::;[[Flycast]]:::Fork of reicast available as a standalone emulator and as a [[libretro]] core. Libretro collaborators, primarily [https://github.com/flyinghead/reicast-emulator flyinghead], dramatically improved Reicast in areas such as graphics, input, system clock, and Dreamcast VMU. Atomiswave and NAOMI SH-4-based arcade systems have also been added to great fanfare<ref group=N name="flycastnaomi">https://github.com/libretro/flycast/issues/136</ref>, along with support for MAME's popular CHD format. Even full MMU support, which is needed to run Windows CE-based games such as ''Armada'', ''Half-Life'', and ''SEGA Rally Championship 2''. It has recently been tackled through an experimental branch (anyone following Dreamcast emulation over the years understands what a tough nut this is to crack). Aside from some audio stuttering issues in games such as "Looney Toons Space Race" and "Resident Evil: Code Veronica", this is a highly compatible and accurate emulator. Most Windows CE games run at low performanceAlso there is a [https://github.com/flyinghead/flycast/issues/1390 feature request] for implementing an LLE renderer similar to the redream one.:::;Flycast Dojo::::Fork of Flycast with a focus on netplay features and replay. Also, available on the [[Fightcade|Fightcade]] matchmaking service.

;[[redream]]: Multi-platform and easy to use, but it's closed-source. Compatible with [https://redream.io/compatibility +96% of the Dreamcast library (as of Q1 2022)]. It has a good user interface, is easy to set up, and can run without a BIOS. Runs on [https://youtu.be/rywLHa1i9yk?t=529 low-end machines] provided that they support OpenGL 3.1. There's a payware premium version that provides high-definition rendering and additional slots for save states. Emulator work unstable on AMD GPUs with actual driver version. Recently, redream developer "inolen" implemented an LLE video renderer that utilizes a compute shader (like [[Recommended_N64_plugins#Video|parallels-rdp for Nintendo 64]]) that allows [[High/Low_level_emulation|low-level]] graphics emulation to be run on the GPU. This can provide acceptable performance to those who want more of an accurate experience with some decent GPU to handle it comfortably. Since using a computer shader will net you some massive performance benefits, it could also allow you to upscaling/downscaling in the same manner that [[Recommended_N64_plugins#Video|parallels-rdp]] can which can be a lot of fun too. See [https://discord.gg/zuEAVTG redream discord channel] for more information.

:A closed-source Dreamcast emulator that was once noteworthy for being one of the few two, along with Demul, that could properly play Windows CE games. It has since been superseded by newer emulators.
