First you need a copy of the EV Bible and the editor of your choice (this FAQ assumes ResEdit is the editor being used, some concerns mentioned here may already be taken care of in other third-pary editors). A copy of this FAQ and the starter plug-in can be found in the EV Plug-in Package located on Ambroisa's web site and the Escape Velocity web site. If you plan on creating new graphics or sounds to include with your plug-in, you will need programs for creating and editing these new resources. And lastly, you will need a copy of EV to test your work.
