Generator is an open source emulator designed to emulate the Sega Genesis / Mega Drive console, a popular games machine produced in the early 1990s. It is a portable program written in C and has been ported to the Amiga, Macintosh, Windows and even pocket PCs such as the iPAQ and Cassiopeia. Natively it compiles under unix for X Windows with either tcl/tk or gtk/SDL, for svgalib and even cross-compiles to DOS with djgpp/allegro. Generator uses its own custom 68000 processor emulation which is designed for dynamic recompilation, and uses techniques from this such as block-marking, flag calculation removal, operand pre-calculation, endian pre-conversion etc. There are approximately 1600 C routines generated by the first stage of compilation to cope with the 67 instruction families. These routines are used as a 'backup' when dynamic recompilation isn't supported on your platform or the recompiler doesn't support a particular instruction. The CPU engine is by all accounts very fast, whatever the mode. There is a 'test' recompiler written for the ARM processor, but it is no longer supported. If someone with assembler knowledge wants to put the effort into writing a recompiling back-end for a processor (and it really is major effort), let me know - particularly if you know i386.
