New systems emulated
==General==
 
===BIOS===
Depending on the emulator, BIOSes can be either necessary or an added novelty. Generally, emulators of more modern/complex consoles will require BIOS files in order to operate.
{{Main|Emulator Files}}
See: [[Emulator Files]]===New systems emulated==='''Are there emulators for the PlayStation 4, PlayStation Vita, Xbox 360, or Nintendo Switch?'''
===New systems emulated==='''Is there an emulator Yes! See the following pages for the 3DS, VITA, PS3, Xbox360, Wii U, PS4, Xbox One?'''more information:
There are *[[PlayStation 4 emulators for the PS3 (]]*[[RPCS3PlayStation Vita emulators]]), *[[Xbox 360 ([[Xeniaemulators]]) and 3DS (*[[CitraNintendo Switch emulators]]), however, they are not functional for regular use.As for the other systems, no.
===Specs===Note that all emulators are very early in their development and though they're always getting better by the day, they are not stable.
'''Can I run [insert emulator here]Are there emulators for the Xbox One yet?'''
See: [[Computer specs]]No. <u>Many that you come across on YouTube videos and the like are scams or malware.</u>
===Save states===
'''My save states do not work in the new version of the emulator I downloaded. Why?'''
 
Save states are not compatible between different versions of emulators, or between different emulators. Don't rely on them. Use real/battery saves which typically can be transferred, even if they need to be converted first.
 
==Performance==
'''Can I run this emulator?'''
 
See [[Computer specs]].
'''My save states do not work in the I got a new version of the this emulator I downloaded. Why, and now it's slower! Can this be fixed?'''
Save states are not compatible between different versions of emulatorsWell, or between different emulators. Don't rely on them. Use real/battery saves which typically there can be transfered, even if they need converted firsta number of reasons why it can slow down.
===New *Try closing other programs first. While CPU usage is one factor, games are not the only thing that could be using the <u>disk</u>, especially if you're not using a solid state drive.*It could have been reset to the default CPU priority, which you could have set to max on the old version.*The new version didn't detect the previous settings that sped up the games.*The new version is slower===may have lost support entirely for settings that sped up the games, probably in favor of [[Emulation_Accuracy|accuracy]].
'''The new version of an emulator My PC is slower than the previous versiona toaster. WhyAre there any emulators I can run?'''
As Most emulators developof the 16-bit era (fourth generation) and earlier consoles (e.g., Sega Genesis, they generally become more [[Emulation_Accuracy|accurate]]NES, Atari 2600, etc.) can be run on any PC, emulating more even one with a CPU clock speed of below 1 GHz. higan is the systemonly exception because it's functions. This results in greater compatibility, highly accurate and fewer glitches but at the expense of speed. More requires a 3 GHz CPU power is neededfor optimal performance. It may make sense to use an older version that works well for a specific game if your system is not able to handle the modern versionOther emulators such as Snes9x, Kega Fusion, Mesen, etc. But newer versions may also can be optimized or perform more efficiently as wellrun on any PC that can run Windows.
However, emulators of the fifth generation and later consoles are a different story. While fourth generation and earlier consoles could only display pixel art and, in some cases, very primitive 3D graphics, the move to fifth generation consoles saw a massive jump in consoles' graphical capabilities, with full 3D polygon graphics with texture mapping, lighting and shadows, anti-aliasing, texture filtering, etc. The consoles required much more complex CPUs and GPUs with multiple cores to be able to display these types of graphics. Because of this, emulators of the fifth generation and later consoles require a mid- to high-end gaming PC for optimal performance, with a 3 ~ 3.5 GHz or faster CPU clock speed and at least a mid-range AMD / Nvidia graphics card.
==Filetypes==
===General==='''What does this file extension mean?'''
Check out the We have a [[List list of filetypes]] for information on what's what, and where to use it.
===Archives===
'''I downloaded a compressed archive (zip/rar/7z), but it has a lot of files starting with r00/r01, or part1/part2, or 001/002. What are these?'''
It'''I downloaded s a file split archive in a full archive. Why that happens is beyond us, but all you need to do to use it is to unpack it with whatever software you have, which means WinRAR, WinZip, et cetera. If you do not have either of those and don't have a way to decompress split archives, get [http://www.7-zip.org/rar/7z format7-Zip] and extract all the files to a folder nearby. Then, using your software, select the first archive and inside extract it are a lot of (some programs insert shell extensions that allow you to extract files labelled either r00/r01 etcstraight from the right-click menu), part1/part2 etc or 001/002 etc and you should have all the expected files. What are these?'''You can then delete the archives.

