Actually Gaelco's (SH4) and Cave's (SH3) arcade hardware are not Dreamcast (SH4) based, Demul supports SH CPU based machines. And if you think Dreamcast emulators should support them, why not add a Capcom's medal machine and other developers' SH CPU based arcade hardware? https://youtu.be/ChYWgvxJ0EU?si=NqujOKmUdBfFYUSj. p1pkin uploaded many videos about Demul. Gaelco, Cave, Capcom and other SH based arcade hardware should be moved to another page?

;[[nullDC]]
:Can run a lot of games at great speed on a mid-end ranged PC, and it's open-source. However, it's no longer being developed, and the more recent forks have improved upon it.
:;[[reicast]]
::Eventually, nullDC's author forked his own project into reicast, with the main objective to widen platform availability to smartphones and tablets. While wider availability is generally a good thing, this resulted in cutting accuracy corners from the nullDC codebase to achieve the speed goals necessary to run on these platforms. Advancements in mobile hardware should have led to the removal of such "hacks"; however, lack of developer resources and interest led to long delays in Reicast development, and the codebase remained virtually untouched for years before the RetroArch team began working with it as part of a "Reicast core", later named Flycast.
::;[[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 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. Also , 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. 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 The emulator works unstably on AMD GPUs with an 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.
