Troubleshooting

Dreamcast issues

A Dreamcast game will not launch or has performance problems.

Start here

  1. Identify the selected Dreamcast emulator.
  2. Check its supported game format and firmware requirements.
  3. Try stock settings and confirm game files transferred completely.
  4. Capture the launch error or exact graphical symptom.
What usually causes this?

Emulator-specific game/firmware requirements, graphics or configuration.

Advanced explanation

Different Dreamcast emulators and revisions have different requirements. Confirm the installed version before applying an old workaround.

Still stuck?

Record what changed after each check. Include your exact board, image, emulator and error when asking for help. These are diagnostic starting points, not guaranteed fixes for every OS.
