# 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.
