Generator – a game emulator of the Sega Genesis and Mega Drive consoles for GNU/Linux and Windows.

It 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 it’s own custom 68000 processor emulation which is and uses compilation techniques 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 include two versions of every instruction – one that calculates flags and one that doesn’t, so that unnecessary flag computation is avoided.

Generator was first released in August 1998, although it is a first attempt of the author at writing a Sega Genesis / Mega Drive emulator dates back to 1996.
