Runner2 .celt file by puggsoy at 4:42 PM EST on February 4, 2015
I'm trying to extract audio from the game "BIT.TRIP Presents... Runner2: Future Legend of Rhythm Alien". This contains FSB files, which I managed to extract using FSB Extractor. The resulting file is a .celt file, and although it appears to have a valid WAVE header, the format value is 0x674F. Pretty weird. Here's a download.
