 The '''PlayStation 4[[wikipedia:Sega Dreamcast|Dreamcast]]''' (PS4) is an eightha sixth-generation console produced released by Sony Computer Entertainment [[wikipedia:Sega|Sega]] on November 1527, 2013 1998 in Japan and later on September 9, 1999 in NA. It retailed for $399{{Inflation|USD|199.99 ($432.54 in 2018 money)|1999}}. It has had a semiHitachi SH-custom 8-core AMD x86-64 Jaguar 4 RISC CPU at 1200 MHz with 16 MB of RAM and 8 MB of VRAM.6 GHzIt had a PowerVR2 GPU at 100 MHz, whereas one which theoretically was capable of the cores is utilised separately only for lowpushing 3 million polygons/second on-power, background tasksscreen. The CPU There is shared on an APU chip a 2 MB audio RAM, which complemented a powerful 67 MHz Yamaha AICA sound processor, with a semi32-custom AMD GCN Radeon GPUbit ARM7 RISC CPU core. They are supported by 8 GB The audio chip could generate 64 voices with PCM or ADPCM codec and provided ten times the performance of GDDR5 RAM at 2the [[Sega Saturn emulators|Saturn's]] sound system.75 GHz, while 256 MB of DDR3 RAM is used only for background tasks. Notably, it is the first PlayStation console to use Sega also released the '''[[wikipedia:x86Sega NAOMI and variants|x86Naomi]] architecture''', making it easier an arcade system board with similar components to program for than the Dreamcast. Sammy's '''[https://segaretro.org/Atomiswave 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 [[PlayStation 3 Xbox emulators|PlayStation 3Xbox]] while also having . What came out of this was the same architecture as PCspossibility 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).

It supports Windows CE games, but in general, a trait that would typically lead they run worse than standard Dreamcast titles. It's also more resource-intensive than other emulators.;[[redream]]: Multi-platform and easy to years of development time by emulatorsuse, but it opens 's closed-source. Compatible with [https://redream.io/compatibility 90+% of the ability Dreamcast library] (Windows CE now supported), 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 presave states.;[[nullDC]]: Can run a lot of games at great speed on mid-existing hypervisors to do end PC and it's open-source, however, it's no longer developed and the heavy liftingmore recent forks have improved upon it.:;[[reicast]]: Eventually, nullDC's author forked his own project into reicast, eliminating with the need for a recompilermain objective to widen platform availability to smartphones and tablets. There While wider availability is alsogenerally a good thing, as of writing this, little resulted in cutting accuracy corners from the nullDC codebase to achieve the speed goals necessary to no documentation run on these platforms. Advancements in mobile hardware should have led to the GPU (a modified Radeon 7970M with disabled stream processors) used removal of such "hacks"; however lack of developer resources and interest led to long delays in Reicast development, and the PS4's APUcodebase 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 it will require as a complete re[[libretro]] core. Libretro collaborators, primarily [https://github.com/flyinghead/reicast-implementation by emulator developersflyinghead], dramatically improved Reicast in areas such as graphics, input, system clock, and Dreamcast VMU. EndAtomiswave and NAOMI SH-4-users may wish based arcade systems have also been added to preform a preliminary dump of the required files from their PS4 using the [great fanfare<ref name="flycastnaomi">https://phigithub.nzcom/libretro/orbitalflycast/toolsissues/dumper136</ Orbital Dumperref>, along with support for MAME's popular CHD format. Even full MMU support, which is needed to run WinCE-based games such as "Armada", "Half-Life" and "SEGA Rally Championship 2", 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. ;[[Makaron]]: One of the only two closed-source Dreamcast emulators that can properly play Windows CE games. ==Emulation issues==For the emulators that are either mature or maturing, a very large percentage of games work well, but some games still have problems and glitches. ==VMU emulators==While some 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.
