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.

Downloads and source

• AM2R-Autopatcher-1.5.5.10.apk
• AM2R-Autopatcher-1.5.5.10-source.zip
• AM2R-1.5.5.10-standard-source.zip
• AM2R-1.5.5.10-dual-source.zip

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.
