wanted to do some work with the ancheron VM...started with the basics...
makefile is given which uses ca65
but I am on windows.
gnu make installed.
cc65 installed.

I run make which would execute:
rm -r obj
rm -r bin
mkdir obj
mkdir bin
ca65 -l obj/acheron.o.lst src/acheron.asm -g -o obj/acheron.o ...
