It utilizes ;[[PSP Eboots|EBOOTshigan]]:Also developing cycle-accurate Genesis emulation, a form of binary file for PSP, instead of bin/cue disc dumps, which can be made using a converter if desired. Compatibility is very high due to similar hardware design; although the GPU is emulated, the CPU is close akin to the PS1 and would naturally speed up performance on its very own. It includes support for multi-disc games (within the one EBOOT). Only the native PS1 resolution is supported, with games being stretched to fit the screen as the user wishes. * PCSX-ReARMed is only available on mobile as a libretro core (e.g. RetroArch). It is available to run on various handheld consoles with fairly strong specs like the Sony PlayStation Vita, [[Super Nintendo 3DS and Nintendo Switch. This emulators|SNES emulator in the libretro build initially used the P]] bsnes.E.Op.S. graphics plugin (reasonably accurate, but slow) in mid-2010's to 2019; now it uses a port of PCSX4ALLIt's Unai renderer, which is less accurate, promising but much faster (eg. 10-20fps faster). The CHD compression format, that shrinks disc images into more manageable sizes, has been enabled on this emulator on 3DS, and these images will load and run much faster than '.bin/.cue' files - greatly reducing framerate dips, i.e. in FMVs & loading zones. * PS2PSXe is an unofficial PS1 emulator for the PS2incomplete.

Many PlayStation games dither to varying degrees due to having a low color depth. On most TVs, this dithering would blend in order to make new colors and smooth gradients. Plugin-based emulators usually have graphical plugins that use a 32-bit color depth, which removes dithering, while software-rendered plugins and emulators tend to retain it. While higher color depth The Sonic & Knuckles cartridge can be considered an enhancement, since it results in less noise and smooth gradients, some think of dithering as seen lock on real hardware as added shading and texture, especially on untextured polygons. The emulators that use software rendering and can increase the internal resolution are capable of retaining dithering for the shading and texturing aspect, and it's made more subtle by shrinking the artifacts.to other cartridges:

Even running an ISO file based on a PS1 game bin (Sonic & Knuckles (i.e. ''Ridge Racer, Tomb Raider 1-2''MiB) ROM) with CD-DA audio may often cause an emulator such as '''ePSXe''' and other peers to freeze and/or hang up, especially during loading of a saved data or in-game levels and transactions.* However, a mounted image sk2chip.bin (Sonic & Knuckles UPMEM (Using '''Daemon Tools'''256 KiB), running from a CD-ROM or using the ): If you can'''Mooby2''' plugin can solve these CD-DA problems. The mds/mdf format is good for backing up the CD-DA audio-equipped PS1 games, although the best Image format for any PS1 game is the cue/bin formatt find it online, the reason being that almost all of the burning programs can read extract it and the relevant patching programs (i.e. '''PPF-O-Matic''') are designed for that format. '''Clone CD''' images in img/ccd format provide another ideal option as it has virtually the same structure as cue/bin format (The img file is the same data as with a bin file at the hex level), although editor from a pre-combined Sonic 2 & Knuckles ROM from offset 00300000 to the available burning programs are largely not able to read Clone CD's format. '''ISObuster''' and '''ImgBurn''' are good tools for some end of the aforementioned notes.<ref name="ECM-APE_Guide">{{cite web|url=https://wwwROM.epforums.org/showthread.php?57757-ECM-And-APE-Guide|title=ECM And APE Guide |publisher=www.epforums.org|accessdate=2018-Oct-05|date=2011-Feb-16; Last edited: 2017-Jan-15}}</ref>

* The European regional versions of many PS1 games tended to have a copy protection embeddedFor GG/AR, so they could cause problems with backing up images in that these game backups could cause hangs or show a black screen infinitely in a typical emulator. A basic way to avoid that problem is to try the US regional versions. Another way is to patch it using a .sbi file which contains the protection information files needed to run the gameare areplay.::The perfect solution possible, at least for the '''ePSXe''' emulator (bin and perhaps other similar plugins-based emulators) would be (No virtual drive mounting needed):::1. Use '''Mooby2 2ggenie.8''' cdrom pluginbin, uncheck 'subchannel reading' in the settings of that plugin.::(Just in case: also make sure 'repeat all cdda' is checked, and 'cdda volume' is set to something like 50 or 60. Or else you won't hear anything.)::2. Launch the game with File -> Run CDrom (browse, find and select your cd image as the window pops up.)::Recommended to use '''Eternal 1.41''' sound plugin with default settings along with this. '''SaPu''' CDRom Plugin v.1.0/1.3 is good if running official CDs (Especially works well with '''Daemon Tools Lite''' or '''Alcohol 120%''' when mounting an image)but most emulators support cheat codes from these natively.

* If running '''ePSXe''' or a similar emulator on an old '''Windows''' OS (Eg. 9x, ME, 2000, XP), use [http:==Mega Drive Plus //radified.com/ASPI/forceaspi.htm ForceASPI] to initialize the ASPI layer (For your disc drive) and a plugin like '''P.E.Op.S.''' CDR Version 1.4 plugin or similar. Then set the plugin to "W2K/XP IOCTL scsi commands" before running your PS1 CD's.Genesis Plus==
