Making a CD image

Required items

  • HE System CD-ROM2 discs
  • PC with a CD-ROM drive.
  • CD Manipulator - Disc imaging software


  1. Download CD Manipulator (an external link), run CdManipulator.exe.
  2. Insert a CD into the disc drive.
  3. Select "Read from CD to image file"
  4. Configure the following points. Without these options CD Manipulator sometimes creates unusable images.
    • UNcheck "Analyze Pregap"
    • UNcheck "Analyze Sub Code (Get Accurately TOC)
    • Check "ignore Read Errors"
UperGrafx uses .cdm .img and .sub files. The writing function is not used for the making image purpose.

Writing CD images to the Memory Card

See the instructions here → CD image transfer software

Switching CD images on the PC Engine

Required items

  • A PC Engine console 
  • Designated System Cards by CD games (We do not suport Arcade Card Duo. However we will support Arcade Card DUO as definitive functions. We support Games Express CD Card as partial)
  • A memory card with CD images installed.
  • A UperGrafx, it is installed CD-ROM2 system 


  1. Insert and connect the required items. Turn on the power.
  2. Press the run button, on the "PRESS RUN BUTTON" screen (#1).
  3. System Card runs the Audio CD player on the first reading disc.
  4. The Audio CD player shows an audio CD which has the same amount of tracks as the number of installed CD images.
  5. Play the audio tracks. Each audio track 5 minutes long.
  6. Choose the same track number as the CD image required. (If you want to switch to image #10, play track #10)
  7. Press SELECT + RUN buttons when the audio player plays a target track number.
  8. PCE shows the "PRESS RUN BUTTON" screen again. Press the RUN botton again.
  9. UperGrafx switches the target CD image.

Force Audio CD mode

  • When a target disc is selected on while paused (not playing). The target disc image is loaded as pure audio disc. 
  • UperGrafx plays silence for data tracks. Some audio tracks say "DO NOT PLAY DATA TRACKS on an AUDIO CD player". This is not a problem for the UperGrafx.

Supplementary note

  • When you reset the PCE by pressing SELECT+RUN buttons on the target disc image, Operation Sequence back to #1.
  • Press turn on again, some CD-ROM2 software does not accept pressing SELECT + RUN buttons.
