A few days ago I extracted the BGM videos from 'DJ Max Portable CE/BS/3' to convert to AVIs but I had the same problem with getting the sound from the PMF file, here is what I did:
First, Download 'AT3 Converter v1.3' for 6.20 PRO:
http://www.mediafire.com/?swccvoctxy3t53c
This should work on other custom firmwares too, but I have only tested it on 6.20 PRO-B7.
1. Download 'AT3 converter v1.3' and extract it to a folder on your computer.
2. Copy 'AT3Converterv13' folder into 'ms0:\PSP\GAME\' folder on memory stick.
3. Get the PMF video file or at3 music file you want the sound from and copy it into 'ms0:\PSP\Music\' folder.
- You can copy as many files as you like as the converter program will convert all files it finds.
- Program can decode and convert both AT3 and AT3Plus music files and also the sound from most PMF video files.
- Program is unable to convert 'headerless AT3 files' (demuxed from PMF files, just use the actual PMF file instead)
- If you have music in the 'ms0:\PSP\Music' folder, I recommend to move it to the 'ms0:\Music\' folder instead.
4. Make sure you have a bit of free space on your memory stick as a 3 minute audio file when converted into WAV format will be around 30mb.
5. Start AT3 Converter on your PSP by going to Game > Memory Stick and selecting 'AT3 Converter ver1.3'.
You might want to set CPU speed to 333/166 using the VSHMenu (Game CPU Speed) before running the program as this will speed up conversion.
You might also want to plug in the wall charger when converting as it uses a lot of CPU and Battery power. (PSP may get a bit hot too)
6. On first screen the program will load a few files and then you will see the options screen. (see section below for details)
Change the options to your liking and then select 'Convert' (top option) and press O.
Program uses the 'Japanese style' buttons, so you need to press O to start and X to cancel.
When converting, press
/\ to skip a file or press 'X' to cancel conversion.
7. Copy the converted WAV file from ms0:\PSP\MUSIC folder to your computer.
8. Convert the WAV to MP3 or any other format you like or remux it into an AVI, etc
