PCM music
Within the ISO image of this prototype are some specific files, preceded with the letters "SNCBNK", with a number afterwards. The numbers refer to the Round and the letters refer to the time period for which the file represented. For example, "SNCBNK1A" represents Palmtree Panic in the Present.
Each file is a small music loop, played using the PCM chip of the Sega Mega-CD, according to the Round and time zone it represents. Speculation has been rampant as to their use, but two theories have stemmed that seem to be relatively plausible:
- They were intended to be used to bridge the inevitable gap created when a looping CD audio track rewinds to start again.
- They were intended to be played at the start of a level, before the CD audio played.
The 2011 Sonic CD re-release uses them for loops, so it is highly probable that was what Sega intended to do for the Mega-CD version.
These files are available here (info) (1.97 MB), courtesy of ICEknight. Edited files merged with the CD audio tracks by Shadow Hog are available here (info) (33.56 MB). Discussion of this oddity was held in
