I emulated a bunch of Master System, SNES, NES and Genesis games in january, at my vacation. Only played each one for a couple of hours, do not know if this is the real way to make it leagl, but deleted after 24 hours, as a friend told me is the right way to do it.
It is amazing how many great games are lost in time because the hardware is obsolete. The PS3 was a great way to keep PS1 games alive, but I do not own a PS3 anymore.
I don´t know, life is short, there are other stuff we have to do, how much time one really has to play games, right?
It is like collecting stuff: I think life is too short to collect anything, it´s pointless. If I have no use for something, I give it away.
Sometimes I wish I had it again, but it vanishes really fast.
Emulation is a way to realize you do not really want or need something...
