Ultra One: PS2 on PS3 & onboard flash memory
by Bhavin Shah
A report in a Japanese technology magazine has suggested that Sony will include PlayStation 2 hardware inside each PS3 to achieve backwards compatibility at launch.
Sony had claimed at the PlayStation Business Briefing in February that backwards compatibility would be achieved through software emulation. But according to Ultra One magazine, first edition PS3s will ship with the core PS2 chipset.
Since the software emulation required for backwards compatibility will require significant time and effort, hardware-independant backwards compatibility will be included in later revisions of the PS3. This will reduce production costs because the PS2 chipset will no longer be needed.
Whilst this does guarantee almost fault-free backwards compatibility at launch, it does raise questions about the visual improvements we will see with PlayStation 2 games. Hardware emulation is likely to mean the games will run similar to how they did on their original consoles.
The magazine did go on to reveal that the PS3 will feature onboard flash memory. Phil Harrison, president of SCE Worldwide Studios, has revealed that a standard PC hard drive can be used in the PS3, but there was some confusion over how the PS3 would then retain essential files like system updates. However, Ultra One suggests that the flash memory would store the PS3's OS and any critical updates. Presumably, then, the hard drive will be used exclusively for multimedia content and game caching.
Furthermore, if, in the future, changes in chip design cause problems with particular games, users will be able to connect to Sony's online service and download updates to fix these issues.
Could this mean that a system update will allow software emulation on the first PS3s, and therefore the visual improvements we're expecting?
