[TUTORIAL] Dreamcast in 2026: play on the real console (GDEMU, openMenu, online play) and on PC with Flycast

[TUTO] Dreamcast en 2026 : jouer sur la vraie console (GDEMU, openMenu, jeu en ligne) et sur PC avec Flycast

The Dreamcast is still alive in 2026: emulated drive on an SD card, online play with DreamPi, or the Flycast emulator on PC and Android, here are the right methods.


On the real console: replacing the drive

The GD-ROM drive is the part that fails most often. The most widespread solution is an optical drive emulator (ODE), which replaces it with an SD card:
  • GDEMU: the reference, but official sales are suspended (its author put his projects on hold in April 2026). What is sold is mostly clones, of variable quality: buy from a reputable seller and read the feedback.
  • MODE (Terraonion) and USB-GDROM: other solutions, more expensive or with a different design.

Preparing the SD card with GDMENU Card Manager

The safest way to fill the card is GDMENU Card Manager (2.0.1, for Windows, Linux and macOS):
  1. Format the SD card as FAT32.
  2. In the Card Manager, choose the openMenu menu (an interface with box art; version 1.3.0 of sbstnc's fork is the most recent).
  3. Add your games, copied from your own discs, in GDI or CDI format (even inside a zip, rar or 7z archive).
  4. The software creates the 01 folder (the menu) and a numbered folder per game, with the short names GDEMU requires.
Do not organize the card by hand: a file name that is too long, a wrongly numbered folder or a badly made GDI image is enough to block a game.


Without modification: burned CDs

Early Dreamcasts read burned CD-Rs in CDI format, thanks to the MIL-CD feature. Later consoles, with BIOS version 1.022 (around late 2000), lost it. Burn at the slowest speed and verify the burn.


Copying your own GD-ROMs

Three methods, depending on your hardware: httpd-ack with the network adapter (Broadband Adapter), SDRip with an SD adapter on the serial port, or DreamShell (4.0.4) with an IDE drive or an SD card. You get a GDI image.


Playing online in 2026
  • DreamPi (2.1, September 2026): an image for Raspberry Pi (every model except the Pi 5) which, with a USB modem and a phone cable, reconnects the Dreamcast to the Internet. The list of compatible games is on dreamcastlive.net.
  • Phantasy Star Online runs on community servers, such as Sylverant.

On PC and Android: Flycast

Flycast (version 2.7, August 2026) is the reference Dreamcast emulator, now translated into French. It is available for Windows, Linux (Flathub), macOS, Android (Play Store) and even Xbox. Not for iPhone: its author gave up on it.
  • The BIOS is optional for the Dreamcast (it is mandatory for Naomi and Atomiswave arcade games). If you have your console's BIOS, name it dc_boot.bin and put it in Flycast's data folder.
  • Add your games folder in Settings > Content Location.
  • Graphics: Vulkan or OpenGL, Internal Resolution at 3× or 4× (beyond that, the gain is small), Transparent Sorting set to Per Triangle. The Widescreen Game Cheats option gives true widescreen on compatible games.
  • Online: Settings > Network > DCNet, with no router configuration, for about twenty games (ChuChu Rocket, Worms World Party…).

The most common errors
  • A game does not boot on GDEMU: incorrect file names or GDI image. Let the Card Manager organize the card.
  • The burned CD does not launch: console with BIOS 1.022, without MIL-CD.
  • Flycast slow on a phone with a Mali chip: avoid “Per Pixel” sorting.
  • DreamPi does not boot: the Raspberry Pi 5 is not supported.
For other consoles, see Emulation on PC and Emulation on Android.
