Does anyone have a “what’s the difference?” file link or post to tell us what each/every version is for as in specializations?

That would be very nice to have…I have plans to build my own arcade in my storage building and i would like to know each/every version to know if it trims the fat in some places or specializes in others.

Thanks in advance to all who have contributed to this project. You have progressed dealing with emulators ahead around a decade and i thank you for that.

You guys are awesome.
