Couldn't load the latest release info just now, so this shows version 0.3.1 from when the page was made. There may be a newer one: try reloading.

macOSNot yet. I have no Mac to test on, and I'd rather ship nothing than something broken.
LinuxNot yet either. The game side would mostly work; the window and installer parts are Windows-only today.
Bedrock resource packNot the launcher: a neon menu, logo and hotbar for Minecraft Bedrock, made to match. Download the .mcpack (1.9 MB). Double-click it with Bedrock installed.
Older versionsListed in the dev log. Use the newest; old ones don't get fixes.

Before you install

What you need

System
Windows 10 or 11, 64-bit. Microsoft Edge WebView2, which both already have.
Account
A Microsoft account that owns Minecraft: Java Edition. There's no offline mode.
Memory
8 GB RAM is comfortable; the game gets 4 to 8 GB of it (you choose in Settings).
Disk
About 200 MB for the launcher and Java, plus 500 MB to 1 GB per Minecraft version you play.
Internet
For sign-in and the first launch of each version. After that, mostly for mod updates.

"Windows protected your PC"?

Windows says it's unrecognized

That blue screen is Windows SmartScreen. It shows for programs that are new and not signed with a paid code-signing certificate. NULLSPARK is both of those right now. It doesn't mean anything was found in the file.

Click More info, then Run anyway. You only see it once per version.

If you'd rather check first, compare the file's fingerprint with the SHA-256 above. In PowerShell, in the folder with the file:

Get-FileHash .\NULLSPARK-Setup-0.3.1.exe

The Hash it prints should match, letter for letter (capitals don't matter). If it doesn't, don't run it; download it again from this page.
