ArkOS4Clone-20260808

Emergency Update Notes – 2026-08-07

Critical fix: This update addresses the N64 boot failure introduced in the 2026-08-05 release.

What's New
Updated ScummVM to 2026.3.0 [2026-08-07]

Fixed N64 emulator startup failure – games no longer crash back to the game selection menu

If You Prefer Not to Update
You can manually apply the N64 fix by following the instructions in this issue:

🔗 #446 – N64 emulators fail to boot

⚠️ Important: Black Screen After Boot (Logo Shows Then Goes Black)
If your device (under GameConsole) displays the logo and then goes to a black screen:

Press and hold the power button for 20 seconds until the power LED turns off completely.

Connect the charger and power on the device.

Cause: This happens when the battery level is too low to maintain the power supply. The device will not boot normally until it has received sufficient charge.

dArkOS4Clone-20260625

dArkOS4Clone (2026-06-24)

Feature-Synchronized ArkOS4Clone-20260624 Release

Status:
The dArkOS4Clone (Beta) build has undergone testing and no critical issues have been identified at this time.

Issue Reporting:
To maintain a clear and manageable issue tracker for ArkOS4Clone, please direct all bug reports and feedback to the dedicated thread:
#387
We will monitor this channel and respond accordingly.

OTA Updates:
An OTA upgrade package is not available for this release. Given that dArkOS remains under active development, providing OTA support at this stage would introduce significant maintenance overhead. We are currently evaluating the best approach for future updates and will provide more information once a viable solution is determined.

ArkOS4Clone-20260624

Fix the missing ES Wi-Fi detection service.
Add support for persistent ZRAM configuration.
Add support for the R36UltraX device.
In this update, the firstboot.sh file must be replaced in order to complete the update.

ArkOS4Clone-20260621

ArkOS4Clone - 20260621

1. Fixed black screen issue in PPSSPP for certain games
2. Fixed the bug where 351Files could not be opened
3. Added Flycast 2022 standalone emulator
4. Fixed the issue where the device required a charger connection when the battery voltage dropped below 3.5V in the powered-off state (the previous fix didn't seem to take effect, and I'm not entirely sure if this one will either)
5. Fixed the bug where some devices would automatically power on when charging while powered off (if you still encounter the auto-power-on issue when charging in the off state, please file an issue report)
6. Added network proxy support for the ES (EmulationStation) interface
7. Added bilingual (Chinese/English) support for both the Flycast standalone emulator and the Flycast 2022 standalone emulator. The interface now automatically switches between Chinese and English based on the ES language setting.
8. Fix drastic-kk. The previous version's dependency copying all failed with || true, which is a nightmare.

dArkOS4Clone- (Beta)

Release Note – dArkOS4Clone (Beta)

Release Date: June 21, 2026

About This Release

dArkOS4Clone is an early-stage version intended for contributor testing only. The goal is to explore and validate new possibilities while maintaining the core experience of dArkOS.

Important Notes & Feedback Guidelines

This release is not designed for general daily use.

• Testing Scope: We invite willing contributors to participate in testing. The primary focus is to identify regression issues — that is, problems where dArkOS runs fine, but dArkOS4Clone exhibits unexpected behavior that was not present in the original dArkOS.

• Feedback Channel: If you encounter any such regressions, please report them here:
  #387

• Important Reminders:

  • Do NOT report compatibility issues such as failure to boot or getting stuck on the logo screen through this channel.
  • Regular users should continue using the stable and reliable ArkOS4Clone release.
