Re: How to dump your CDROM BIOS (Firmware)

Re: PSX cdrom sector buffer capacity
to NO$CASH: "accordingly, the PSX can use only three of the available eight SRAM slots: One for currently pending INT1, one for undelivered INT1, and one for currently/incompletly received sector)." so sub-cpu holds space in RAM for only 3 sectors? then if no reading from Host (ps1) it ove...
