Most people want: the build for their platform — Windows → x64 installer · macOS → Apple Silicon or Intel .dmg · Linux → AppImage
Every build is a ⚡ lightning build: breakpoint checks and the traceback buffer are stripped from the MIPS executor hot path for maximum speed, so interactive debugging (GDB stub, monitor breakpoints) is not available in them. Build from source without --features lightning if you need to debug IRIX behaviour.
All builds include CHD support (
libchdman-rs≥ 0.288.8) and are distributed under the BSD 3-Clause license. SeeLICENSEand theLICENSE-libchdman-rs.txtthird-party notice in each archive.

Core (no GUI)
The emulator without the GUI layer: every IRIS-cli-* archive contains iris (the emulator, driven by iris.toml and the serial/monitor consoles) and iris-ci (the control-socket client for snapshots, scripted input, and headless automation) at the archive root, on all platforms and architectures.

Windows: x64 + arm64 (32-bit Windows is not shipped). macOS: requires 10.13 High Sierra or later. Linux packages: deb = Debian/Ubuntu, rpm = Fedora/RHEL/openSUSE, pkg = Arch/Manjaro; built against glibc 2.39 (Ubuntu 24.04). AppImage is self-contained and runs on most distributions. † riscv64 is cross-compiled and shipped as a tarball only (no AppImage/deb/rpm), built against glibc 2.35. All binaries include libchdman-rs and are BSD 3-Clause licensed.
Building other configurations: PCAP bridged networking (--features pcap), the experimental JIT v2 engine (--features jitv2), the v1 MIPS JIT (--features jit), the N64 development board (--features ultra64), and the chd_extract tool are all still in the tree — they are just not part of the release matrix. See README.md.
