The MEGA65 comes with 4 integrated FPGA SID chips. In this episode of the MEGA65 Podcast is a demonstration of how each of them sounds. Note that SID 1 is ca. 70% right, not located in the stereo middle, and there also is headroom for the other SIDs plus the 4 DACs (and future OPL2) – so you might want to turn up the volume. This is a digital recording and does not resemble the dynamic range of the analog audio jack.
