Wot he said.

Also, Keyclone has created sample maximizer templates for a lot of popular configurations so you can run X number of instances "right out of the box"

You download the layout, save it to the same folder you have keyclone in, and then in maximizer click 'I' to import a template.

If you want to save your template or make several you click 'X' on the same screen to export (save) the layout.

I found the sample layouts to be extremely helpful, both on their own and showing me the general gist of how to do it.

I tinkered with resolutions on one of them as I customized to myself, big thing I made sure was to maintain the resolution ratios as 4:3 to try to not impact fps.
