Simbuino v 1.0.0.19 - Gamebuino Emulator. Copyright (c) 2014-2015 Mark Feldman (aka "Myndale" on the Gamebuino forums).

Application Overview
====================
Simbuino is an open-source Windows-based emulator for the Gamebuino hand-held console (see http://gamebuino.com). The latest version of the code and binaries are
available from the following GitHub repository:

Source Code Overview
====================
Simbuino is a C#/WPF (.NET 4.5) Windows application developed for Microsoft Visual Studio Express 2013. In general the code attempts to adhere strictly to the MVVM
architectural pattern, although there are currently some minor violations that require clean up. The solution is divided into the following project workspaces:

	- Simbuino: Application entry point only, contains no logic itself other than to store the application class and bind the other workspaces.
	- Simbuino.UI: Responsible for all user interface code. Contains both views and view models for the sake of convenience, although these are kept
      architecturally separate.
	- Simbuino.Emulator: Contains main Gamebuino emulation code i.e. micro-controller and peripherals.
	- Simbuino.Hardware: Small project that handles communication with Gamebuino hardware (i.e. game uploads).
	- MvvmDialogs: Generic library used to add dialog box functionality to MVVM applications.

The SIMULATION.TXT file contains details as to how the simulation code works. In addition to the usual DEBUG and RELEASE project configurations there is one called
PROFILE which currently runs very slow but can be used to measure the execution time of the individual op-code handlers.

Simbuino4Web
==============
The Simbuino\src\Simbuino4Web folder contains an experimental HTML5 port of the core Simbuino engine developed for Microsoft Visual Studio Express 2012 for Web. A
runtime version of this project is currently hosted at http://simbuino4web.ppl-pilot.com. It is recommended that you run this version of Simbuino under either Chome
or Firefox; it will work with Internet Explorer but runs very slowly and without sound.

3rd-Party Code
==============
Simbuino uses the following 3rd-party libraries and code:

	- MVVM Lite (https://mvvmlight.codeplex.com). Tool-kit for developing MVVM applications in WPF.
	- Extended WPF Toolkit (http://wpftoolkit.codeplex.com/). Collection of controls, components and utilities for creating WPF applications.
	- HiPerfTimer (Daniel Strigl, http://www.codeproject.com/Articles/2635/High-Performance-Timer-in-C). High performance timer used to profile code.
	- MvvmDialogs (Mark Feldman, http://www.codeproject.com/Articles/820324/Implementing-Dialog-Boxes-in-MVVM). Library for displaying dialog boxes in MVVM applications.
	- AvalonDock (https://avalondock.codeplex.com). Docking Windows library for WPF.
	- Animated GIF Encoder (Kevin Weiner/FM Software, http://www.fmsware.com/stuff/gif.html). 
	- SharpDX (http://sharpdx.org). Managed DirectX API used by the sound engine.
