This doesn't really surprise me, System 1-3.0 is the same way. The loop has to be native to the music file. With Little Vampire, because the music file was so old, I had to reprogram SysEng  itself to do the looping.

SoundEngine still exists, they just changed domains. They're at https://soundengine.jp/ now. Try that and see what happens. They don't seem to have many older versions if that proves necessary, but they might be out there somehow.

The wavLinker tool you're looking for in the Alicesoft SDK is called NL5. I can't give you an exact file path because of the way English Windows unzips Unicode file names into ground beef, but searching the SDK for "NL5" will get you the program just fine.

Also, since the MG version of SR updated the files from WAV to OGG, it's likely that whatever metadata they're using to loop the file is relatively modern. I'm not all that familiar with audio but someone who is could probably tell you more.
