SirPrimalform: I don't think it's legal
any of the time. The legal equivalent of abandonware would be public domain I suppose.
AacRrc: Well a copyright on a video game can't have run out since video games aren't old enough
Edit: Apparently I can't spell 'video game'
No, but the person owning the copyright can make it public domain if they want to.
The point I was trying to make was that the very definition of abandonware is something that's still in copyright and the copyright just isn't being enforced. Legal abandonware isn't abandonware. :P
