Simulating a machine for testing?

When I try to test out my configurations it doesn't work without my card and motors hooked up. Is there a program to simulate my hardware?
I found this "EMC2 Pure Simulator" but it's not clear this does what I am looking for. The title looks promising.

I am using the Pico Universal pwm controller.
When I click on EMC2 all I get is the error box without the hardware attached. Not sure how to even try Sims?

No I would like to test out my custom modifications like when I add a pyVCP panel or really any other modification to see if it works right.
Probably not available and maybe not even possible. I stumbled on the "EMC2 Pure Simulator" and got my hopes up.

Has anyone made a comp for a Mesa or Pluto card that I can try to copy? I have to do most of my configuring by the "Forgery" method since I don't understand this stuff enough to make an original.

Oh Yea. I have three machines out in my garage that is heated but with the cost of fuel I keep it low enough to keep me comfortable when I wear a jacket. On top of that the chips are everywhere and it is congested with other stuff. I start my programs and run in the house. I use a baby monitor to hear when my cutting is done. I have wireless to link my computer to the garage computer. Anything to keep me in the house would be super valuable.

I use the installed version and every option I can put in like pendant, touchscreen, and working on my ATC. This is fun stuff especially since I don't know diddly about why all this works.
