MAME4droid (Current) is a powerful Android port of the MAME 0.288 emulator (by MAMEDev and contributors), developed by David Valdeita (Seleuco). It supports over 40,000 different ROMs and emulates classic arcade systems along with home computers like ZX Spectrum, Amstrad CPC, and MSX.

• No ROMs Included: MAME4droid is strictly an EMULATOR and DOES NOT INCLUDE ROMS or copyrighted material.
• Not Affiliated with MAMEDev: This project is independent of the official MAME team.
• High-End Hardware Recommended: Based on the latest PC MAME version, it requires high specifications. Modern games (90s+) may not run at full speed on all devices.
• Support: Due to the massive library of titles, support for specific individual games cannot be provided.

While MAME is known for being demanding, this version includes modern optimizations for mobile hardware:

• arm64 DRC (Dynamic Recompiler): Recent versions now feature a dedicated 64-bit ARMv8 recompiler (DRC). This provides a massive performance boost for complex systems (like Killer Instinct or CPS-3), allowing them to run much faster than in older, legacy emulators.
• Requirements: Despite these optimizations, a high-end Android device is still recommended for the most demanding 90s-era 3D arcade games to achieve full speed.

For the best experience and to save internal storage, it is recommended to store your ROMs on external storage using Android's Scoped Storage system.

1. Prepare your external storage: Create a folder named MAME4droid (or any name you prefer) on your SD card or internal memory.
2. Initial Launch: Open the app for the first time.
3. Path Selection: When asked "Where do you have stored or want to store your roms files?", select EXTERNAL STORAGE.
4. Grant Permission:
   • The Android file picker will open. Navigate to your external storage, select the folder you created, and tap "Use this folder".
   • Tap Allow to give MAME4droid permission to access that directory.
5. Romset Version: Ensure you are using the '0.288' romset for compatibility.

Note: If you already installed it, you can change the path in Options > Settings > General > Change ROMs path.

• 🎮 Controls: Plug-and-play support for Bluetooth/USB gamepads, touch lightgun, and mouse support.
• 📱 Interface: Autorotation, customizable button layouts (1-6 buttons), and tilt sensor support.
• 🎨 Visuals & Shaders:
  • HDR Rendering: Dedicated FP16 HDR rendering path for vector games, alongside SDR-to-HDR highlight expansion for raster games.
  • Physical CRT Vector Simulation: A fully custom vector rendering engine that accurately replicates the physical and optical properties of classic arcade vector CRT monitors.
  • Shader Support: This version includes advanced shader support for a more authentic retro look.
  • How to Enable: Shaders must be manually activated. Go to Options > Settings > Shaders to select and enable your preferred effects.
  • Filters: Includes overlay filters like scanlines and CRT effects.
