# Configuration for overlay programs (overlays located below main program)

# The overlay files don't include the 4 byte DOS 3.3 header so use AppleCommander like this:
# java -jar ac.jar -cc65 mydisk.dsk myprog   bin < myprog
# java -jar ac.jar -p    mydisk.dsk myprog.1 bin < myprog.1
# java -jar ac.jar -p    mydisk.dsk myprog.2 bin < myprog.2
# java -jar ac.jar -p    mydisk.dsk myprog.3 bin < myprog.3
# ...
