I want to make my own music mod, so I tried using the software known as Goldwave
Atrac3 codec to make a wav with Atrac3 attributes file
GWAT3 to change the extension into .at3 in order to use it for making my own music mod
using this method
or using UMDGen
but when I try save the mp3 file in the .wav format, I don't see the Atrac3 attributes, I installed the atrac3 driver, restarted my computer then installed GoldWave, it still didn't work, I then tried it the other way around and it still didn't show. What should I do to solve this problem?
