Current Version Support: Updated to stay in sync with the latest version of Ample (macOS) resources and also MAME latest binary.

🍎 Ample (macOS) vs. AmpleWin (Windows) Comparison

Feature	Ample (macOS Native)	AmpleWin (Windows Optimized)	Optimization & Notes
Language	Objective-C (Cocoa)	Python 3.11 + PySide6 (Qt)	Independent development, zero changes to Mac source code
Installation	.dmg Image / Homebrew	Portable (+ .bat Auto-Config)	One-click setup for Python and dependencies via AmpleWin.bat
UI	Native macOS Components	1:1 Pixel-Perfect QSS Replica	Replicates Mac aesthetic, with Adaptive Light/Dark Theme support
MAME Integration	Built-in Custom Core or Self-selected	Official Core Download or Self-selected	Users can update MAME independently or download via app
Machine Selection	Supports Default Bookmark	Full Session Persistence (Auto-Load)	Auto-loads last used machine state without manual bookmarking
Software List Perf	Synchronous Loading (Full XML)	Deferred Loading	Major Optimization: Instant machine switching, loads on search
Software Search UI	Standard Pop-up List	Smart Overlay Search	Supports real-time search and full descriptive names without UI shifts
ROM Download	Supports Auto-Download	High-Speed Failover Engine	Major Optimization: Multi-server failover (callapple + mdk.cab)
Validation	Relies on Static .plist	Live Parameter Validation	Major Optimization: Validates against MAME to prevent launch crashes
Video Support	Metal / OpenGL / BGFX	BGFX / OpenGL / Vulkan / D3D11 / D3D12	Optimized for Windows with multi-generational DirectX support
Networking	Apple VMNet Framework	Npcap (WinPcap) / PCAP	Standard networking via Npcap (no root fix needed)
Operating Logic	Sticky Software Selection	Sticky Software Selection	Preserves compatible software selection when switching machines

🌟 Key Features

🍏 Faithful Mac Experience (Feature Parity)

• Visual Precision:
  • Resolution Scaling: Precision support for Window 1x-4x modes with machine-specific aspect ratio heuristics (e.g., Apple II 4:3 correction).
  • Square Pixels: Specialized integer-scaling mode (e.g., 1120x768) to eliminate pixel shimmering.
• Software Library:
  • Smart Filtering: Automatically identifies supported media types (flop1, flop2, cass...) to match machine capabilities.
  • Search Overlay: Integrated Mac-style search with auto-completion and full descriptive names.
  • Compatibility Check: Options marked as disabled in property lists (e.g. incompatible SCSI cards) are now correctly grayed out and unselectable, matching Mac behavior.
• Advanced Slot Emulation: Full support for nested sub-slots (e.g. SCSI cards).
  • Automated Defaults: Automatically initializes default devices (CD-ROM/Hard Disk) upon card selection.
  • Slot Consistency: Improved logic to respect "None" (empty) selections across UI refreshes, matching the high standards of the native macOS port.
• ROM Management:
  • Search Filter: Real-time searching in the ROM manager window to quickly find system firmwares.
  • Download Failover: Automatic multi-server acquisition (callapple + mdk.cab) with transparent failover for maximum stability.
  • Extended Library: Expanded support for PowerBook Duo 280, Pravetz 8C, TK3000, and more.
  • Compatibility Fallback: Automatically detects affected Macintosh PowerBook models (macpb160 etc.) that suffer from the MAME 0.288 EASC crash bug. Seamlessly switches to a local MAME 0.287 (mame_0287.exe) or VGM Mod (mame-vgm.exe), or offers to download the v0.280 fallback copy.
• Shared Directory: Full parity with the Mac version, allowing direct host-to-emulator file sharing via the -share_directory argument. (Includes click-to-browse support).
• VGM Support (Advanced): Since modern MAME removed VGM support, AmpleWin implements a robust background workflow to download and configure the MAME-VGM Mod (v0.280). It uses a non-destructive extraction process (mame-vgm.exe) to preserve your main MAME core while restoring high-fidelity music recording.

🪟 Windows-Specific Optimizations

• Performance:
  • Concurrent Downloading: Multi-threaded system for high-speed ROM acquisition.
  • Clean Workspace: All MAME side-car files (nvram, cfg, sta) are strictly isolated within the mame directory.
  • Deferred XML Loading: Major optimization for instant machine switching and search response.
• UI Enhancements:
  • Adaptive Theme: Real-time synchronization with Windows Light/Dark system theme.
  • Command Preview: Real-time 4-line console preview to monitor exactly what parameters are being passed to MAME.
  • Smart Path Handling: Native file/folder selectors for A/V output and Shared Directories, with automatic path normalization (converting / to \) for maximum Windows compatibility.
• Flexible Backend: Full support for BGFX, OpenGL, Vulkan, and DirectX 11/12 out of the box.

🛠️ Quick Start

1. Launch Ample: Enter the AmpleWin folder and run AmpleWin.bat.
   • The script will check the Python environment, install dependencies, and start the app.
2. Fast Deployment:
   • Go to ⚙️ Settings -> Click Download MAME to auto-configure the emulator.
   • Click 🎮 ROMs to download system firmware.
   • Click 📂 Ample Dir to quickly open the local application folder.
3. Start playing:
   • Select a machine from the left panel.
   • Double-click the machine name or click Launch MAME to start.

🌐 Networking (Advanced)

To simulate networking hardware like Uthernet II, Windows requires Npcap (install in "WinPcap compatible mode"). Unlike the macOS version, no "Fix Permissions" is required as Windows handles hardware access via drivers.

📂 Project Structure

File/Directory	Description
AmpleWin.bat	Start Here. Auto-setup script (installs Python deps & runs app).
build_exe.bat	Packaging. Creates a dist portable EXE folder using PyInstaller.
main.py	Application entry point, UI rendering, and event loop.
data_manager.py	Parser for .plist machine definitions and MAME .xml software lists.
mame_launcher.py	Command-line builder and process manager.
rom_manager.py	Management and multi-threaded downloading of system ROMs.
mame_downloader.py	Automated MAME / VGM Mod downloader and extractor.
mame/	Isolated directory for MAME executable, ROMs, and config files.
Agent.md	Development log and session history.

📦 Building from Source (Portable EXE)

If you want to create a standalone executable for distribution:

1. Run build_exe.bat in the AmpleWin directory.
2. The script will automatically install PyInstaller, package the application, and copy necessary resources.
3. The output will be in AmpleWin\dist\AmpleWin.
4. Copy the entire AmpleWin folder to any location. It is fully portable and does not require Python to run.
