I'm programming the Vectrex to do a dinosaur game!

This uses asm6809 (see http://www.6809.org.uk/asm6809/ ) to assemble. Type make to build, then make run to open ParaJVE (may need to edit the file to set it's path) and select main from the open other rom option
