On 9 September 2009, the Beatles' entire back catalogue was reissued following an extensive digital remastering process that lasted four years. Stereo editions of all twelve original UK studio albums, along with Magical Mystery Tour and the Past Masters compilation, were released on compact disc both individually and as a box set. A second collection, The Beatles in Mono, included remastered versions of every Beatles album released in true mono along with the original 1965 stereo mixes of Help! and Rubber Soul (both of which Martin had remixed for the 1987 editions). The Beatles: Rock Band, a music video game in the Rock Band series, was issued on the same day. In December 2009, the band's catalogue was officially released in FLAC and MP3 format in a limited edition of 30,000 USB flash drives.
