All of the GX games should be marked GAME_IMPERFECT_SOUND as the TMS57002 has not been hooked up to process the output of the 054539s.

To be honest, every game using the 054539 should be marked as GAME_IMPERFECT_SOUND as the emulation is somewhat flawed (imperfect DPCM decoding, gain levels and reverb to name a few)

I have the original PCB, you need an original audio recording?
I also noticed poor sound in "Fantastic Journey". I have the original PCB "Gokujyou Parodius" and "Sexy Parodius".
