Rockbox Replacement MP3 Player Firmware Gets Updated Remember Rockbox? Back when MP3 players couldn't do a whole lot more than play MP3s, Rockbox was there to add Gameboy emulators , additional codecs and other homebrew features. And if you're still holding on to an older player, the new version 3.0 now supports a whole lot more of them for squeezing a few more months of life out before you cave. It also now comes with a handy bundled installer. Thrift on. [Rockbox via Lifehacker ]
