Turns out it might be audio data bring transferred to the sound chip, though with that chintzy MIDI BGM and wimpy SFX I'm not sure it's worth the wait. At least we get character voices.There's probably some sort of timing built into the game in waiting for it, unfixable I imagine. What's also bad is how the audio cuts out as soon as the round winning attack lands, voice samples etc all stop. It's an impressive version of it spoiled by really small presentation issues.
