Builder v0.1.3

This release updates SCOS Builder with timezone configuration support and the new SCOS Builder application icon.

What this Builder includes

• SCOS Standard ISO building support
• Automatic download of the official SCOS Build Package from GitHub
• Windows ISO selection
• Output folder selection
• SCOS Standard edition marker support
• Lockdown marker support
• Timezone selection support
• SCOS_TIMEZONE.txt marker generation
• SCOS Builder application/window icon

What’s new in v0.1.3

• Added timezone selection before building a SCOS ISO.
• Builder now writes SCOS_TIMEZONE.txt when a timezone is selected.
• Added the SCOS Builder app icon.
• Updated Builder version metadata to v0.1.3.

Timezone marker support

When a timezone is selected, SCOS Builder writes:

sources\$OEM$\$$\Setup\Scripts\SCOS_TIMEZONE.txt

Example content:

Eastern Standard Time

During SCOS Standard setup, SCOS Build Package v0.3.6.5 or newer reads this marker and applies the selected Windows timezone.

If Use Windows default is selected, Builder does not create SCOS_TIMEZONE.txt.

Compatibility

Recommended for:

• SCOS Build Package v0.3.6.5 or newer
• SCOS Standard public beta builds using timezone configuration

Older SCOS Build Packages may still build, but they may not use the new timezone marker feature.

Notes

• Users still need to provide their own official Windows ISO.
• SCOS Builder does not provide, modify, or activate Windows licensing.
• oscdimg.exe is still required to create the final bootable ISO.
• Bluetooth controller setup is not supported in SCOS Standard at this time.
• SCOS Standard currently focuses on USB and dedicated wireless receiver controller support.

Third-party software

Windows, Steam, EA App, Unified Remote, Microsoft .NET, Windows ADK, and other third-party software remain owned by their respective companies.
