So yeah, there's this game known as "osu!stream" which has recently been released on the iOS platform, it contains compressed beatmap archives (containing the audio for the song and graphics), I've had no luck with decompressing them myself and was wondering if any of you guys would be able to have a look. :3

Here is a sample file:
