Custom Boot Tunes

Editing your memory stick can cause permanent errors. Always back up your memory stick before tampering with it.

Custom Boot Tunes[edit]

This page assumes that you have a basic understanding of how to read from and write to a memory stick.


  • SONY-brand memory stick reader
  • Audio editing program
  1. Many members of the community use the following website to convert .WAV files:
  2. Alternatively, Audacity is another option as a free audio editing program:

Note that regardless of the length of your file, once it completes, it will immediately loop until your AIBO is finished booting.


ERS-110 or ERS-111[edit]

For the ERS-110 or ERS-111, in order for a boot tune to be valid, it must meet the following requirements:

  • .WAV file
  • Mono
  • 16bit
  • 32000hz
  • Short enough to fit on the memory stick.

(Side note: 11x dogs are known to be unstable with boot tunes and it may not always work.)

ERS-210, ERS-220, or ERS-31x[edit]

  • .WAV file
  • Mono
  • 8bit
  • 8000hz
  • Short enough to fit on the memory stick (usually between 1 and 45 seconds).


  • .WAV file
  • Mono
  • 16bit
  • 16000hz
  • Short enough to fit on the memory stick (usually between 1 and 33 seconds).

Replacing the Old Boot Tune[edit]

Once you have an audio file of the boot tune you want that meets these requirements, name it BOOT.WAV (or, if it is for an ERS-7, BOOT16.WAV) and place it in the following location on the memory stick:


Either remove the previously existing BOOT.WAV/BOOT16.WAV before placing the new one in the folder, or overwrite it.

If you were successful, when you try to boot your AIBO with the new BOOT.WAV, you should hear your customized boot tune. If your AIBO remains silent for the entirety of booting, the boot tune you have given it is invalid - double-check that the file you made meets the requirements above. If your AIBO plays an error tone, you may have put the file in the wrong place or otherwise modified the memory stick incorrectly.
