[-r RCFILE] [-X XFACT] [-Y YFACT] [-S FACT] [-G XxY] [-s SLOT]


The rom image in the file romname is executed, as emulated on a Sega
Genesis or MegaDrive running in 60Hz NTSC mode (unless the -P option is
specified, in which case 50Hz PAL mode is used). romname should be in
raw binary or SMD format, and may be compressed with gzip(1), zip(1), or

The options are as follows:

-P Emulate 50Hz PAL mode (as used in European models of the

-R If running with root priviledges, set priority to -20, so no
other processes interrupt (including the X server, which can
be a Bad Thing).

-f Run fullscreen, if possible.

-h Show a brief synopsis of all options.

-j Use joystick, if running on Linux with joystick drivers >=

-v Show the version number, and exit.

Record a demo of the program running, which can be later
replayed with the -D switch.

-n USEC Sleep for a number of microseconds after every frame, to give
time to other processes.

Modify the ROM image in memory, using Game Genie or Hex style
codes. Game Genie codes are of the form ABCD-EFGH and Hex
codes are in the form 123456:ABCD. To specify more than one
code, separate them with commas (do not use spaces).

-r RCFILE Parse another rc file after $HOME/.dgen/dgenrc. Values in the
specified file override those in the preceding files.

-X XFACT Scale the window XFACT times in the X direction. XFACT must
be a positive integer.

-Y YFACT Scale the window YFACT times in the Y direction. YFACT must
be a positive integer.

-S FACT Scale the window FACT times in both directions. FACT must be
a positive integer.

-G XxY Use OpenGL to render the screen, if available. The parameter
is the width and height of the desired screen (e.g. 640x480,
800x600, etc.)
