It is only used in a functional state inside the [[PSX]]. In the PSX, it uses the same 8 MByte chip brand and model that is also used inside official memory cards. However, reverse engineering has shown that the driver for XFROM has code for handling chips with a capacity of 8, 16, 32, 64 and 128 MByte.

SCPH-5xxxx consoles also have the drivers to access it (rom0:XFROMMAN & rom0:XFLASH) and the OSDSYS was updated to upload these drivers to the IOP and look for updates on XFROM following the same path convention that is used for memory card updates. Yet, there are no known variants of the [[Network Adaptor]] containing the compatible variant of [[SPEED]] | SCPH-5xxxx consoles also have the drivers to access it (rom0:XFROMMAN & rom0:XFLASH) and the OSDSYS was updated to upload these drivers to the IOP and look for updates on XFROM following the same path convention that is used for memory card updates. | ||
