# SaveStateFix
#
# A small tool to fix savelocation of some emulators

# Nothing awesome, just a bit of cosmetics

# 25/02/18 - Initial version

#
# What is needed for init? MANDOTARY!!!
# Emulatorname for case selection - Parameter 1 > $2
# ROM itself for copying files - Parameter 2 > $3
#
# Parameter 3: Optinal system $1 or all, to select place of retroarch.cfg
# if Parameter 3 is missing then 'all' is set as standard config
#
