#### Main Targets ###

compare: $(ROM)
	@md5sum -c checksum.md5

$(ROM): $(ELF)
	$(ELF2ROM) -cic 6105 $< $@

$(ELF): $(O_FILES) build/ldscript.txt
	$(LD) -T undefined_syms.txt -T build/ldscript.txt --no-check-sections --accept-unknown-input-arch -o $@

build/ldscript.txt: $(SPEC)
	$(CPP) -P $< > build/spec
	$(MKLDSCRIPT) build/spec $@

clean:
	$(RM) $(ROM) $(ELF) -r build
