>A lot of these older classics that you'd probably want to emulate are actually available in some form or other.
And emulation is the reason those titles are available. Those titles are being emulated on other systems. Without the games having been pirated to begin with, the people sitting on the IP would have left them to rot. Piracy is a demonstration of demand. Do you think the iTunes Music Store would have come about without Napster?
>Additionally, just because a title isn't easily available for purchase, or available through your desired channels, that doesn't magically invalidate copyright.
"Information wants to be free." It doesn't invalidate the copyright, but it certainly lowers the 'perceived harm' in the mind of the end-user.
And the copyright holders, thankfully, don't seem to be very attentive. Coolroms and EmuParadise are still around, I was grabbing ROMs from there over 10 years ago.
