Fixed in commit 83b5795. Added coherent CSS animations with cubic-bezier easing, staggered card appearances, pulse effects on focused elements, and improved text alignment with proper line-height properties. All transitions are GPU-accelerated for smooth 60 FPS performance.
Added in commit 30d578b. Implemented experimental EmulatorJS integration with:
Games launch from Library in Big Picture mode when platform is supported. Press Enter/A to play, ESC to exit. |

Pull request overview
This PR implements a comprehensive Big Picture Mode for Jacare, providing a Steam-style 10-foot UI optimized for TV and controller usage. The implementation includes experimental EmulatorJS integration for in-browser game playing, comprehensive E2E test coverage with Playwright, and smooth animations for a polished user experience. The PR also includes a successful Vitest v4 migration using the new projects configuration pattern.
Key Changes
- Big Picture Mode UI: Full-screen, controller-friendly interface with large typography, focus indicators, and gamepad navigation support via the Gamepad API
- EmulatorJS Integration: Experimental web-based emulator support for multiple retro platforms (NES, SNES, GBA, N64, PS1, etc.) with graceful error handling
- E2E Test Suite: Three comprehensive test scenarios covering navigation, interaction, and focus states using Playwright with properly scoped selectors

The BigPicturePage component is wrapped in a BrowserRouter when bigPictureMode is true, but BigPicturePage uses router hooks (useNavigate, useLocation) which expect to be within a router context. This creates a nested router structure where the BigPicturePage route is never actually matched, since it's not within the Routes definition. The component will work for navigation but bypasses the routing system.
Consider either:
- Conditionally rendering BigPicturePage inside the existing router structure, or
- Using navigate programmatically to redirect to /big-picture instead of conditionally rendering

The useEffect that initializes EmulatorJS has an incomplete dependency array. The effect depends on config.biosUrl, config.saveStateUrl, config.gameName, config.romUrl, and config.core, but only includes config and onError in the dependency array. If individual properties of config change without the object reference changing, the emulator won't reinitialize. Consider either adding these specific properties to the dependency array or ensuring config is always a new object when any property changes.

Big Picture Mode Implementation - MVP Complete ✅
Summary
This PR implements a Steam-style Big Picture Mode for Jacare, providing a controller-friendly, fullscreen 10-foot UI optimized for TV/living room usage. The implementation follows the MVP approach with core features working and additional features planned for future iterations.

✅ Completed Features
Phase 1: Core Infrastructure
Phase 2: UI Components
Phase 3: Electron Integration
Phase 4: Testing & Code Quality
🎮 Experimental: EmulatorJS Integration
New Feature: Games can now be launched directly from Big Picture mode using EmulatorJS (experimental).
How It Works:
Supported Platforms:
Documentation: See
docs/EMULATORJS.mdfor installation and configuration guide.Note: This is an experimental feature requiring separate EmulatorJS setup. The integration provides fallback to detail view if EmulatorJS is not installed.
🚧 Future Enhancements
The following features are planned but not included in this MVP:
