The editor is here: http://www.playsoft.co.uk/aplayed.html
There are instructions here: http://www.playsoft....structions.html
There is an example design here: http://www.playsoft.co.uk/mwalk.apl which you can load and play about with in the editor.
And finally there is a little test .xex file here: http://www.playsoft.co.uk/test.xex which uses the above design. It requires 48k, not that it's big it's just how I've laid out memory.
