Simple Virtual CDROM for macOS

Introduction

  • Use kext (kernel extensions) to simulate a CD-ROM drive
  • Tested on macOS Big Sur
  • Code is extremely simple
  • Only supports loading Audio CD
  • Supports loading CUE sheets
  • Supports loading a series of audio files as tracks

Build

Requirements

  1. Install Xcode, make sure clang & python3 accessible from command-line.
  2. Disable SIP in order to load self-compiled kexts.
  3. Download ffmpeg for macOS.

Build and load kernel driver

  1. Open virtualcdrom.xcodeproj with Xcode.
  2. Press Command-B to build project.
  3. From Product menu, click Show Build Folder in Finder.
  4. virtualcdrom.kext should appear in Products/Debug in build folder.
  5. Load kext with following commands:
    sudo cp -R [DRAG virtualcdrom.kext TO HERE] /Library/Extensions
    sudo kextutil /Library/Extensions/virtualcdrom.kext
    
  6. Approve the kext in System Preferences and reboot.
  7. Verify kext is loaded:
    kextstat | grep virtualcdrom
    

Build and prepare user-space client

  1. Build client
    clang -o client client.c -framework IOKit
    
  2. Copy ffmpeg, let it along with client
    cp /your/path/to/ffmpeg ffmpeg
    
  3. Run ./loadcd.py to verify everything is ok, it should output:
    sending 0 bytes to kernel
      successfully loaded 0 bytes to kernel
    

Let's load CD!

Load a CUE sheet (with one big audio file)

  • Command:
    ./loadcd.py [DRAG CUE FILE HERE]
    
  • Example output of loadcd.py:
    trying utf_8
    loading disk image
      decoding '明日への扉.wav'
    ==================================================
    track 00 start  0:00.00 sector      0 crc ????????
    track 01 start  4:46.59 sector  21509 crc ????????
    track 02 start  9:34.44 sector  43094 crc ????????
    --------------------------------------------------
    total          17:23.02 sector  78227 crc 75ea388c
    ==================================================
    sending 184342704 bytes to kernel
      successfully loaded 184342704 bytes to kernel
    

Or, Load a series of audio files as tracks

  • Command:
    ./loadcd.py [DRAG AUDIO FILES HERE]
    
  • Example output of loadcd.py:
    loading track 00
      decoding '01 明日への扉.wav'
    loading track 01
      decoding '02 明日への扉 (instrumental).wav'
    loading track 02
      decoding '03 エピローグミニドラマ「明日と加瀬さん。」.wav'
    ==================================================
    track 00 start  0:00.00 sector      0 crc a209b77f
    track 01 start  4:46.59 sector  21509 crc a5683510
    track 02 start  9:34.44 sector  43094 crc 0120bcf0
    --------------------------------------------------
    total          17:23.02 sector  78227 crc 75ea388c
    ==================================================
    sending 184342704 bytes to kernel
      successfully loaded 184342704 bytes to kernel
