I don't tend to emulate anything older than Gameboy Advance really. I do believe that ROMs and emulators do act as a time capsule of sorts, preserving old games that you wouldn't be able to find a physical copy of, especially in the horrific rarity of active 90's arcade machines.
I have seen some for sale, either online or in the actual arcades themselves but it's about:
1) Saving the cash for them as some go into the four figure total
2) Having the space to set them up and basically store them at home
Thus emulators provide an alternate to this. I don't believe it's piracy, unless it's anything current generation or even one step back into the PS2/XBOX/Gamecube era, hence why I said I don't tend to use anything later than a GBA really and even then...

Just researched this a bit...U.S. copyright laws state that copyrights owned by corporations are valid for 75 years from the date of first publication. And that whether you have an authentic game or not, or whether you have possession of a ROM for a limited amount of time, i.e. 24 hours, it is illegal to download and play the ROM from the Internet. In case anyone cared...
Edit: Thanks for that insight, definitely food for thought right there
