How to Open a BIN File Without a CUE File

You have a disc image ending in .bin. You try to mount it or load it in an emulator, and it fails. The program wants a .cue file, and you do not have one.

This is one of the most common disc image problems. The CUE file is tiny and easy to lose, especially when files get copied around or downloaded one by one. The fix is quick. You can open a BIN file without a CUE file by making a new CUE in seconds, or by using a program that does not need one.

What is a CUE file and why do you need it?

A CUE file is a small text file. It is usually less than one kilobyte. It describes how the data in the BIN file is laid out.

A CD can hold more than one track. A game disc might have one data track and ten music tracks. A music CD has many audio tracks. The BIN file stores all of these back to back as raw data. Without the CUE file, a program cannot tell where one track ends and the next begins. It also cannot tell whether a track is data or audio.

A simple CUE file looks like this:

FILE "game.bin" BINARY
  TRACK 01 MODE1/2352
    INDEX 01 00:00:00

That says: read the file game.bin, it has one track, the track is data stored in 2352-byte sectors, and it starts at the very beginning.

Method 1: Generate a CUE file with our tool (fastest)

For most single-track discs, this takes under a minute.

1. Open our free BIN file opener in any browser.
2. Drop your .bin file in. It is read on your device, not uploaded.
3. Check the type. It should say “Raw CD image” or “Likely raw CD image”.
4. Open the “Convert & save” tab and click “Download .cue”.
5. Save the .cue file in the same folder as the .bin file.
6. Make sure both files have the same name, like game.bin and game.cue.

The tool reads the sector header to pick the right mode. MODE1 is used by most PC discs. MODE2 is used by PlayStation and some other consoles. It also writes the exact BIN file name into the CUE, so they match.

Now mount the .cue or load it in your emulator. It should work.

Method 2: Write a CUE file by hand

You can also make one yourself in any text editor. This is useful if you want full control.

1. Open Notepad on Windows or TextEdit on Mac. In TextEdit, choose Format, then “Make Plain Text”.
2. Type these three lines, using your real file name:
   FILE "yourfile.bin" BINARY
  TRACK 01 MODE1/2352
    INDEX 01 00:00:00
3. Save it as yourfile.cue in the same folder. In Notepad, set “Save as type” to “All files” so it does not become yourfile.cue.txt.

If the disc is from a PlayStation, change MODE1 to MODE2. If you are not sure, use our tool. It checks the sector header for you.

Which mode should I use?

The mode tells the program how each sector is built. Using the wrong one is the main reason a hand-made CUE fails.

• MODE1/2352 is for most PC CD-ROMs and Sega Saturn and Sega CD discs.
• MODE2/2352 is for PlayStation 1 discs, Video CDs and some others.
• MODE1/2048 is for images with only the user data, like ISO files renamed to .bin. In this case the file size divides evenly by 2048 but not by 2352.
• AUDIO is for music tracks.

A quick tip: if the file size divides exactly by 2352, it is a raw image. If it only divides by 2048, it is really an ISO with a .bin name. You can rename it to .iso and mount it directly. Our BIN vs ISO guide explains why.

What about discs with music tracks?

Some games and all music CDs have audio tracks. If the BIN holds several tracks, a basic one-track CUE will load the data track but the music may be missing or wrong.

To fix this, you need the start time of each track. If you still have the original disc, rip it again with a tool that writes a full CUE sheet. If you do not, look for the correct CUE online. Many game preservation databases publish exact CUE sheets for known discs. Make sure you match the exact version and region of your disc.

A multi-track CUE looks like this:

FILE "game.bin" BINARY
  TRACK 01 MODE2/2352
    INDEX 01 00:00:00
  TRACK 02 AUDIO
    INDEX 00 45:12:30
    INDEX 01 45:14:30

The times are in minutes, seconds and frames. There are 75 frames per second on a CD.

Method 3: Open the BIN without any CUE

Some tools can read a BIN directly. This works best for single-track data discs.

• Archive tools. 7-Zip can open many single-track data images and let you copy files out. See our BIN file extractor guide.
• Some emulators. A few emulators accept a bare .bin for single-track games. Check your emulator’s notes.
• Converters. Converting the BIN to ISO removes the need for a CUE for data discs. Read BIN to ISO.

Troubleshooting

“File not found” when loading the CUE

The name inside the CUE does not match the real BIN name. Open the CUE in a text editor and fix the name after FILE. It must match exactly, including capital letters on some systems.

The game loads but has no music

The disc has audio tracks that your CUE does not describe. You need the full multi-track CUE.

The game crashes or shows “disc error”

Try the other mode. Swap MODE1 for MODE2 or the other way around. If our tool made the CUE, it should already be right.

I have several .bin files for one game

Some rips save each track as its own BIN, like “Track 01.bin” and “Track 02.bin”. You need one FILE line for each, in order. Keep all files in one folder.

The CUE saved as .cue.txt

Windows hid the real extension. Turn on file name extensions in File Explorer and rename it.

How to avoid losing CUE files

• Keep each game or disc in its own folder.
• Zip the BIN and CUE together before moving or backing them up.
• Name both files the same.
• Do not rename the BIN without updating the name inside the CUE.

A quick example

Ali finds an old PlayStation game backup on a USB stick. There is a file called “racing.bin”, 520 MB, but no CUE. His emulator will not load it.

He opens the BIN in our tool. It says “Raw CD image” and the first bytes show the CD sync pattern. He downloads a CUE from “Convert & save”. The tool picks MODE2/2352 because the sector header says mode 2. He saves racing.cue next to racing.bin and loads it in the emulator. The game boots on the first try.

How to check if your BIN is a raw image or an ISO in disguise

This one check saves a lot of time. Right-click the BIN and look at its exact size in bytes. On Windows, open Properties. On Mac, choose Get Info.

Now divide the size by 2352. If you get a whole number with nothing left over, the file is a raw image. It needs a CUE file with a 2352 mode. If it does not divide evenly, divide by 2048 instead. If that gives a whole number, the file is really an ISO. Just rename it from .bin to .iso and mount it like any ISO.

Our tool does this math for you. If the size is an exact multiple of 2352 and there is no sync pattern, it says “Likely raw CD image”. If it finds the ISO marker, it says “ISO disc image”.

Why CUE files get lost so often

CUE files are small, so people forget them. Download sites sometimes list them as a separate link. Cloud storage apps may skip files they do not recognize. Some antivirus tools flag unknown text files. And when people rename a BIN to tidy up, the CUE inside still points to the old name. Knowing these traps helps you avoid them next time.

Frequently asked questions

Can I open a BIN file without a CUE file?

Sometimes. Single-track data discs can be opened by archive tools or converted to ISO. For games and multi-track discs, it is easier to make a new CUE.

Is it safe to use a generated CUE file?

Yes. A CUE is just plain text. It only tells programs how to read the BIN.

Does the CUE file name matter?

The CUE can have any name, but matching the BIN name keeps things tidy. What really matters is the BIN name written inside the CUE.

Where do I find the right CUE for a multi-track game?

Game preservation databases list exact track layouts for known discs. Match your disc’s exact title, version and region.

Conclusion

A missing CUE file is a small problem with a fast fix. For most discs, a three-line CUE is all you need, and our free BIN file opener makes one in a click. For discs with music, find the full track list. Then mount the image or load it in your emulator as normal. Want to mount it on Windows? Read how to mount a BIN file.
