Look,it's a Wii U game. If it would be a Wii game maybe we could dig into the BRSAR. i am totally sure that SM3DW have both streamed music and sequenced. But i think no one figured out how to extract them...
It has both, yes. Extracting it isn’t exactly too difficult either. The issue is I’m not sure there if there are any BFSEQ to MIDI converters out there yet, but given how the format is similar to previous BRSEQ sequences, repurposing some converters out there for those might be relatively easy compared to reverse engineering BFSEQ from scratch.
