Backwards compatibility is set to continue on the PS3 with gamers being able to play PS2 and PSOne games, but how will it work?

Sony have answered the question on the official Playstation web site:

To used save data on a Playstation 2 memomry card, you must copy the data onto a virtual memory card without the hard disk. This requires a PS2/PSOne memory card adaptor to copy the data to your Playstation 3. A memory card adaptor is designed to edit, up/download games saves to and from EMS flash card or smart media card.

Backwards compatibility is an important issue for gamers and Sony fanboys will be delighted that the system in place to transfer these files will be so easy to use.

Sony have not confirmed whether the adaptor will be part of the PS3 package or whether it will be sold seperately.
