A cross-platform Zelda 3 ROM editor with a modern C++ GUI, Asar 65816 assembler integration, and an automation-friendly CLI (z3ed). YAZE bundles its toolchain, offers AI-assisted editing flows, and targets reproducible builds on Windows, macOS, and Linux. A preview web version is also available for browser-based editing.
- All-in-one editing: Overworld, dungeon, sprite, palette, and messaging tools with live previews.
- Assembler-first workflow: Built-in Asar integration, symbol extraction, and patch validation.
- Automation & AI:
z3edexposes CLI/TUI automation, proposal workflows, and optional AI agents. - Web preview: Experimental browser-based editor (WASM) - see Web App Guide.
- Testing & CI hooks: CMake presets, ROM-less test fixtures, and gRPC-based GUI automation support.
- Cross-platform toolchains: Single source tree targeting MSVC, Clang, and GCC with identical presets.
- Modular AI stack: Toggle agent UI (
YAZE_BUILD_AGENT_UI), remote automation/gRPC (YAZE_ENABLE_REMOTE_AUTOMATION), and AI runtimes (YAZE_ENABLE_AI_RUNTIME) per preset.
0.3.x builds are in active development. Release automation is being reworked, so packaged builds may lag behind main. Follow develop for the most accurate view of current functionality.
git clone --recursive https://github.com/scawful/yaze.git
cd yazeRun the environment verifier once per machine:
# macOS / Linux
./scripts/verify-build-environment.sh --fix
# Windows (PowerShell)
.\scripts\verify-build-environment.ps1 -FixIssues- Use the CMake preset that matches your platform (
mac-dbg,lin-dbg,win-dbg, etc.). - Build with
cmake --build --preset <name> [--target …]. - See
docs/public/build/quick-reference.mdfor the canonical list of presets, AI build policy, and testing commands.
| Option | Default | Effect |
|---|---|---|
YAZE_BUILD_AGENT_UI |
ON when GUI builds are enabled |
Compiles the chat/dialog widgets so the editor can host agent sessions. Turn this OFF when you want a lean GUI-only build. |
YAZE_ENABLE_REMOTE_AUTOMATION |
ON for *-ai presets |
Builds the gRPC servers/clients and protobufs that power GUI automation. |
YAZE_ENABLE_AI_RUNTIME |
ON for *-ai presets |
Enables Gemini/Ollama transports, proposal planning, and advanced routing logic. |
YAZE_ENABLE_AGENT_CLI |
ON when CLI builds are enabled |
Compiles the conversational agent stack consumed by z3ed. Disable to skip the CLI entirely. |
Windows win-* presets keep every switch OFF by default (win-dbg, win-rel, ci-windows) so MSVC builds stay fast. Use win-ai, win-vs-ai, or the new ci-windows-ai preset whenever you need remote automation or AI runtime features.
All bundled third-party code (SDL, ImGui, ImGui Test Engine, Asar, nlohmann/json, cpp-httplib, nativefiledialog-extended) now lives under ext/ for easier vendoring and cleaner include paths.
./build/bin/yaze– full GUI editor with multi-session dockspace, theming, and ROM patching.- Web App (Preview) – browser-based editor at your deployed instance; see
docs/public/usage/web-app.mdfor details and limitations. ./build/bin/z3ed --tui– CLI/TUI companion for scripting, AI-assisted edits, and Asar workflows../build_ai/bin/yaze_test --unit|--integration|--e2e– structured test runner for quick regression checks.z3ed+ macOS automation – pair the CLI with sketchybar/yabai/skhd or Emacs/Spacemacs to drive ROM workflows without opening the GUI.
Typical commands:
# Launch GUI with a ROM

# Apply a patch via CLI
./build/bin/z3ed asar patch.asm --rom zelda3.sfc
# Run focused tests
