# 20091011 bkw: Wrapper script for sms_sdl, does the following:
|
|
|
|
# - Savestates and screenshots will be saved in ~/.sms_sdl/
|
|
# - A ~/.sms_sdl/config file will be read if present, and converted to
|
|
# command-line options for the real sms_sdl binary.
|
|
|
|
# To make things work properly, we have to run the real emulator binary
|
|
# with its cwd set to ~/.sms_sdl/, and create a symlink to the ROM file
|
|
# in the same directory. After the emu exits, we remove the symlink.
|
|
|
|
# 20160804 bkw: various fixes and enhancements.
|
|
# - Make --filter <mode> and --fskip <n> options work from
|
|
# the command line. They work already in a config file, which is why
|
|
# I didn't notice they were broken for *7 years*.
|
|
# - Fix the usage message so it doesn't show the /usr/libexec/ path.
|
|
# - Make the return value of the script match the return value of the emulator.
|
|
# - Add support for single-file zipped ROMs, since I have so many of them.
