# Execute either the real dasm, or dasm2atasm + atasm.
# If we have dasm on the PATH, use it, otherwise fake it.
# dasm2atasm is NOT perfect! It does however work OK for
# fenders.dasm, fendersdbl.dasm, and loadscreen.dasm.
# The .syms file format is totally different for dasm and atasm, but
# fenders_offsets.pl can handle either one (adapt for your purposes).
# If you have dasm, but want to force atasm, pass any non-empty string
# as the second argument to this script.
# Could also use "dasm2atasm -c" and ca65/ld65 to assemble, but I can't
# seem to get ca65 or ld65 to emit a symbol file or listing (the -l
# option doesn't work; the -m option doesn't do what I expect), so
# I don't know any way to extract the OFFSET_* labels from ca65's output.
