

Updating
Repatch your original AM2R 1.1 Windows ZIP and install over your existing edition.
Package IDs and signing are unchanged; game saves and settings are retained.
Do not uninstall the game first. Both game packages use version code 1005007;
the Autopatcher uses version code 11. All other 1.5.5.11 features remain included.

Downloads

AM2R Android — 1.5.5.11

AM2R Android — 1.5.5.11

Builds the Standard or Dual Screen ARM64 Android edition from your own original
AM2R 1.1 Windows ZIP. The installed game runs independently of the autopatcher.

Changes since 1.5.5.10 Hotfix 1

• Standard: touch controls are sampled before the gameplay input update, avoiding
  the extra simulation-step delay. Physical-controller handling is preserved.
• Dual Screen: HUD Style offers Large or Minimal for the lower screen. Large
  is the default for new settings; existing choices are preserved. Large uses
  separate health and ammo rows, tall blue energy bars, remaining ammo grouped
  on the left, and the area title on the right. Metroid counters sit above the
  area title with matching panel edges; completion percentage sits at the far
  right of the timer strip. Minimal remains available, and HUD Style is disabled
  when HUD Screen Position is Top Screen.
  One bottom toolbar shows + / - / 1x / Fit Map / Follow during play, and
  Marker / Menu / Unpause on the paused map. All four profile layouts are updated.
• Dual Screen: adds the Mining Facility map title and drill-chamber background.
• Dual Screen: uses the dedicated Dual-Screen controller recommendation
  artwork. Standard keeps its original controller recommendation screen.
• Both games: updated launcher artwork and adaptive icons, clearer application
  names, and Android game-category declarations. Existing package IDs and signing
  compatibility are retained. Game version code increases to 1005006.
• Both games: optional shared-folder save synchronization through Options → Data.
  Checks run before file selection and after saving. Conflicting changes are held
  for review and recovery copies are retained. Configure a separate file-sync
  app to transfer the folder; see SAVE-SYNC.txt. Manual Backup / Restore remains.
• Autopatcher: Android installation results are shown directly. Failed installs
  create a local diagnostic file labeled "share this to github issues page",
  with a Share action. Nothing is uploaded automatically. Cancellation is reported
  separately, and the generated APK remains available in Downloads.
• Autopatcher: native patch-library alignment and APK compatibility diagnostics
  improve support and troubleshooting on newer Android devices.
• Source: shared game metadata and independent artwork-export helpers are included.
  Cocoon supports manual title/artwork editing; automatic custom-metadata import
  has not been confirmed. Artwork payloads remain outside the code-only archives.

Updates and compatibility
Install over the existing edition to retain its private saves. Do not uninstall
first. Standard and Dual Screen remain separate apps with separate save storage;
use the existing Data backup/restore tools to transfer progress.

AYN Thor has physical test coverage. RG DS, Retroid Pocket Duo / Duo Lite and
AYANEO Pocket DS profiles still await physical validation. The pinned game runtime
has a remaining native 16 KB alignment limitation, so installation on every
16 KB-page device is not guaranteed. Include the new installer report when an
installation fails. Syncthing transfers passed between two isolated Android
emulators and a Linux PC, including conflict handling. Desktop import/export
remains manual. Physical-device sync, Windows/macOS and other services still
need feedback; no network service is built into the game.

AM2R Android — 1.5.5.10 Hotfix 1

AM2R Android — 1.5.5.10 Hotfix 1

This hotfix updates the Dual Screen edition:

• Restores the reactor core temperature bar exclusively on the upper screen.
• Restores screen's 60 fps for smoother map panning, log scrolling and menus.
• Adds Display Options → HUD Screen Position. Keep health and ammunition
  below, or move them to the original upper HUD. The map, timer, completion
  percentage and Metroid counts remain below. The choice is saved.
• Restores upper-screen area-arrival titles and preserves the HUD while paused.

To update, install the new autopatcher, choose Dual Screen, patch your original
AM2R 1.1 Windows ZIP again, then install the generated APK over your existing
game. Back up first; do not uninstall the game. Updating the autopatcher alone
does not update an installed game. Standard users do not need to repatch.

The release includes the autopatcher APK, three code-only source ZIPs and
SHA256SUMS. Source media and signing files are excluded; original code licenses
and attribution are retained. No complete game APK is distributed.

AM2R Android — 1.5.5.10

AM2R Android — 1.5.5.10

An update to 1.5.5.9, with new area backdrops and display fixes. The autopatcher
turns your own copy of the original AM2R 1.1 Windows release (AM2R_11.zip)
into either the Standard or Dual Screen Android edition. Nothing playable is
hosted here.

AYN Thor has been tested on physical hardware and confirmed working.
RG DS, Retroid Pocket Duo / Duo Lite and AYANEO Pocket DS profiles are included,
but physical compatibility remains unconfirmed. Desktop display tests do
not establish performance on those handhelds.

Changelog since 1.5.5.9

Dual Screen [CONTAINS SPOILERS]

• Added the standard menu sounds to first-boot hardware selection, for changing
  the highlighted profile and confirming by controller or touch.

