1. Privacy policy in Settings

   Added a privacy policy button to iOS and Android Settings. You can also find it with settings search and read it without connecting Drive.

2. Uninstall and support-email retention

   The policy explains backups and connection details that remain after uninstalling or disconnecting Drive. The operator deletes support emails and attachments 90 days after the request is resolved.

3. Android helper-library notices

   Android

   Added the BSD copyright and disclaimer notices for the PPSSPP graphics-driver helper libraries packaged on Android. The PPSSPP notice now also distinguishes how iOS and Android run the core.

4. Verify build versions and provenance

   Validation now fails when a built package differs from the source version. New tools record hashes and signature status for distribution review and package the matching source and submodules together. This does not mean store availability or licence clearance.

1. Swipe back restored on iOS

   iOS

   On iOS, swipe right from the left edge to return from screens such as subpages in Settings. This restores the back gesture that stopped working after the pixel-style top bar was introduced. The gesture is not enabled on top-level screens or during gameplay, and no forward gesture has been added. We still need to check on a real device that swiping from the edge during play does not take you out of the game screen.

1. Saves and settings in one file

   Export every save profile for up to 256 games to a .nemubackup file. Optionally include app/game settings and imported skins and PSP fonts. Review games, profiles and save items before choosing replacements.

2. DS screen layouts on Android

   Android

   Android now offers DS arrangement, ratio, single-screen focus, screen swap and touch calibration. It uses the same stored settings as iOS and maps touch input to the actual bottom screen.

3. Find settings by name and description

   Search app and system-specific settings from Settings. Select a result to open its category and item. Options unavailable in this build stay out of results.

4. A clearer save-data integrity label

   The local save-data check is now named Save Data Integrity Check. Its previous name remains a search alias. Check Drive Data keeps its existing name.

5. More complete SNES and PSP save transfer

   Android per-game save files now carry SNES SRAM and clock data and PSP SAVEDATA. Both clients check save compatibility against cores actually included in the app.

6. Revised iOS haptics for rapid presses

   iOS

   iOS now reuses short haptic patterns to address feedback dropping out during rapid button presses. Physical-device continuity and interaction with game audio still need verification.

7. Fewer allocations when importing states

   Android

   Android reads state files without loading the entire file into a memory array. A host JVM comparison using a 32 MiB file showed fewer allocations; it did not measure phone memory use or frame performance.

Integrated 2026-09-08

1. Manual and automatic saves at a glance

   When paused, see screenshots and times for the selected manual slot and latest autosave together. The manual slot has Save and Load buttons; the autosave has Load. Save slots and history has been renamed Manage Save Slots.

2. A quit button fixed at the bottom

   The quit button stays at the bottom as you scroll the pause screen. It returns you to the library, asking for confirmation if you have made progress since the last save.

Integrated 2026-09-07

1. Text and buttons appear as screens open

   In settings, the library and other screens, text appears character by character as buttons and covers are drawn. The effect ends within 0.6 seconds; interacting reveals everything immediately. Reduced motion disables it. It does not replay on rotation, returning to the app or scrolling lists.

2. A cursor sized to the text

   The cursor keeps blinking after the text appears. It now matches the text size and has room beside it so it does not cover content. Reduced motion also stops the blinking.

Integrated 2026-09-07

1. Undo loading a save state

   Undo load in the pause menu returns you to just before the state was loaded. Only one undo copy is kept, and it disappears when you restart or quit the game.

2. Quick saves in the pause menu

   Save to or load from the selected slot in the pause menu. Open Manage Save Slots to choose a different slot.

3. Start an imported game right away

   After adding or reconnecting one game, start it directly from the results screen.

4. Choose PSP fonts per game

   Choose a PSP font for each game. Games without their own choice follow the app-wide setting. Changes apply after restarting the game.

5. More buttons in the library

   Game cards and list rows now have a More button. Open game management without a long press.

6. Reorder game information

   Game settings and save-data management come first, with detailed technical information moved lower.

7. Settings organized into six groups

   The settings menu now has six groups. Related features, such as storage and backup, are kept together.

8. Import guidance for an empty library

   A short guide explains how to import games, while the long list of file types is collapsed.

9. Shorter, clearer Korean guidance

   Save terminology was made consistent and feature descriptions revised. Menus now use short, plain Korean to explain what actions do.

10. A brief entrance effect for settings

    The first time settings opens after app launch, the title appears character by character and button borders are drawn. Interacting or enabling reduced motion completes it immediately.

1. Open the website from app information

   The website button in app information opens features, usage help and development news.
