# 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.
