1.0.0-rc.1

• Dual-ABI APK (arm64-v8a, x86_64), no game files or generated code embedded.
• Signed with the project debug certificate, SHA-256 1be501578a55867ac0b1fc488d516d33c07d14cfab2b43a69b8ace81e9cb8233 (same as earlier releases; installs over them).
• Install over the existing app; installed games need no reimport or recompilation.

Assets: APK, corresponding source, SHA-256 sums. No Windows builder.

0.4.0-testing.2

SCDA Android 0.4.0-testing.2

Testing prerelease, not stable. VersionCode 16; source 6e1f5e72b685875b997be173de48379e94e5e59e.

Fixed

Main menu music played too fast and clicked (#4). The game was sometimes told a wrong playback position and then overwrote music that had not been played yet, so short pieces were skipped several times a second. Confirmed by ear on a Poco X6 (Adreno 710, 120 Hz) with a test build of the same fix. The menu video was not the cause: it has no audio track.

Also

The log's audio: start line now names the audio driver and the device's sample rate, channels and block size, to help with future audio reports.

Install

Install over the existing app. Do not uninstall or clear app data: that deletes saves/settings. Existing games need no reimport or recompilation.

0.4.0-testing.1

SCDA Android 0.4.0-testing.1

Testing prerelease, not stable. VersionCode 15; source de0a0a0f1b7079c807b8ad2f549f21916c90dc4e.

New

Faster on Mali GPUs. Devices with an ARM Mali GPU now use a lighter wait between render passes by default. On the test tablet (Huawei AGS3K, Mali-G51, 50% render resolution) one stationary view went from about 20.7 to 24.5 FPS. Other GPUs behave as before.

GPU SYNC option (Recomp Settings > Performance), applied live:

• Automatic (default): relaxed on Mali, strict everywhere else.
• Relaxed (faster): the lighter wait on any GPU.
• Strict: the previous behaviour. Choose this if effects flicker or look broken.

Help for settings. In the game's Recomp Settings and Controller pages, press Y on a row to read what it does. Available in English, French, German, Italian and Spanish. Controller only; there is no keyboard key for it.

Install

Install over the existing app. Do not uninstall or clear app data: that deletes saves/settings. Existing games need no reimport or recompilation.

0.3.0-testing.2

SCDA Android 0.3.0-testing.2

Testing prerelease, not stable. VersionCode 14; source 91451ca.

New

Export error logs (ZIP) in the Android launcher:

• Choose the destination using Android's file picker.
• Includes saved game logs, the last setup error and Vulkan diagnostics when available.
• No game files or saves, no automatic upload. Logs may contain file paths: review before sharing.
• Setup/import errors are now saved for later export. This is not a full Android logcat capture.

Install

Install over the existing app. Do not uninstall or clear app data: that deletes saves/settings. Existing games need no reimport.

Validation

The user exported a ZIP using the preceding test build: all entries passed CRC validation, with 13 game logs, README and Vulkan report. ZIP allowlist/content/missing-storage tests, cache/import/update tests, Python tests and native host tests passed. Production APK built and inspected for both ABIs, version and signature; no embedded game code.

The exact version-bumped APK was not separately device-tested. Picker cancellation/storage failures and setup-error export have not been device-tested.

0.3.0-testing.1

SCDA Android 0.3.0-testing.1

Testing prerelease. VersionCode 13, source 049c761.

New

• Anti-aliasing: Recomp Settings → GRAPHICS → ANTI-ALIASING: OFF / FXAA (fast) / SMAA (default). Smooths the finished frame before upscaling; barely any performance impact on Adreno 710.
• Anisotropic filtering 4x by default.
• Update check at app start: quiet; a notice appears only when a newer release exists.
• Main menu: only Solo, Credits and Exit (no Coop/Versus).

New defaults apply to new or reset settings only; saved choices are kept.

Windows builder retired

No Windows builder is published from this version on. ARM64 and x86_64 compile the game on the device. Game ZIPs from a versioned builder are refused for new imports; import the ISO, archive or game folder instead. Installed games are not affected.

Install

Install over the existing app. Do not uninstall or clear app data (deletes saves/settings). Installed games need no reimport.
