=head1 NAME

stella - an Atari 2600 emulator

=head1 SYNOPSIS

B<stella> I<options> I<ROM file>

=head1 DESCRIPTION

B<stella> is a comprehensive emulator of the old Atari 2600 video-game
console. It support most Atari 2600 games and many peripherals.

If you start Stella and do not specify a ROM image, it will start in
'ROM Launcher' mode. If this is your first time starting Stella, you
will be asked to select the default ROM directory to use.

This man page only documents the command-line options and default
keybindings. The complete documentation is in I<index.html> and
I<debugger.html>, usually installed in I</usr/share/doc/stella/> or
I</usr/doc/stella-4.7.2/>.

=head1 OPTIONS

=over 4

=item B<-video> <direct3d|opengl|opengles2|opengles|software>

Use the given rendering backend (where applicable); default is the best
available mode detected.

=item B<-vsync> <1|0>

Synchronize screen updates to the vertical blank period. This can
result in smoother updates, and eliminate tearing.

=item B<-fullscreen> <1|0>

Enable fullscreen mode.

=item B<-center> <1|0>

Centers game window (if possible).

=item B<-palette> <standard|z26|user>

Set the palette to either normal Stella, the one used in the z26
emulator, or a user-defined palette.

=item B<-colorloss> <1|0>

Enable/disable the PAL color-loss effect.

=item B<-framerate> <number>

Display the given number of frames per second. Normally, Stella will
determine framerate based on number of scanlines. Setting this to 0
automatically enables auto-frame calculation (ie, framerate based on
scanlines).

=item B<-timing> <sleep|busy>

Determines type of wait to perform between processing frames. Sleep
will release the CPU as much as possible, and is the preferred method
on laptops (and other low-powered devices) and when using VSync. Busy
will emulate z26 busy-wait behaviour, and use all possible CPU time,
but may eliminate graphical 'tearing' in software mode.

=item B<-uimessages> <1|0>

Enable or disable display of message in the UI. Note that messages
indicating serious errors override this setting, and are always shown.

=item B<-sound> <1|0>

Enable or disable sound generation.

=item B<-fragsize> <number>

Specify the sound fragment size to use. Linux/Mac seems to work with
512, Windows usually needs 1024.

=item B<-freq> <number>

Set sound sample output frequency (11025,22050,31400,44100,48000)
Default is 31400. Do not change unless you experience sound issues.

=item B<-volume> <number>

Set the volume (0 - 100).

=item B<-tia.zoom> <zoom>

Use the specified zoom level (integer) while in TIA/emulation mode.

=item B<-tia.inter> <1|0>

Use interpolation for the TIA image (results in blending/smoothing of
the image).

=item B<-tia.aspectn> <number>

=item B<-tia.aspectp> <number>

Specify the amount (as a percentage) to scale the TIA image width in
NTSC and PAL mode. Since many video modes do not use square pixels, you
can reduce width until the pixels appear square. Allowable values are
80 - 120; I find 85 - 90 gives the most authentic look for NTSC, and
105 - 110 for PAL.

=item B<-tia.fsfill> <1|0>

Stretch TIA image completely while in fullscreen mode (vs. an integral
stretch which won't necessarily completely fill the screen).

=item B<-tia.dbgcolors> <roygbp>

Assigns the colours (R)ed, (O)range, (Y)ellow, (G)reen,
(B)lue and (P)urple to each graphical register P0/M0/P1/M1/PF/BL,
respectively. Currently, these can be changed around to apply different
colours to the respective register.

=item B<-tv.phosphor> <always|byrom>

When to use phosphor mode.

=item B<-tv.phosblend> <0 - 100>

Set default blend level in phosphor mode.

=item B<-tv.filter> <1 - 6>

Blargg TV effects, 0 is disabled, next numbers in sequence represent
presets for 'Composite', 'S-Video', 'RGB', 'Bad Adjust', and 'Custom'
modes.

=item B<-tv.scanlines> <0 - 100>

Blargg TV effects scanline intensity, where 0 means completely off.

