Cogwheel 1.0.3.0 beta 3

Cogwheel 1.0.3.0 beta 3 is released.Cogwheel ia a software emulator primarily for 8-bit Sega hardware, such as the Sega Master System, Sega Game Gear and SG-1000. The ColecoVision is also supported.The project uses a modular design based around a Z80 core emulator class library. The rest of the Sega-specific emulation is implemented in another class library, and the user interface is implemented as a separate application. This would allow the main emulator to be easily adapted to different interfaces.The code is written in C# 3.0 (targetting .NET 2.0). The user interface uses Windows Forms, with SlimDX being used to render the graphical output to the form as quickly as possible.
