/// CD-ROM / DVD (CDVD) resources that is attached through the IOP.

/// No official documentation - everything comes from PCSX2. Thanks to everyone involved!

/// The registers are assigned to the 0x1F402000 -> 0x1F402FFF space.
|
|
/// Notes:
|
|
/// - Follows the psx-style cd-rom setup, such as from the no$psx docs (command register, with parameter and response fifo's).
|
|
/// - 2 types of command and fifo sets - the S_ and N_ sets.
|
|
/// - N_ set controls the raw cd-rom data?
|
|
/// - S_ set controls the mechacon?
|
|
/// - STATUS controls what the emulator is currently doing: ie: nothing, seeking, reading, etc.
|
|
/// This is set upon writing to the N_COMMAND register, where it also resets the INTR_STAT.CmdComplete bit. Use this in order to step the state within the emulator.
|
|
/// INTR_STAT.CmdComplete is set upon completion, and the IOP.INTC.CDROM bit is set.
|
|
/// - N_2005 needs to be set to 0x4E upon boot (ready), seems to use 0x40 after that, or 0x0 if not ready...
