 Given the large number of FMV games and Genesis ports , the Sega CD 's game library has been criticized for its lack of depth . Full motion video quality was substandard on the Sega CD due to poor video compression software and the system 's limited color palette , and the concept never caught on with the public . According to Digital Pictures founder Tom Zito , " Sega CD could only put up 32 colors at a time , so you had this horrible grainy look to the images , " though the system was able to put up 64 colors at one time . Likewise , most Genesis ports for the Sega CD featured additional full motion video sequences , extra levels , and enhanced audio , but were otherwise identical to their Genesis release . The video quality in these sequences has also been criticized as comparable to an old VHS tape .
