The Yaroze doesn't contain the OS and libraries. The "OS", as it is, is (AFAIK) quite small and just deals with the opening sequence and booting a disk (and the audio UI and similar). Professional games have the libraries linked into their executable files, whereas Yaroze games expect them to be resident in the machine in advance, and that's what the boot disc does. > The access card gives us access to write to the 2MB of ram right? Only in an abstract sense. The RAM is always available for writing, and all PSX games will write to the RAM (since they'll be loaded into it, amongst other things!). The access card is just a dongle that the bootdisk looks for as it starts up. The program on the bootdisk then allows you to *download* into the RAM. > Does it re-write everything so we can't use F.M.V. No. The only reason is that playing FMV from memory would be pointless (after all, you couldn't hold very much in 2MB). Playing full FMVs would require that you could write them onto a CDROM, and Sony can't take the risk of allowing that on a hobby system since the architecture could then be misused by pirates.