• Replaced the temporary log-picture map backgrounds with 28 selected room
  views, treated with a green palette to match the map. Different subareas
  have their own backgrounds, including the intact egg in the laboratory.

• Added changing backgrounds for the activated tower and the Power Plant
  before and after the escape. Area headings follow the current background,
  with transitions between them.

• Reframed the inner Tower using the room before Plasma Beam, with matching
  dark and powered views. The Distribution Center interior now uses one
  sawblade-room view, with a separate underwater room view.

• Changed filled energy tanks to yellow (#F2CE45) on the lower HUD. Selected
  weapons use yellow Standard-style artwork with subtle scanlines and rounded
  corners inside the green dividers. The separate selection underline is removed.
  Hold mode turns the selected box white while the weapon button is held.
  Empty tanks remain gray and unselected weapons remain green.

• Added a red pulse to the lower health digits using the original low-energy
  warning thresholds and timing. Corrected HUD recoloring on mobile GPUs.

• Area pictures and headings now wait for the original environment scan.
  Industrial Complex stays undiscovered until its scan trigger beyond the tall
  wall. Saved discoveries are reused on return visits, and a completed scan
  updates the map without requiring another room transition.

• Fixed a brief GFS Thoth picture and heading appearing when starting or loading
  a save. The lower map now starts with the selected save's current area.

• Kept the title-screen version label inside the RG DS profile's centered 4:3
  picture when it is used on a wider display.

• Cached translated lower-map headings to avoid repeated language-file reads
  while drawing. Captions refresh when the selected language changes.

• Kept the lower map visible during normal room transitions, without the
  previous blackout. The area's picture and heading can change while it remains
  visible.

• Matched the reactor escape's white flash across both screens. This also
  applies when the escape timer expires; the lower display clears for Game Over.
  The successful escape retains the original drain to 05 energy.

• Preserved the selected 8-bit palette when pausing. With a palette enabled,
  the upper screen fades to 70% dimming; with the shader off, it fades to Olive
  with 50% dimming. Pausing no longer briefly reveals the unfiltered picture.

• Set IGT Display to Enabled and made it read-only in Dual Screen Extras,
  matching the timer that is always present on the lower display.

Both game editions

• Restored the left Chozo statue's raised arm in the Golden Temple's three-switch
  item room and mirrored that statue. This changes the decorative tiles;
  room collisions, pickups and puzzle behavior are unchanged.

Autopatcher and source

• Rebuilt both edition payloads with these changes.
• Raised the autopatcher version to 1.5.5.10 and its internal build number to 8.
  Both generated games report version 1.5.5.10 and retain their existing package
  names, signing certificate and game version code.
• Refreshed the separate code-only archives for Standard, Dual Screen and the
  autopatcher, including build notes, license notices and excluded-input manifests.

Updating

1. Install AM2R-Autopatcher-1.5.5.10.apk on ARM64 Android 10 or newer.
2. Choose Standard or Dual Screen and patch your original AM2R_11.zip again.
3. Install the newly generated game APK over the same edition. Back up first;
   updating preserves saves, while uninstalling the game deletes its private saves.

Updating the autopatcher alone does not update an already installed game.
Once installed, the game launches independently of the autopatcher.
Standard and Dual Screen use separate save storage. Use Options → Data →
Backup / Restore to transfer progress between editions or PC Community Updates
1.5.5. Compatibility with original 1.1 or other mods' saves is not implied.

• AM2R-1.5.5.10-dual-source.zip
• SHA256SUMS

Keep these five files together and run sha256sum -c SHA256SUMS to verify them.
The three source archives contain editable code and build/resource definitions.
Images, audio, font payloads, datafiles, compiled binaries, generated patch
payloads, signing material and revision history are excluded from the sources.
The Android autopatcher APK contains the patch data needed to patch your ZIP.

Game code retains the AM2R Community Updates license and original attribution;
autopatcher code retains its MIT notice and xdelta3 its Apache 2.0 notice. The
palette implementation includes its MIT notice. These are code-only exports,
not complete projects that build without additional local inputs. Each README
explains restoration and the pinned build environment. A game rebuild from only
the original Windows 1.1 ZIP is not verified.

Verification and remaining coverage

The generated game APKs retain their release signatures and are checked against
their signed build checksums. Both edition payloads are reconstructed from the
original ZIP and compared byte-for-byte with those builds.

Focused checks cover normal room crossings, selected palettes while pausing,
the IGT setting, both reactor outcomes and the statue room. The new HUD colors
were checked across all four profiles, including health changes and weapon
selection; the new room pictures were checked with the original scan gates.
New and continued saves were checked across all four profiles, including returning
from GFS Thoth to a new save. The title label was checked in widescreen and at
640x480. Cached headings were compared with the original text and drawing across
all 13 bundled languages, including language changes and area-name fades.
These do not amount to a new full-game playthrough. AYN Thor is the physically confirmed Dual Screen
device; the other profiles still need testing on their actual handhelds.
This release does not guarantee 60 fps on every device. Please include the device,
Android version, selected profile and reproduction steps with issue reports.
