This simulator replaces the CD/DVD drive on Dance Dance Revolution arcade cabinet System 573. It acts as a DVD optical drive so you can use ISO images of CD or DVDs such as the Extreme Pro SuperDisk. It has no moving parts like the standard CD/DVD drives so you get faster loading times and more reliability.

The IDE simulator can effectively replace CD and DVD-ROM drives in legacy computer hardware such as PCs and arcade PCBs by allowing you to use an SD card or a USB flash drive containing ISO or BIN/CUE files. With no moving parts, less power consumption than an optical drive and a small profile, it can be installed in place within the device enclosures without any impact to performance.

This device simulates an IDE ATAPI CD/DVD ROM drive, with a number of features: Dual host USB SD card slot 44kHz, 16-bit stereo audio, 180MHz Cortex-M3 CPU

    • Implements ATAPI specification
  • Multiple storage formats
    • USB host
      • USB0: high speed
      • USB1: full speed
    • SD card support
    • All storage supports >4GB files
    • ISO and BIN/CUE formats supported
    • Supports SCSI over ATA to implement standard CD and DVD drives
  • Audio output
    • Dedicated audio DAC for audio playback, supporting full 16-bit 44kHz stereo output

Supported platforms

  • Konami 573
  • Namco 246 & 256
  • FreeDOS, MS-DOS 6.22 on 486 and above
  • MacOS X, Windows 10 and Linux via USB IDE adapter
  • Roland SP808


ISO Search

When the device boots, it searches SD:, USB0: and USB1: in that order, for supported disk images. It will recursively enter directories as it encounters them, so it may search a subdirectory on a disk before finding a file (e.g. it may find usb0:/a/game.iso before it finds usb0:/game.iso). This is dependent on the order in which files are stored in the filesystem on disk.

Supported formats


ISO files are supported. By default, the firmware will assume a normal sector size of 2048 in mode1 (as per a normal CD or DVD), but it will inspect the contents for an ISO9660 header to detect certain other sector sizes (e.g. CD-i formats, used by at least one Namco246 game).


To support other formats explicitly, alongside audio tracks, the game will also look for CUE files. Regardless of whether they're a single BIN file, or split into BIN/WAV, the firmware will attempt to parse the CUE correctly and load all relevant files automatically. This provides support for various CD-i/Mode2/etc. formats.

Port Speeds

USB0 is the fastest port, running at USB high speed (480Mbps). Via a USB OTG cable, you can connect a USB Flash drive and store your disk images there for maximum possible access speed. Thus, this is the recommended solution.

SD is the second fastest port. Almost as fast as USB0, but the port can be a little tricky to insert.

USB1 is the slowest port, running at USB full speed (12Mbps). Though it will support a disk if it's connected, this configuration isn't recommended, though is fine for firmware upgrades, connecting to a computer for command line access, and general I/O (e.g. ethernet, external control pads, and other future features)
