# Unlucky Launcher {{VERSION}}
|
|
|
|
Rust-native **single-file** Minecraft launcher: Slint + Metro UI, built-in AI agent
|
|
(chat / config edits / crash diagnosis) and an MCP server other agent tools can attach to.
|
|
No WebView, no bundled runtime, no JRE download needed to start the launcher itself.
|
|
|
|
## Downloads
|
|
|
|
| Platform | Asset | Notes |
|
|
| --- | --- | --- |
|
|
| Windows 10/11 x64 | `unlucky-launcher-{{VERSION}}-windows-x64.exe` | single exe, double-click to run |
|
|
| Linux x64 (X11/Wayland) | `unlucky-launcher-{{VERSION}}-linux-x64.tar.gz` | single binary inside, no installer |
|
|
| macOS 12+ Apple Silicon | `unlucky-launcher-{{VERSION}}-macos-arm64.tar.gz` | single binary inside, no installer |
|
|
| macOS 12+ Intel | `unlucky-launcher-{{VERSION}}-macos-x64.tar.gz` | single binary inside, no installer |
|
|
|
|
`LICENSE`, `NOTICE` and `README.md` ship in every archive; on Windows they are attached to
|
|
this release next to the `.exe` (a lone exe cannot carry them), so the license terms travel
|
|
with the download on every platform.
|
|
|
|
## Support matrix
|
|
|
|
| Platform | Level | Runtime requirements |
|
|
| --- | --- | --- |
|
|
| Windows 10/11 x64 | first class | nothing beyond the OS (UCRT is part of Win10+) |
|
|
| macOS 12+ (arm64 / x64) | first class | nothing; unsigned build, see Gatekeeper note |
|
|
| Linux x64, X11 | first class | `libxkbcommon`, `fontconfig`, `libGL` (or software renderer), `libxcb` |
|
|
| Linux x64, Wayland | supported | `wayland-client`, `libxkbcommon`, plus the X11 set for XWayland apps |
|
|
| Windows 8.1/8/7 | unsupported | baseline was raised to Win10 (decision D21) |
|
|
| Android — Termux + X11 | experimental, not promised | CLI only (build from source), GUI unverified; not part of this release matrix |
|
|
|
|
## Install
|
|
|
|
**Windows** — put the `.exe` anywhere and run it. Portable data lives next to the exe when a
|
|
`portable.marker` file is present, otherwise under `%APPDATA%`.
|
|
|
|
**Linux**
|
|
|
|
```bash
|
|
tar -xzf unlucky-launcher-{{VERSION}}-linux-x64.tar.gz
|
|
cd unlucky-launcher-{{VERSION}}-linux-x64
|
|
chmod +x unlucky-launcher && ./unlucky-launcher
|
|
```
|
|
|
|
**macOS**
|
|
|
|
```bash
|
|
tar -xzf unlucky-launcher-{{VERSION}}-macos-arm64.tar.gz
|
|
cd unlucky-launcher-{{VERSION}}-macos-arm64
|
|
xattr -d com.apple.quarantine unlucky-launcher # unsigned build, Gatekeeper quarantine
|
|
chmod +x unlucky-launcher && ./unlucky-launcher
|
|
```
|
|
|
|
## No GPU? Software renderer
|
|
|
|
The UI prefers OpenGL (femtovg) and falls back to Slint's CPU renderer when no usable GL
|
|
driver is present. Force it on any machine with:
|
|
|
|
```bash
|
|
unlucky-launcher --software-renderer # or: SLINT_BACKEND=winit-software unlucky-launcher
|
|
```
|
|
|
|
## Verify the download
|
|
|
|
```bash
|
|
# Linux / macOS
|
|
sha256sum -c SHA256SUMS.txt --ignore-missing
|
|
# Windows (PowerShell)
|
|
Get-FileHash .\unlucky-launcher-{{VERSION}}-windows-x64.exe -Algorithm SHA256
|
|
```
|
|

|
## Known limitations of this build
|
|
|
|
- Microsoft (MSA) account login depends on a Mojang app-id whitelist that is still pending;
|
|
until it is granted, use offline accounts or authlib-injector (the 403 is reported with a
|
|
readable diagnostic instead of a silent failure).
|
|
- Binaries are not code-signed / notarized yet: Windows SmartScreen and macOS Gatekeeper warn
|
|
on first launch. Checksums above are the integrity reference for now.
|
|
- macOS ships the bare binary (single-file promise), not a `.app` bundle: no Dock icon or
|
|
Finder double-click — launch it from a terminal.
