The options are as follows:
-H HZ Use a custom frame rate, can be used to accelerate or slow
down emulation.
-P Emulate 50Hz PAL mode (as used in European models of the Mega
Drive).
-R (J|U|E) Emulator region. Without this option, DGen uses the first
region mentioned in the ROM header. It should be combined
with -P for PAL mode. See below.
(none) Autodetect (NTSC, 60Hz)
-P Autodetect (PAL, 50Hz)
-R J Japan (NTSC, 60Hz)
-R J -P Japan (PAL, 50Hz)
-R E Europe (NTSC, 60Hz, music will certainly play too
fast)
-R E -P Europe (PAL, 50Hz)
-R U America (NTSC, 60Hz)
-R U -P Same as -R E -P
