While SonyÃ¢â‚¬â„¢s PlayStation Now service was announced as a new sort of backwards compatibility, a feature that would allow players to stream older games to their PS4 console, new information has suggested PlayStation Now will only be for PS3 games, while the PS4 will actually be able to emulate PS1 and PS2 titles itself.
In fact, Sony may not only implement internal emulation software, but also make it so that the emulation could enhance the graphics by presenting the older games in HD resolutions. The performance of games using internal emulators would be superior to that of those being streamed through something like PlayStation Now, although there is no reason why PS1 and PS2 games could not be added to that service as well.
There are no definite details or official announcements yet, so everything is still in the realm of speculation. However, if Sony implements an actual backwards compatibility service that allows PS1 and PS2 disks to play on the PS4, fans will be ecstatic. Even if only downloaded titles can be played, the emulation decision should still meet with praise.
