Slow Load time for Play Testing

I've been playing around with NESMaker Engine, following the YouTube tutorials. So far I am pretty happy with the engine and can see a lot of potential. There is one thing that is a bit off putting which is load time for play testing the game. When I want to test the game it takes about 45 seconds to a minutes to load the emulator. My computer is old-ish but it has an i5 Core processor which I understand isn't the greatest but isn't the worst either.

Does anyone else have this problem? Is there something I can do to increase the speed to play test the game I am working on?

Mine only takes a few seconds. I have an i5. Not sure what the problem could be.

Strange. Could just be my computer being slow.

Check your antivirus? (Add an exception for the NESMaker folder).
Your NESMaker folder is on an external drive?
It will be after if your data (NESMaker folder) is on a rapid drive (I presume on a SSD would be the best).
