Sega Dreamcast
DreamcastConsole.png
Developer Sega
Type Home video game console
Generation Sixth generation
Release date 1998
Discontinued 2001
Predecessor Sega Saturn
Emulated

The Dreamcast is a sixth-generation console released by Sega in November 1998 in Japan and later in 1999 in other territories. Sega also released the Naomi, an arcade system board with similar components to the Dreamcast. Sammy's Atomiswave arcade board was also based on the Dreamcast and Naomi.

Sega collaborated with Microsoft on the Dreamcast's development, and this partnership would continue later with the Xbox. What came out of this was the possibility for games to be developed for an optimized version of Windows CE (with DirectX) on each disc. However, Windows CE wasn't mandatory to use and most developers opted for Sega's development tools instead out of convenience. Even in major emulators, this aspect isn't implemented (or implemented well).

Comparisons

DEmul
Has the highest compatibility and accuracy, but is Windows-only. It supports Windows CE games, but in general, they run worse than standard Dreamcast titles. It's also more resource-intensive than other emulators.
NullDC
Can run a lot of games at great speed in mid-end PCs. It's no longer developed in favor of its fork…
reicast
Made by the same team. Runs on Android, Windows, and Linux.
Reicast regular and Reicast OIT
libretro forks similar to Mednafen's PCE-fast and PCE-accuracy cores that backport changes from flyinghead's fork of reicast. regular aims to be compliant with OpenGL 2 and OpenGL ES 2 so that it can continue to run on mobile devices and mid-tier PCs. A graphics feature of the Dreamcast, Order-Independent Transparency, can only be properly emulated using recent versions of OpenGL 4, so a fork was made to leverage that features on supported platforms (currently Windows and Linux).[1] These forks also support Naomi and Atomiswave hardware.
redream
Has a good interface, is simple to set up and can run without a BIOS (though it's better to use one anyway).
Makaron
One of the only two Dreamcast emulators that can properly play Windows CE games.

Emulation issues

Dreamcast emulation isn't very good. For the emulators that are either mature or maturing, a very large percentage of games work well, but many games still have problems and glitches.

In recent times, the open-source community has gotten a better leg to stand on thanks to RetroArch's reicast cores. Their team has been integrating a version of reicast that deals with many graphical issues (elaborated on above).

Poor VMU emulation

While current Dreamcast emulators can leverage the screen of the VMU while the game is running, none of them allow you to play the minigames developed for it so playing those minigames would require another emulator. The problem is there aren't any complete lists of VMU emulators, and the emulators that can be found are poorly documented and/or closed source.
