NullDC (Dreamcast Emulator) for Windows:

Being the first entry of the 6th generation of video game consoles, the Dreamcast met a moderate success, mostly due to the fact that Sony had announced the upcoming release of the PlayStation 2. This lead to a rather early discontinuation of the console that happened in 2001 in the United States, or only 3 years after its release. Now unavailable in retail, gamers can still enjoy the games released on the console thanks to the NullDC Dreamcast emulator, known to be the best of its kind.

Minimum Requirements

The following are the specs required to be able to run the NullDC Dreamcast emulator. Keep in mind however that being the bare minimum required to run the emulation of Dreamcast games, the performance on lower-end hardware specs may be low, be it in the quality (display and sound), or the speed (Frames per second).

  • Windows 98 / NT / 2000
  • 1.5GHz Processor with SSE2 support
  • 256MB of RAM
  • DirectX 9 Compatible Video Card
  • OpenGL 1.2
  • VisualC++ 2005 Service Pack 1 runtime
  • A USB PC gamepad is also recommended

Recommended Requirements

Rather easy to find on most modern computers, these recommended system requirements ensure that the NullDC Dreamcast emulator will run smoothly with all games and offer a comfortable emulation of the console.

  • Windows XP or later releases
  • 2.6GHz Intel Pentium 4 of higher
  • 512MB or RAM
  • GeForce 3 TI or Video Cards with similar specs
  • OpenGL 2.0
  • VisualC++ 2005 Service Pack 1 runtime
  • A USB PC gamepad is also recommended

Initial Configurations

Before starting the emulation of Dreamcast games, it may be best to ensure that all will go well.

The first thing to do is to ensure that all the above-mentioned requirements are met.

  1. If the hardware requirements are rather easy to verify, the runtime library may not always have the necessary software. It is thus recommended to install VisualC++ 2005 Service Pack 1 runtime if it isn’t present.

  1. The next thing to do is to find a BIOS ROM file. Without it, the Dreamcast emulator will basically be useless and will not run any game. This file can be found easily with a basic Google search.

Main Configurations

Once the above done, the main configurations can start:

  1. First of all, browse to Options > nullDC Settings > Broadcast Format on the emulator. It is generally recommended to choose NTSC rather than PAL as it offers a higher frames per second (FPS) rate.
  2. Next up is the configuration of the controls, also known as the key mapping. To access the setup screen, simply browser to Options > Maple > Port A > Config Keys for Player 1. You will then be prompted to map the different controls to the buttons on the gamepad.
