.SH "NAME"
stella \- an Atari 2600 emulator
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBstella\fR \fIoptions\fR \fI\s-1ROM\s0 file\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBstella\fR is a comprehensive emulator of the old Atari 2600 video-game
console. It support most Atari 2600 games and many peripherals.
.PP
If you start Stella and do not specify a \s-1ROM\s0 image, it will start in
\&'\s-1ROM\s0 Launcher' mode. If this is your first time starting Stella, you
will be asked to select the default \s-1ROM\s0 directory to use.
.PP
This man page only documents the command-line options and default
keybindings. The complete documentation is in \fIindex.html\fR and
\&\fIdebugger.html\fR, usually installed in \fI/usr/share/doc/stella/\fR or
\&\fI/usr/doc/stella\-4.7.2/\fR.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-video\fR <direct3d|opengl|opengles2|opengles|software>" 4
.IX Item "-video <direct3d|opengl|opengles2|opengles|software>"
Use the given rendering backend (where applicable); default is the best
available mode detected.
.IP "\fB\-vsync\fR <1|0>" 4
.IX Item "-vsync <1|0>"
Synchronize screen updates to the vertical blank period. This can
result in smoother updates, and eliminate tearing.
.IP "\fB\-fullscreen\fR <1|0>" 4
.IX Item "-fullscreen <1|0>"
Enable fullscreen mode.
.IP "\fB\-center\fR <1|0>" 4
.IX Item "-center <1|0>"
Centers game window (if possible).
.IP "\fB\-palette\fR <standard|z26|user>" 4
.IX Item "-palette <standard|z26|user>"
Set the palette to either normal Stella, the one used in the z26
emulator, or a user-defined palette.
.IP "\fB\-colorloss\fR <1|0>" 4
.IX Item "-colorloss <1|0>"
Enable/disable the \s-1PAL\s0 color-loss effect.
.IP "\fB\-framerate\fR <number>" 4
.IX Item "-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).
.IP "\fB\-timing\fR <sleep|busy>" 4
.IX Item "-timing <sleep|busy>"
Determines type of wait to perform between processing frames. Sleep
will release the \s-1CPU\s0 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 \s-1CPU\s0 time,
but may eliminate graphical 'tearing' in software mode.
.IP "\fB\-uimessages\fR <1|0>" 4
.IX Item "-uimessages <1|0>"
Enable or disable display of message in the \s-1UI.\s0 Note that messages
indicating serious errors override this setting, and are always shown.
.IP "\fB\-sound\fR <1|0>" 4
.IX Item "-sound <1|0>"
Enable or disable sound generation.
.IP "\fB\-fragsize\fR <number>" 4
.IX Item "-fragsize <number>"
Specify the sound fragment size to use. Linux/Mac seems to work with
512, Windows usually needs 1024.
.IP "\fB\-freq\fR <number>" 4
.IX Item "-freq <number>"
Set sound sample output frequency (11025,22050,31400,44100,48000)
Default is 31400. Do not change unless you experience sound issues.
.IP "\fB\-volume\fR <number>" 4
.IX Item "-volume <number>"
Set the volume (0 \- 100).
.IP "\fB\-tia.zoom\fR <zoom>" 4
.IX Item "-tia.zoom <zoom>"
Use the specified zoom level (integer) while in TIA/emulation mode.
.IP "\fB\-tia.inter\fR <1|0>" 4
.IX Item "-tia.inter <1|0>"
Use interpolation for the \s-1TIA\s0 image (results in blending/smoothing of
the image).
.IP "\fB\-tia.aspectn\fR <number>" 4
.IX Item "-tia.aspectn <number>"
.PD 0
.IP "\fB\-tia.aspectp\fR <number>" 4
.IX Item "-tia.aspectp <number>"
.PD
Specify the amount (as a percentage) to scale the \s-1TIA\s0 image width in
\&\s-1NTSC\s0 and \s-1PAL\s0 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 \s-1NTSC,\s0 and
105 \- 110 for \s-1PAL.\s0
.IP "\fB\-tia.fsfill\fR <1|0>" 4
.IX Item "-tia.fsfill <1|0>"
Stretch \s-1TIA\s0 image completely while in fullscreen mode (vs. an integral
stretch which won't necessarily completely fill the screen).
.IP "\fB\-tia.dbgcolors\fR <roygbp>" 4
.IX Item "-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.
.IP "\fB\-tv.phosphor\fR <always|byrom>" 4
.IX Item "-tv.phosphor <always|byrom>"
When to use phosphor mode.
.IP "\fB\-tv.phosblend\fR <0 \- 100>" 4

.IP "\fB\-loglevel\fR <0|1|2>" 4
.IX Item "-loglevel <0|1|2>"

Zero completely disables logging (except for serious errors), while the
remaining numbers show increasingly more detail.
.IP "\fB\-logtoconsole\fR <1|0>" 4
.IX Item "-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'.
.IP "\fB\-joydeadzone\fR <number>" 4
.IX Item "-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

Sensitivity for emulation of paddles when using a digital device (ie,
joystick digital axis or button, keyboard key, etc). Valid range of
values is from 1 to 10, with larger numbers causing faster movement.

port, 'rl' means the opposite.
.IP "\fB\-ctrlcombo\fR <1|0>" 4
.IX Item "-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.

(currently: a26, bin, rom, gz, zip), '\s-1LIST\s0' is a ':' separated list of
valid rom extensions.
.IP "\fB\-romviewer\fR <0|1|2>" 4