Then, right click on the first in the sequence or (e.g. r00/part1/etcNTSC) and, depending on the program used, should have an "Extract Here" command. Use it; itrefer to?''ll output the files you're looking for. You can then proceed to delete all those r0x/partx/etc files if you want.
[[GoodTools#Good_codes|Codes]]. They mean different things, and we've provided a list telling you their meanings.==[[Controllers|'''Controllers''']]=ECM format====[[DualShock 3]]==='''I have connected my DualShock 3 controller to the computer. Why doesn't it work?'''
If you'''I downloaded a PS1 game from emuparadise. Itre using Windows, that's in .ecm format and won't open in an emulatorbecause there are no official drivers for it. Why?'''
ECM is a compressed format. You need Some developers have taken it upon themselves to decompress using PakkISO or ECM Tools (both provided on the emuparadise download page)make these drivers. It'll output as a .bin usually, which is what the The first one that ever went public was called [[.cueMotioninJoy|MalwareohJoy]] uses to load , but it was plagued with issues, [https://web.archive.org/web/20170715032648/http://betterds3.ciebiera.net/why/ as the game. Note that recent SVN builds author of [[PCSX-R]BetterDS3 wrote in 2013] DO allow loading of ECM files, however it's recommended to unpack them anyway.
==Controllers==So we recommend the [[SCP Driver Package]], and we've written up a bit on using it.===PS3/PS4 controllerDualShock 4==={{Main|DualShock 4}}
==PS1 emulators=====ECM format==='''How do I connect my PS3/PS4 controller to my computerdownloaded a PS1 game. It's in .ecm format and won't open in an emulator. Why?'''
Use ECM is a compressed format. You need to decompress using PakkISO or ECM Tools (both provided on the emuparadise download page). It'll output as a .bin usually, which is what the [[Cue sheet (.cue)|.cue]] uses to load the game. Note that recent SVN builds of [[XInput Wrapper SCPPCSX-Reloaded]]DO allow loading of ECM files, however, it's recommended to unpack them anyway==PS1 emulators=Linux users can use the ECM Tools which should be included in your repository, which is explained on [https://ubuntuforums.org/showthread.php?t=1472552 Ubuntu Forums]. You then need to use the 'ECM-uncompress' command in terminal.
===Keybinds in lilypad===
 '''I use PCSX-R with LilyPad, but the esc ESC key and various others don't work!'''
In the keyboard Input API (radio buttons in the top left of the LilyPad options), choose raw input.
 
===Mednafen save states===
 
'''Save states do not work in [[Mednafen]] PSX. '''
 
Save states are not enabled in Mednafen PSX, and will not be added until the developer feels that the emulator is mostly finished.
===Multi track games===
'''The PlayStation 1 game that I downloaded came with a lot of tracks. How do I play it?'''
'''The PlayStation 1 game that I downloaded came with a lot of tracksYou need to create/run the [[cue sheet (.cue)]]. Support for multi-track games can be found in [[Mednafen]], [[RetroArch]], [[PCSX-Reloaded|PCSX-R]] and [[ePSXe]]. How do I play it?'''
You need to create/run the [[cue sheet (.cue)]]. Support for These multi-track games can be found in [[Mednafen]]are often compressed, the first track is usually ecm'd, the audio files are often converted to the .ape format, [[RetroArch]]to easily extract all of these, and use [[PCSX-Reloaded|PCSX-R]http://www.theisozone.com/downloads/playstation/tools/pakkiso PakkISO]. Using [[ePSXehttp://www.monkeysaudio.com/download.html Monkey's Audio]] does not support such features and should not be usedto decode the ape files sometimes result in files that don't match redump's md5 sum.
===Mednafen memory cards===
{{Main|Using RetroArch#Transfer PS1 Memory Card Files]}}
To transfer memory cards, follow this guide. Also, in games with multiple discs with saves that carry over, you have to follow the same procedure.

==PS2 emulators==
 
===Blurry PS2 ===
 
'''Why is my PS2 game blurry?'''
It's either interlacing or a filter in the game itself. For the former, switching the de-interlacing mode with F5 may help, and may cause flicker or screen shaking. For the latter, hacks are required. Either Aggressive-CRC if the game is listed there, or skipdraw (toy with the number, 1-100) might work otherwise.
 
Simply sitting farther back from the screen (similar to how one would normally sit away from a CRT TV) can also reduce the noticeability of the blur filter.
===Black lines in PS2 games===
Those lines are caused by scaling to a non-integer internal resolution (anything other than XxNative), texture filtering (Check that shit off or to half at most), improperly offset textures(TC offset hack, Wild Arms hack), or improperly handled texture edges(Sprite hack). Native resolution , for the most part , fixes those. But software rendering may be required as well.
