Emulating the Sega Dreamcast on a third-party platform has always been a difficult undertaking. Emulation of the Sega Dreamcast in a way resembles the console itself: it’s promising, attractive, but inherently flawed and underdeveloped. Enthusiastic fans of the Dreamcast tried and succeeded in developing viable emulators capable of supporting some commercial and homebrew games. Nonetheless, the problems that tended to arise during the emulation process were too considerable to ignore. Thus, over time, only one emulator – NullDC – survived. At the present time, it’s the only emulator that can emulate the Sega Dreamcast games, albeit with minor bugs, periodical crashes, and freezes. Last but not least, NullDC is not demanding in hardware requirements. It’s not necessary to own a high-end computer to achieve decent emulation of your favorite Dreamcast game on your PC. Even a dual-core CPU will suffice to support this emulator.

How to Get the NullDC Emulator

Nowadays, people tend to look for answers to all their questions on the Internet. So, if you need to download the NullDC emulator don’t hesitate to search for this useful tool on the web. NullDC has its official website you’re free to visit and avail yourself of the newest version available on the website. Click on the file you want to download. Once it’s downloaded, you may proceed to installing the new program on your computer.

How to Install NullDC

Just like many other emulators, NullDC won’t work without a special file called BIOS. Currently, there are two files for NullDC distributed online – dc_boot.bin and dc_flash.bin. As a matter of fact, they are not separate files but rather two constituents of the software securing proper operation of the emulator. Go search the Internet for the BIOS for NullDC. Just make sure to download them from a reliable resource to avoid catching a virus and installing malware.

The first step you need to take is to decompress the file containing the emulator, as the majority of all emulators come in archives.  Then, place the BIOS file into a data directory.

  • Don’t worry if your system throws you a DLL error at this point. To fix it quickly, you’ll need to install the 2008 version of the Microsoft Visual C++ Redistributable Package.

Once BIOS is put into a proper folder, you may head to the File menu and select the “Normal Boot” option from there. At this point, your emulator should prompt you to choose an ISO, in other words, a game you can run on the emulator.

How to Get Dreamcast ISOs

ISOs, also known as ROMs, are images of the Dreamcast games you once played on a physical console. Sega Dreamcast ROMs can be downloaded from the Internet. You may google for a specific game you want to play on your new emulator or find a reliable website devoted to retro games and distributing ROMs for a variety of emulators. We recommend visiting ROMsMode. This reputable website boasts a vast collection of the most popular Dreamcast games you’ll be able to run on NullDC. Just select click on the name of the console you want to emulate and you’ll land on the page featuring the selected console’s ROMs. Choose your favorite among the variety of games you used to play in your childhood and start enjoying it on your modern computer.

Configuring NullDC

NullDC is notorious for its “reluctance” to support any controllers other than a keyboard, which may be a disappointing fact to old-school gamers that find it particularly charming to use gamepads to control retro games. If you’re also eager to make your gameplay more retro-like try using third-party programs such as Joy2Key, which will allow you to map your gamepad keys to in-game controller buttons.

And more good news for you! Using NullDC enables you to change the default resolution of the game. It means that you’ll be able to play classic Dreamcast titles in both fullscreen and windowed mode on your computer.

Have fun playing immoral Dreamcast classics on your computer with NullDC!
