.SH CONFIG FILE
|
|
\fBsms_sdl\fR is launched by a shell script wrapper which reads the
|
|
file \fI~/.sms_sdl/config\fR if it exists. Any of the options above may
|
|
be placed in this file (one option per line, with or without the leading \fB--\fR characters). These options
|
|
will be passed as command\-line arguments to the real \fBsms_sdl\fR
|
|
binary every time it runs.
|
|
.PP
|
|
See \fB/usr/doc/sms_sdl-@VERSION@/sample_config\fR for further information.

.SH FILES
|
|
.PP
|
|
ROM image files may be in raw dump format, or may have a header (details
|
|
are system-specific). Also, ROM images may be zipped (not gzipped), in
|
|
which case the first file in the zip file's directory must be the
|
|
ROM image (any other files are ignored).
|
|
.PP
|
|
\fBsms_sdl\fR looks at the filename to determine the type of ROM image
|
|
in use. Any file whose name ends in \fI.gg\fR (case-insensitive match)
|
|
is considered to be a Game Gear ROM. Any other file is treated as a
|
|
Sega Master System ROM. In the case of a zipped image, this refers to the
|
|
file inside the zip file; the zip file itself doesn't have any special
|
|
naming requirements.
|
|
.PP
|
|
Screenshot filenames (F1 key) are generated by replacing the filename
|
|
extension with \fI-NNN.bmp\fR, where NNN is a 3-digit number (000 for
|
|
the first screenshot, 001 for the second, etc). The numbering starts
|
|
at 000 every time the emulator is started, and existing files will be
|
|
overwritten without confirmation.
|
|
.PP
|
|
State save filenames (F2 key) are generated by replacing the filename
|
|
extension with \fI.stN\fR, where N is the number of the save slot (one
|
|
or more digits). Again, existing files are overwritten without confirmation.
|
|
.PP
|
|
For both types of file, the filename is considered to be the entire
|
|
path to the ROM image file. This means that the emulator expects to
|
|
be able to write savestate and screenshot files in the directory where
|
|
the ROM files reside. If the directory is not writable, no files will
|
|
be created.
|
|
.SH BUGS
|
|
.PP
|
|
\fBsms_sdl\fR will exit with failure status if it's given a filename that
|
|
contains no . (dot/period) characters (in other words, a filename
|
|
without an extension). So don't do that. (This applies to the file
|
|
inside the zip file, for zipped images)
|
|
.PP
|
|
Screenshot and state-save files should really be written in the
|
|
current directory, or else a hypothetical ~/.sms_sdl directory.
|
|
.PP
|
|
There should be a config file, so the user doesn't have to pass his
|
|
favorite set of options on the command line every time (of course,
|
|
a shell alias, wrapper script, or GUI file manager
|
|
can work around this easily enough).
