Optical Discs

Optical Discs

Insert a disc and wait for identification. Play becomes active only after mounting, platform detection, runtime/firmware checks, and virtual-cart setup.

Supported workflows

• PS1 original/backup CD: raw 2,352-byte sector streaming with track-aware CUE
• PS2 CD/DVD: BOOT2 detection, PCSX2 physical-drive mode, or internal rip
• GameCube/Wii backup/data disc: Dolphin when the PC drive can read it
• Dreamcast backup CDI/GDI/MIL-CD layouts
• Strongly identified Sega CD, Saturn, and PC Engine CD backups
• DVD movies, audio CDs, and data discs containing recognizable loose ROMs

Most ordinary PC DVD drives cannot read original Nintendo GameCube/Wii discs or Dreamcast GD-ROMs. PS1 needs scph5501.bin; PS2 and several Sega/PC Engine systems need their matching firmware.

Optical spin-up can take tens of seconds. Re-inserting an identified title reuses its stable save ID. When burning, wait for Finalized/Ejected before removing media. Dual-layer discs work only when both the writer and selected content support them.
