Method for PSP to play atrac3 plus

A few days ago, though it was outdated, the sound was really good, and it worked better than anything that could sound in my house. Including my 6-Year-Old Panasonic ct800,

Half of them are due to the excellent quality of atrac3, so today I took out my little P and added it to my workshop. After all, this is also a thing that supports atrac3. I found that many online buddies are still depressed. How can I use PSP to listen to atrac3. Many methods are also cumbersome. By the way, I will introduce my methods. We hope that people who have difficulties can Google it here:
1. Install SonicStage 4.3 Chinese version. You can go down to over 90 m online.

2. Use SonicStage 4.3 to convert a CD or wave file (ape can use Nero's image recoder to a CD image and hook it up with a virtual optical drive) into the atrac3 plus format. Note: Do not use atrac3 advance losseless. PSP is not supported.

3. Copy the converted. oma file to the music directory of the memory stick. Change all. oma extension names to. aa3. A small P can be played.
