About Capivara Emu

English | Português Capivara EMU 🎮⚡ green.svg) **High-Performance Multi-System Retro Emulation Engine for Android.** Built upon a hardened **Galvanic Isolation Architecture** separating the Reactive TypeScript UI from the native C++ rendering pipeline via asynchronous JNI bridges. 📌 Architectural Overview (Galvanic Isolation) Traditional hybrid emulators fail on mobile due to thread contention: DOM events and garbage collection cycles throttle the rendering loop. **Capivara EMU** completely decouples the control plane (UI) from the execution plane (Native Engine). ⚙️ Core Engineering Achievements 1. Reverse-Engineered Sega VMS (Dreamcast VMU) FAT File System Implemented exact Dreamcast Visual Memory System FAT specifications in binary: Allocation tracking with 0xFFFC unallocated marker. Strict 200 user data blocks format at offset 0x1FE00. Atomicity guaranteed via POSIX fsync flush routines to prevent flash corruption on background suspension. 2. Zero-Copy Native Surface Rendering Video output bypasses the Chromium/Capacitor WebView DOM completely. Uses ANativeWindow_fromSurface to stream raw framebuffers directly into Android's SurfaceView via GLES3 hardware textures. 3. Clean EGL Teardown & Cold Reboot Lifecycle Prevents GPU driver context leaks during multi-console switching (e.g. from *NeoGeo MVS* to *PlayStation 2*). Full teardown of EGLDisplay, EGLSurface, and EGLContext…
