Sony may finally have an answer to the backwards compatibility debacle on the PS3. Those of you who got duped into buying a PlayStation 3 console without backwards compatibility (I’m guilty of it too), may finally get to enjoy your old PS2 games on your shinier, newer system. The Emotion Engine chip used to be the only way to display older generation games on Sony’s current system; but a new patent filing may change all of that. It seems that the Playstation team may have developed a new software emulator that will allow all Playsation 3 consoles to become backwards-compatible through a firmware update.
Siliconera broke the news earlier today; here’s their take on it:
There are two main ways to emulate hardware. Interpretation is when target code is decoded and converted into a language the host can understand. The other strategy is to decode and recompile programs in the host’s language.
Maybe the concept is better explained another way. Interpretation is like having someone constantly translating English to Japanese for you, non stop, twenty four hours a day wherever you go. Decoding and recompiling is like someone translating a sets of words and putting them in a dictionary you can reference. Sony developed a way to translate instructions from an Emotion Engine chip into chunks that can be referenced.
