Last Updated: October 4, 2025
This roadmap tracks upcoming releases and major ongoing initiatives.
Current Focus
- Finish overworld editor parity (sprite workflows, performance tuning).
- Resolve dungeon object rendering and tile painting gaps.
- Close out Tile16 palette inconsistencies.
- Harden the
z3ed automation paths before expanding functionality.
0.4.0 (Next Major Release) - SDL3 Modernization & Core Improvements
Status: Planning
Type: Major Breaking Release
Timeline: 6-8 weeks
Primary Goals
- SDL3 migration across graphics, audio, and input
- Dependency reorganization (
src/lib/ + third_party/ → external/)
- Backend abstraction layer for renderer/audio/input
- Editor polish and UX clean-up
Phase 1: Infrastructure (Week 1-2)
- Merge
src/lib/ and third_party/ into external/
- Update CMake, submodules, and CI presets
- Validate builds on Windows, macOS, Linux
Phase 2: SDL3 Core Migration (Week 3-4)
- Switch to SDL3 with GPU-based rendering
- Introduce
GraphicsBackend abstraction
- Restore window creation and baseline editor rendering
- Update the ImGui SDL3 backend
Phase 3: Complete SDL3 Integration (Week 5-6)
- Port editors (Overworld, Dungeon, Graphics, Palette, Screen, Music) to the new backend
- Implement SDL3 audio backend for the emulator
- Implement SDL3 input backend with improved gamepad support
- Benchmark and tune rendering performance
Phase 4: Editor Features & UX (Week 7-8)
- Resolve Tile16 palette inconsistencies
- Complete overworld sprite add/remove/move workflow
- Improve dungeon editor labels and tab management
- Add lazy loading for rooms to cut load times
Phase 5: AI Agent Enhancements (Throughout)
- Vim-style editing in
simple-chat (complete)
- Autocomplete engine with fuzzy matching (complete)
- Harden live LLM integration (Gemini function-calling, prompts)
- Attach AI workflows to GUI regression harness
- Extend tool coverage for dialogue, music, sprite data
Success Criteria
- SDL3 builds pass on Windows, macOS, Linux
- No performance regression versus v0.3.x
- Editors function on the new backend
- Emulator audio/input verified
- Documentation and migration guide updated
Breaking Changes:
- SDL2 → SDL3 (requires recompilation)
- Directory restructure (requires submodule re-init)
- API changes in graphics backend (for extensions)
0.5.X - Feature Expansion
- Plugin Architecture: Design and implement the initial framework for community-developed extensions and custom tools.
- Advanced Graphics Editing: Implement functionality to edit and re-import full graphics sheets.
- **
z3ed AI Agent Enhancements**:
- Collaborative Sessions: Enhance the network collaboration mode with shared AI proposals and ROM synchronization.
- Multi-modal Input: Integrate screenshot capabilities to send visual context to Gemini for more accurate, context-aware commands.
0.6.X - Content & Integration
- Advanced Content Editors:
- Implement a user interface for the music editing system.
- Enhance the Hex Editor with better search and data interpretation features.
- Documentation Overhaul:
- Implement a system to auto-generate C++ API documentation from Doxygen comments.
- Write a comprehensive user guide for ROM hackers, covering all major editor workflows.
Recently Completed (v0.3.3 - October 6, 2025)
- Vim mode for
simple-chat: modal editing, navigation, history, autocomplete
- Autocomplete engine with fuzzy matching and FTXUI dropdown
- TUI enhancements: integrated autocomplete UI components and CMake wiring
Recently Completed (v0.3.2)
- Dungeon editor: migrated to
TestRomManager, resolved crash backlog
- Windows build: fixed stack overflows and file dialog regressions
z3ed learn: added persistent storage for AI preferences and ROM metadata
- Gemini integration: switched to native function calling API
- Tile16 editor: refactored layout, added dynamic zoom controls
