I have these two files that I'm trying to export in order to import back another file, I send here two examples in order to see if is possible to manage an import and export.

YYZ file somehow is possible to open on audacity as a Raw file, Signed 16-bit PCM, Big-Endian, 1 channel Mono, 0 bytes, 100% of Quantity, 44100hz and then slow down the speed of the sound.

The XA file is not like the PS1 XA files, this XA is basically a stand alone file with one audio attached. Basically is a port to PC with some obfuscated attributes.

About this question I had it figured it out.
For the .xa files (This also applies for these PC games ports: Bugs Bunny Lost in Time/Bugs Bunny Taz Time Busters/Grinch/Jersey Devil) they are encoded in adpcm. In the attachment you will find the Encoder/Decoder. Just place the .xa files there and run the decode.bat to decode them to wav. To encode, place your wav files (Stereo, 44100Hz) and run the encode.bat


The YYZ files are just cryptographed AIFF sounds.
Use 010 editor to open the YYZ and then Binary Invert it, Signed Byte FF and save it. Now you have your AIFF file and you can open with audacity.

To convert back to a YYZ cryptographed file, go to Tools > Operations, Binary XOR, unsigned Byte, operand FF Hex.