=item B<-tv.scaninter> <1|0>

Blargg TV effects scanline interpolation, resulting in
blending/smoothing of the scanlines.

=item B<-tv.jitter> <1|0>

Enable TV jitter effect.

=item B<-tv.jitter_recovery> <1 - 20>

Set recovery time for TV jitter effect.

=item B<-tv.contrast> <number>

Blargg TV effects 'contrast' (only available in custom mode, range -1.0
to 1.0).

=item B<-tv.brightness> <number>

Blargg TV effects 'brightness' (only available in custom mode, range
-1.0 to 1.0).

=item B<-tv.hue> <number>

Blargg TV effects 'hue' (only available in custom mode, range -1.0 to
1.0).

=item B<-tv.saturation> <number>

Blargg TV effects 'saturation' (only available in custom mode, range
-1.0 to 1.0).

=item B<-tv.gamma> <number>

Blargg TV effects 'gamma' (only available in custom mode, range -1.0 to
1.0).

=item B<-tv.sharpness> <number>

Blargg TV effects 'sharpness' (only available in custom mode, range
-1.0 to 1.0).

=item B<-tv.resolution> <number>

Blargg TV effects 'resolution' (only available in custom mode, range
-1.0 to 1.0).

to 1.0).

=item B<-tv.bleed> <number>

Blargg TV effects 'bleed' (only available in custom mode, range -1.0 to
1.0).

=item B<-cheat> <code>

Use the specified cheatcode (see Cheat section for description).

=item B<-loglevel> <0|1|2>

Indicates level of logging to perform while the application is running.
Zero completely disables logging (except for serious errors), while the
remaining numbers show increasingly more detail.

=item B<-logtoconsole> <1|0>

Indicates that logged output should be printed to the
console/commandline as it's being collected. An internal log will still
be kept, and the amount of logging is still controlled by 'loglevel'.

=item B<-joydeadzone> <number>

Sets the joystick axis deadzone area for joysticks/gamepads. All values
within the deadzone are treated as zero-axis values, while only those
values outside are registered as valid input. Accepts a number from 0 -
29, and uses the formula 3200 + number * 1000. So the possible deadzone
values range from 3200 to 32200.

=item B<-joyallow4> <1|0>

Allow all 4 directions on a joystick to be pressed simultaneously.
Bumper Bash ignores this setting, and always allows all 4 directions.

=item B<-usemouse> <always|analog|never>

joystick digital axis or button, keyboard key, etc). Valid range of
values is from 1 to 20, with larger numbers causing faster movement.

=item B<-msense> <number>

Sensitivity for emulation of paddles when using a mouse. Valid range of
values is from 1 to 20, with larger numbers causing faster movement.

=item B<-tsense> <number>

Sensitivity of mouse emulated trackball movement (1-20).

=item B<-saport> <lr|rl>

Determines how to enumerate the Stelladaptor/2600-daptor devices in the
order they are found: 'lr' means first is left port, second is right
port, 'rl' means the opposite.

=item B<-ctrlcombo> <1|0>

Use control-x key combos. This is normally enabled, since the Quit
command is tied to 'Control-q'. However, there are times when a
2-player game is using either the 'f' or 'r' keys for movement, and
pressing Control (for Fire) will perform an unwanted action associated
with Control-r or Control-f.

=item B<-autoslot> <1|0>

Automatically switch to the next available save state slot after saving
a ROM state file.

=item B<-stats> <1|0>

Overlay console info on the TIA image during emulation.

=item B<-launcherfont> <small|medium|large>

Set the size of the font in the ROM launcher.

=item B<-launcherexts> <allfiles|allroms|LIST>

Specifies which files to show in the ROM launcher ('allfiles' is
self-explanatory, 'allroms' is all files with valid rom extensions
(currently: a26, bin, rom, gz, zip), 'LIST' is a ':' separated list of

fatal errors are simply logged, and emulation continues. Do not use
this unless you know exactly what you're doing, as it changes the
behaviour as compared to real hardware. Note that Thumb ARM emulation
only applies to the BUS, CDF, and DPC+ cartridge types.
