# Vectorgons -- Commodore 64 build
# ---------------------------------------------------------------------------
# Cross-compiles the C64 edition with cc65 and packs it onto a .d64 disk
# image with VICE's c1541.
#
#   make            -> vectorgons.prg  (raw C64 program, loads at $0801)
#   make d64        -> vectorgons.d64  (bootable disk image)
#   make run        -> build + launch in the VICE x64sc emulator
#   make clean
#
# cc65 need not be on PATH: set CC65_HOME / CL65 to point at an extracted
# install if it lives somewhere non-standard, e.g.
#   make CL65=/path/to/cl65 CC65_HOME=/path/to/share/cc65
