Lisa's Sound Driver (LSD) is a Sega Mega Drive sound driver developed by Lisa Ching for Tengen. Based on Atari's RPM sound driver (notable for its use in the company's early arcade games[1]), Ching ported the driver to the Mega Drive for use in Tengen's home console games.[2] Due to the similarities between the YM2612 and YM2151 sound chips, the driver is able to output admirable reproductions of the original arcade hardware.
