quality, medium lag', 'high quality, medium lag', 'high quality, low lag' and
'ultra quality, minimal lag'.
-audio.fragment_size <number>
Set the number of samples in a single fragment processed by the audio driver.
number must be a power of two between 128 and 4096 inclusive. Under Debian the
recommended value is 512.

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.
-tia.correct_aspect <1|0>
Enable aspect ratio correct scaling.
-tv.filter <0-5>
Blargg TV effects, 0 is disabled, next numbers in sequence represent presets for
"Composite", "S-Video", "RGB", "Bad Adjust" and "Custom" modes.
-tv.sharpness <number>
Blargg TV effects 'sharpness' (only available in custom mode, range -1.0 to 1.0).
-tv.resolution <number>
Blargg TV effects 'resolution' (only available in custom mode, range -1.0 to 1.0).
-tv.artifacts <number>
Blargg TV effects 'artifacts' (only available in custom mode, range -1.0 to 1.0).
-tv.fringing <number>
Blargg TV effects 'fringing' (only available in custom mode, range -1.0 to 1.0).
-tv.bleed <number>
Blargg TV effects 'bleed' (only available in custom mode, range -1.0 to 1.0).
-tv.phosphor <always|byrom>
Determines how phosphor mode is enabled. If always, then the ROM properties entry
is ignored, and phosphor mode is always turned on. Otherwise, the ROM properties
determine whether phosphor mode is used for each ROM.
-tv.phosblend <0-100>
Enable phosphor blending level; 0 implies no mixing, and 100 is full mixing (not
recommended). Note that this doesn't actually enable phosphor mode; that is done
for each ROM in the ROM properties. Higher blend values will intensify the phosphor
effect. Depending on your display and personal preferences, the optimal default for
you may vary. Slow LCDs (especially for office use) may only need a low blend of
around 30, while fast switching gamer LCDs may need about 70 to look similar to a
CRT.
-tv.scanlines <0-100>
TV effects scanline intensity, where 0 means completely off.
-cheat <code>
Use the specified cheatcode (see the Cheat section in the provided documentation
for a description of cheatcodes).
-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.
-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.
-joydeadzone <number>
Sets the joystick deadzone area for analog joysticks. Accepts a number from 0 - 29,
and uses the formula 3200 + number * 1000. So the possible deadzone values range
from 3200 to 32200.
-psense <number>
Sensitivity for emulation of paddles when using analog paddles. Valid range of
values is from 1 to 30, with larger numbers causing faster movement
-dejitter.base <0-10>
Strength of paddle input averaging.
-dejitter.diff <0-10>
Impact of fast paddle movement on input averaging.
-dcsense <number>
Sensitivity for emulation of driving controllers when using a mouse. Valid range
of values is from 1 to 20, with larger numbers causing faster movement.
-autofirerate <0-30>
Automatic trigger rate of the fire buttons in Hz (0 = disabled)
-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.
-modcombo <1|0>
Use modifier (Shift/Alt/Control)-x key combos. This is normally enabled, since the
'Quit' command is tied to 'Control-q'. However, there are times when you want to
disable them. E.g. 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 default keys.
-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.
-avoxport <name>
Set the name of the serial port where an AtariVox is connected.
-usemouse <always|analog|never>
Use mouse as a controller as specified by ROM properties in specific case. always
and never are self-explanatory, analog means only for analog-type devices (paddles,
trackball, etc.).
-msense <number>
Sensitivity for emulation of paddles when using a mouse. number may range from 1 to
20, with larger numbers causing faster movement.
-tsense <number>
Sensitivity for emulation of trackball controllers when using a mouse. number may
range from 1 to 20, with larger numbers causing faster movement.
-dsense <number>
Sensitivity for emulation of paddles when using a digital device (joystick digital
axis or button, keyboard key, etc.). number may range from 1 to 20, with larger
numbers causing faster movement.

The following are available in two sets, one for players (prefixed by plr.) and one for
developers (prefixed by dev.). Only use them if you know what you're doing! Note that in
all cases, the values supplied to the arguments are not case sensitive.
-dev.settings <1|0>
Select developer (1) or player (0) set.
-<plr|dev>.stats <1|0>
Overlay console info on the TIA image during emulation.
-<plr|dev>.detectedinfo <1|0>
Display detected settings info when a ROM is loaded.
-<plr|dev>.console <2600|7800>
Select console for B/W and Pause key handling and RAM initialization.
-<plr|dev>.bankrandom <1|0>
On reset, randomize the startup bank (only for selected bankswitch types).
-<plr|dev>.ramrandom <1|0>
On reset, either randomize all RAM content, or zero it out instead.
-<plr|dev>.cpurandom [SAXYP]
On reset, randomize the content of the specified CPU registers.
-dev.tiadriven <1|0>
Set unused TIA pins to be randomly driven high or low on a read/peek.
-dev.rwportbreak <1|0>
Since the 2600 has no dedicated R/W line, different addresses are used for RAM read
or write access. If the code reads from such a write address, this causes an
unwanted, semi-random write to that address. When this option is enabled, such
reads interrupt emulation and the debugger is entered.
-dev.wrportbreak <1|0>
Same as above. If the code writes to such a read address, nothing happens. But a
developer should be made aware of it, because this indicates a problem with the
code. When this option is enabled, such writes interrupt emulation and the
debugger is entered.
-plr.thumb.trapfatal <true|false>
The default of true allows the Thumb ARM emulation to throw an exception and enter
the debugger on fatal errors. When disabled, such 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.
-<plr|dev>.eepromaccess <1|0>
When enabled, each read or write access to the AtariVox/SaveKey EEPROM is signalled
by a message.
-dev.tia.type <standard|koolaidman|cosmicark|pesco|quickstep|heman|custom>
Set emulated TIA type.
-dev.tia.plinvphase <1|0>
Enable/disable inverted HMOVE clock phase for players (Kool Aid Man glitch).

Enable/disable playfield color delayed by one color clock (colored step borders in
Quick Step!).
-dev.tia.delaybkcolor <1|0>
Enable/disable background color delayed by one color clock (stray pixels in Indy
500 menu hack).
-dev.tia.delayplswap <1|0>
Enable/disable player swap delayed by one color clock (He-Man title glitch).
-dev.tia.delayblswap <1|0>
Enable/disable ball swap delayed by one color clock.
-<plr|dev>.tv.jitter <1|0>
Enable TV jitter/roll effect, when there are too many or too few scanlines per
frame.
-<plr|dev>.tv.jitter_recovery <1-20>
When TV jitter/roll effect is enabled, determines how long to delay recovery time

Enable/disable the PAL color-loss effect.
-<plr|dev>.debugcolors <1|0>
Enable/disable the fixed debug colors.

Defines the Time Machine buffer size.
-<plr|dev>.tm.uncompressed <0-1000>
Defines the uncompressed Time Machine buffer size. Must be less than Time Machine
the buffer size.
-<plr|dev>.tm.interval <1f|3f|10f|30f|1s|3s|10s>
