Ok can someone advise.(pls help a newbie)

I have original verson of psfreedom which i run via xterminal which works fine on games i currently have backed up on my external and internal hdd. What does this new version offer me that my current one does not? did i read that you no longer need an original game in discdrive to boot ? I dont want to lose what i already have working as they say if it aint broken dont fix it!!
