Chrono Trigger is still being sold actually, so probably not the best example. That said, I still have my original PS1 Chrono Trigger disc that I haven’t played on original hardware (or even my still-hooked-up PS3) for a while because I legally dumped it and play it with a much higher emulated disc read speed. As much as Nintendo has made explicit statements to the contrary, it is legal in most countries to back up your own games and do with them what you will.
Damn, this is a shame. Penny’s Big Breakaway has been the most fun I’ve had on a game for a while, but I kind of expected it wasn’t going to be a huge success for people who hadn’t been following the Evening Star team for years with a new and unproven IP and a rather unique gameplay style among platformers.
