It's too bad those charts are apparently for songs by bands I don't like.
And didn't that Space Channel 5 Part 2 port come out ages ago? At any rate, if it's anything like the other Dreamcast-to-current-gen ports Sega did, the only change will be that it's upscaled to 720p (the only one that had other changes was Crazy Taxi, which had all the licensed music and real store names removed).
(Dark Souls is installing as I post this.)
