Hi, I have an old 3DS (firmware version: 11.6.0-39U) and I tried to run Soundhax. But in the moment that I tried to playback the audio file in the sound app the console said that it wasn't able to reproduce the file, and instead of the homebrew, I got the normal music reproduction screen. I don't know what happened and I'm almost sure that all the needed files are in the SD card, and they match the firmware version. HELP!
