PS5, the future flagship of Sony, could really be backwards compatible with PS1, PS2, PS3, at least so we are suggested by a new patent.
Sony has in fact filed a new document that should report the operation of the much desired backward compatibility. As reported by IGN US, it seems that the Japanese company has aimed at digital emulation via the cloud, and not physical. The content of the patent is as follows:
“A large number of PS1 / PS2 / PS3 games can be stored via the cloud game library. These can run on a virtual machine that simulates the operating system of the respective consoles ".
As shown in the image above, the various consoles are read by different virtual machines, which subsequently store the game read in one dedicated title library to the aforementioned game platform.
Everything must be taken with pliers of course, at least until Sony releases official information.
