Here is a simple guide for the steps one should take to try to resolve your problems.

Steps to take

Update to latest version

Emulators can have stable builds that are weeks, months, and sometimes even years old. The "stable" version is often times just a randomly picked dev version. That is why the latest dev versions should be preferred. This could solve emulation issues most of the time. Links to dev builds can be found at the pages for PCSX-R, PCSX2, Dolphin, nullDC, DeSmuME and PPSSPP.

Change Settings

If you're using a plugin based emulator, graphical glitches and sound issues might be solved by changing the settings.

Check for known issues

There are resources available for emulators which lists the common known issues with games, and the solutions.

Check the archives

Sometimes, questions may have been asked and answered multiple times in the past. Check the Emulation General archives.

Ask Emulation General

If you still can't find a solution, ask Emulation General. Provide relevant details such as:

  • System specs, especially CPU
  • Emulator and version
  • Emulator settings/plugins
  • Game details
  • The problem itself. Do not forget that, because if you do then what comes out makes no sense whatsoever.

Common Questions

New systems emulated

Q: Is there an emulator for the 3DS, VITA, PS3, Xbox360, Wii U, PS4, Xbox one?



Q: Can I run [insert emulator here]?

See: Computer specs

Blurry PS2

Q: Why is my PS2 game blurry?

A: 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.

ECM format

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

A: 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.

Keybinds in lilypad

Q: I use PCSX-R with LilyPad, but the esc key and various others don't work!

A: In the keyboard Input API (radio buttons in the top left of the LilyPad options), choose raw input.


Q: I downloaded a file in a zip/rar/7z format, and inside it are a lot of files labelled either r00/r01 etc, part1/part2 etc or 001/002 etc files. What are these?

A: It's a split archive, usually RAR. Make sure you have 7-Zip installed. Do not use WinRAR. Extract all those files somewhere. Then, right click on the first in the sequence (e.g. r00/part1/etc) and, depending on the program used, should have an "Extract Here" command. Use it; it'll output the files you're looking for. You can then proceed to delete all those r0x/partx/etc files if you want.

PS3 controller

Q: How do I connect my PS3 controller to my computer?

A: Use XInput Wrapper SCP.

Save states

Q: My save states do not work in the new version of the emulator I downloaded. Why?

A: 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.

Mednafen save states

Q: Save states do not work in Mednafen PSX.

A: 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

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

A: You need to create/run the cue sheet (.cue). Support for multi-track games can be found in Mednafen, RetroArch, and PCSX-R. ePSXe does not support such features and should not be used.

PSP audio

PSP emulation has no audio.


Retroarch crashes

32 bit version crashes. It's a known problem. Download an updated build:


Help, I've downloaded a file and I don't know what it is?/What's the difference between these files?

Check out the List of filetypes for information on what's what, and where to use it.

Mednafen memory cards

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.

Using RetroArch#Transfer_PS1_Memory_Card_Files

Specific games

Dangan Ronpa

Make sure you're using the latest dev build of PPSSPP ((v0.8.1-664 onwards) .
Go to Settings > Graphics > Under "Buffered Rendering" activate "Read Framebuffer to Memory (CPU)" If you have an AMD Graphic Card or Android Device. If you have Nvidia, activate "Read Framebuffer to Memory(GPU)".

Metal Gear Solid

A: MGS has anti-piracy features, and needs real bios to work. Do not use simulated bios in PCSX-R. These will just give a blank screen. If you are using bios and it still is not working, try different bios files. And that the BIOS is selected under the Plugins and Bios configuration menu.


Most people try to use VBA-M. Stop that. That is geared for GBA emulation. Use Gambatte.

Metal Gear Solid 3

This game needs a very high end CPU to run at full speed and will run slowly on most CPUs.  All of the various blades of grass are one culprit cause of slowdown.

Shadow of the Colossus.

This game needs a very high end CPU to run at full speed.

Zone of the Enders 1 and 2

This game needs a very high end CPU to run at full speed.
