o2em <file> [options]
The file name must include the extension, which is .bin
The most commonly used option would be -fullscreen
Usage:
o2em <file> [options]
<file> = file to load with extension
options:
-wsize=n Window size used by the emulator (1=original, 2=double size, etc.)
-fullscreen Use full screen mode
-scanlines Enable scanlines use by the video emulation. Scanlines are a
feature that makes your display look like a TV screen.
-nosound Turn off sound emulation
-novoice Turn off voice emulation
-svolume=n Set sound volume (0-100)
-vvolume=n Set voice volume (0-100)
-debug Start the emulator in debug mode
-speed=n Relative speed (100 = original speed)
-nolimit Turn off speed limiter
-bios=file Set the file name or directory to find the console bios.
By default it looks for a file named o2rom.bin.
You can use a bios file from an Odyssey2, Videopac or
Videopac+ console. If you want to run VP+ games (in VP+ mode)
then you need a VP+ bios.
-euro This option enables the use of European timing / 50Hz mode.
This option is usually not needed as most of the games that
really require this mode will be auto-detected.
-filter Enable the low-pass audio filter.
-scshot=file Set the screen shot file name or template. The screen shot
will be saved when you press the F8 key in the emulator.
The extension of the file you give will set the file type.
supported file types are bmp, pcx and tga. You can also give
a template to save several files, using the @ character.
Using an option like -scshot=dump@.bmp will save files with
names like dump00.bmp, dump01.bmp, etc. The pictures will
have a resolution of (320x240)*wsize.
-exrom Enable the use of an alternative ROM mapping for 4Kb games, to
support some games that use a special 3kb program rom/1kb data
ROM mode. The only games I know that use it are Four in 1 Row
and Musician and both are detected by their CRC and set
correctly (I least the versions I have). So this option is to be
used only with games that are currently unknown to O2EM. Do not
enable it as default, as it will make all the 4kb games that do
not use this special mode crash.
-s1=mode/keys Define stick 1 mode/keys
-s2=mode/keys Define stick 2 mode/keys
These options define how the console joysticks are emulated.
You can use a joystick connected to your computer or use
the keyboard. You can specify a mode number (compatible with
previous versions of O2EM) to disable the joystick emulation,
to select an actual joystick or to set a default keyboard
emulation mode :
0=Disable,
1=Default Right keys (arrows keys and right shift)
2=Default Left keys (W,S,A,D,SPACE)
3=Joystick
Example: -s1=1 -s2=3
You can also specify a list of 5 keyboard codes that will
be used to emulate the joystick, separated by comas
(without spaces), using this order : UP,DOWN,LEFT,RIGHT,FIRE.
The following codes are accepted (not case sensitive):
A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,
0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
0_PAD,1_PAD,2_PAD,3_PAD,4_PAD,5_PAD,6_PAD,7_PAD,8_PAD,9_PAD,
TILDE, MINUS, EQUALS, BACKSPACE, TAB, OPENBRACE, CLOSEBRACE,
ENTER, COLON, QUOTE, BACKSLASH, BACKSLASH2, COMMA, STOP,
SLASH, SPACE, INSERT, DEL, HOME, END, PGUP, PGDN, LEFT,
RIGHT, UP, DOWN, SLASH_PAD, ASTERISK, MINUS_PAD, PLUS_PAD,
DEL_PAD, ENTER_PAD, PRTSCR, PAUSE, ABNT_C1, YEN, KANA, AT,
CIRCUMFLEX, COLON2, KANJI, LSHIFT, RSHIFT, LCONTROL,
RCONTROL, ALT, ALTGR, LWIN, RWIN, MENU, SCRLOCK, NUMLOCK
Example: -s1=y,h,g,j,lcontrol -s2=8_PAD,5_PAD,4_PAD,6_PAD,RCONTROL
