Overview[edit | edit source]

These are the device numbers of the "peripherals" connected to IOP.

DEV1[edit | edit source]

The DVD player ROM (on SCPH-18000 and later). This is often physically a part of the same IC as the boot-ROM (DEV2).

DEV2[edit | edit source]

The boot-ROM.

DEV3[edit | edit source]

USB

DEV4[edit | edit source]

SPU2

DEV5[edit | edit source]

DEV8[edit | edit source]

Originally, the parallel port of the PS1. on the PS2 it is unused on retail models, but even the DECKARD emulator still has code for handling DEV8. seems to be recycled for PowerPC UART. On DTL-T models, the DRP interface (for debugging with DECI2) is connected.

DEV9[edit | edit source]

SSBUS controller (on SCPH-3000X and later) or PCMCIA controller (on SCPH-1x000) as well as devices connected to these (SPEED).
