The Wheefun Emulator Framework (WFEF) aims to provide low-level hardware emulation primitives for writing new emulators, as well as relatively basic implementations for common system architectures (such as the IBM compatible PC). It was originally designed to support the WDMF project, which has need for hardware emulation on modern operating systems.
