How to prepare the .cdi

  1. Verify source integrity: check provided checksum if available.
  2. If using a real Dreamcast:
    • Burn the .cdi to a CD-R at low speed (4x–8x recommended) using burning software that supports .cdi.
    • If your burner/software doesn’t accept .cdi directly, convert to .bin/.gdi with cdi2raw and burn the resulting files as a disc image.
  3. If using an emulator:
    • Try loading the .cdi directly. If unsupported, convert to .bin/.gdi or to a supported format per emulator docs.

How to Play It (The Honest Guide)

If you want to experience this, you need a Dreamcast, a CD burner, and a willingness to ignore your backlog.

  1. Find the CDI: Look for the version released by the developers (Retro Sumus) or reputable scene groups like ReviveDC. Avoid early "beta" CDIs; the final release has all 5 levels and the true ending.
  2. Burn Slow: 16x speed. No, your modern burner doesn't want to do that, but force it. Use ImgBurn with the Padus .cdi plugin. DiscJuggler is ancient software; avoid it if you can.
  3. Boot it: Turn on your DC, hear the "sega" chime, and wait. If you see the swirl logo, you're golden.
