NEO-YSA



NEO-YSA is a chip that was used in the NeoGeo CD since the CDM4-1 version. It regroups the YM2610, NEO-VOC and NEO-SUD chips. The output is compatible with the LC78815 DAC and therefor does not need the YM3016. Future versions of the hardware didn't contain any Yamaha branded chips.

Another revision, NEO-YSA2 is included in the CDZ and ROM-only arcade boards.
