Summary	09070: cdiscon1: Missing low-pass filter on some channels
Description	The standalone board ROM (disco) uses a low-pass filter for the BGM's bassline, which should be present in the DECO Cassette version as well, as indicated by this video. I can tell it's the cassette version because it uses a slightly different tile for the border. https://www.youtube.com/shorts/cFQQHGf-jNU
