Yes, a reinstall of an Image will allways make your player workable again.
you could also make a backup of the original executable :

# rw
# cp /empeg/bin/player /empeg/bin/player.org
# ./setvisual /empeg/bin/player /tmp/image.bin
# ro

to restore the orginal executable :

# rw
# cp /empeg/bin/player.org /empeg/bin/player
# ro
