Easier first-time setup
Windows and Linux setup now automatically downloads a prepared build-tool archive in Step 1. You do not need to install MSYS2 or a compiler yourself. Downloads are verified against the release's SHA-256 checksum before installation.
Tools live in the launcher's private data folder and are reused across launcher updates. Failed tool replacements restore the previous installation. Saves and backups remain separate from these tools and from game builds.
Choose the usual launcher download for your operating system. The tool archives are separate release assets; the launcher downloads its required archive automatically. Corresponding source and license files are available in the linked toolset release.
Both Linux and Windows archives are checked by compiling a fresh port using the extracted tools. This test is independent of packaging the Electron app.
macOS continues to use Apple's development tools. Linux and Windows tool setup supports 64-bit Intel/AMD computers; the current Windows port build target remains 32-bit.
Bring your own supported disc image. No ROM, extracted game assets, or compiled game binary is included.
