 SEGA Genesis emulator
 
-I ported to FreeBSD with all sound support off.
-If you want the sound support, you hack.
+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 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 has been installed.
+
+If you enabled the option SDL_AUDIO and your sound is delayed try setting the
+variable "sound_maxfields" and "sound_minfields" in your configuration file
+(usually "~/.genrc") to lower values. Like:
+
+# default: 5
+sound_minfields = 1
+
+# default: 10
+sound_maxfields = 2
+
+To gain more performance set the CPUTYPE variable in "make.conf" as appropiate
+(in addition to enabling the build option OPTIMIZED_CFLAGS), then rebuild and
+install generator.
+
+NOTE: if you want more features use the port "emulators/generator-cbiere".
