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.
