Now you will need a 65C02 cross assembler. The code was developed using [xa](http://www.floodgap.com/retrotech/xa/), mainly because it was available as a prebuilt binary in my preferred Linux distro's package repositories and supported the 65C02 opcodes.
|

Now you will need a 65C02 cross assembler. The current codebase is developed using ca65 from the [cc65](http://www.cc65.org/) project. (Note: The code was developed originally using [xa](http://www.floodgap.com/retrotech/xa/)).
|

|

Finally you will need [Ruby](https://www.ruby-lang.org/en/) and [Rake](https://github.com/ruby/rake).
