I just got a new battery and screen for my Darth Vader PSP2000 just to play this but have been struggling because the audio is so terrible which makes it difficult to hear the beat over the other sound effects. I had to try three different pairs of modern headphones to find one that even worked and yet the audio is still so hard to hear. IIRC the original earbud that came with it was a mono piece (just one ear) so maybe I need to buy an amp or something. Or perhaps its the 30 years of hearing abuse I’ve subjected myself to in the interim that is the culprit.
