New systems emulated[edit]

Are there emulators for the PlayStation 3, Xbox 360, Wii U, or 3DS?

Yes! See the following pages for more information:

Note that all emulators are very early in their development and though they're always getting better by the day, they are not stable.

Are there emulators for the PlayStation Vita, PlayStation 4, Xbox One, or the Switch yet?

No. Any that you come across on YouTube videos and the like are scams.

Save states[edit]

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 transfered, even if they need converted first.


Can I run this emulator?

See Computer specs.

I got a new version of this emulator, and now it's slower! Can this be fixed?

Well there can be a number of reasons why it can slow down.

  • Try closing other programs first. While CPU usage is one factor, games are not the only thing that could be using the disk, 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 may have lost support entirely for settings that sped up the games, probably in favor of accuracy.


What does this file extension mean?

We have a list of filetypes for information on what's what, and where to use it.


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's a 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 7-Zip and extract all the files to a folder nearby. Then, using your software, select the first archive and extract it (some programs insert shell extensions that allow you to extract files straight from the right-click menu), and you should have all the expected files. You can then delete the archives.


What does [!] or (NTSC) refer to?

Codes. They mean different things, and we've provided a list telling you their meanings.


DualShock 3[edit]

I have connected my DualShock 3 controller to the computer. Why doesn't it work?

If you're using Windows, that's because there are no official drivers for it.

Some developers have taken it upon themselves to make these drivers. The first one that ever went public was called MotionInJoy, but it was plagued with issues, as the author of BetterDS3 wrote in 2013.

So we recommend the SCP Driver Package, and we've written up a bit on using it.

PS1 emulators[edit]

ECM format[edit]

I downloaded a PS1 game from emuparadise. It's in .ecm format and won't open in an emulator. Why?

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 uses to load the game. Note that recent SVN builds of PCSX-R DO allow loading of ECM files, however it's recommended to unpack them anyway. Linux users can use the ECM Tools which should be included in your repository, which is explained on Ubuntu Forums. You then need to use the 'ecm-uncompress' command in terminal.

Keybinds in lilypad[edit]

I use PCSX-R with LilyPad, but the 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.

Multi track games[edit]

The PlayStation 1 game that I downloaded came with a lot of tracks. How do I play it?

You need to create/run the cue sheet (.cue). Support for multi-track games can be found in Mednafen, RetroArch, PCSX-R and ePSXe.

These multi track games are often compressed, the first track is usually ecm'd, the audio files are often converted to the .ape format, to easily extract all of these, use PakkISO. Using Monkey's Audio to decode the ape files sometimes result in files that don't match redump's md5 sum.

Mednafen memory cards[edit]

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[edit]

Blurry PS2[edit]

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[edit]

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.

PSP emulators[edit]

PSP audio[edit]

PSP emulation has no audio.
