3 lxdream - A dreamcast emulator
7 lxdream [options] [disc-image-file] [program-file]
15 =item B<-A>, B<--audio>=I<audio-driver>
17 Set the preferred audio driver. If the specified audio driver cannot start, the system
18 will try all other available drivers in the standard order. To see which drivers are
19 supported, run lxdream -A ?
21 =item B<-c>, B<--config>=F<config-filename>
23 Load configuration information from F<config-filename> instead of the system default
25 =item B<-d>, B<--debugger>
27 Launch the debugger on startup (GTK platforms only).
29 =item B<-h>, B<--help>
31 Print command line usage information
33 =item B<-H>, B<--headless>
35 Run in headless mode (no GUI or video output). This is mainly useful for testing CPU
36 functions and performance. Equivalent to -V null.
38 =item B<-l>, B<--log>=I<log-level>
40 Set the system log level to the specified level of verbosity, which must be one of the following options:
41 FATAL, ERROR, WARN, INFO, DEBUG, TRACE (non-case-sensitive, and only the first letter is required). The
42 default level is WARN.
44 =item B<-m> B<--multiplier>=I<scale>
46 Change the SH4 core clock speed using the supplied floating-point multiplier, where 1.0
47 is full speed, 0.5 is half speed, and so on. The default is 0.5.
51 Don't start running on startup, even if a disc or program file was supplied. By default
52 the system will start automatically if a disc or program was given on the command line.
56 Start running on startup, even if no disc or program file was supplied. By default
57 the system will only start automatically if a disc or program was given on the command
60 =item B<-t>, B<--run-time>=I<seconds>
62 Run the dreamcast for exactly the specified amount of time, and then terminate, ie
63 lxdream -pt 5.2 will exit after 5.2 seconds of emulated runtime. Useful for performance
64 measurements of arbitrary sections of code.
66 =item B<-T>, B<--trace>=I<trace-list>
68 Activate I/O region tracing for the specified list of MMIO regions. This option is only
69 available if lxdream was configured with --enable-trace. If enabled, trace-list may be
70 a comma-separated list of 1 or more of the following: ALL, ASIC, AICA0, AICA1, AICA2, AICARTC,
71 EXTDMA, PVR2, MMU, UBC, BSC, DMAC, CPG, RTC, INTC, TMU, SCI, and SCIF.
73 Warning: this option implicitly sets the verbosity level to 'trace', and will generate a huge
76 =item B<-u>, B<--unsafe>
78 Allow unsafe dcload syscalls. Without this option, the only permitted calls are reads, writes, and
79 seeks on stdin, stdout and stderr. If you're writing your own code that uses the other syscalls, you
80 probably want to enable this. Otherwise it's safer to leave it off.
82 =item B<-v>, B<--version>
84 Print the lxdream version string.
86 =item B<-V> I<video-driver>
88 Set the preferred video driver. If the specified video driver cannot start, the system
89 will exit with an error. To see the available video drivers, run lxdream -V ?
93 Disable the SH4 translator and run in pure emulation mode. Generally you only want to do this for testing
94 purposes (ie if you think you've found a translator bug) as it's much slower this way.
102 =item B<$HOME/.lxdreamrc>
104 Default user configuration file. This will be created at startup if it doesn't
105 already exist, unless an alternative file is specified with -c.
