+
+the Sound Creative Chip (SCC) adds 5 channels of wavetable to your MSX!
+it was used in (of course) several Konami games, which had better audio quality due to the extra channels provided by this chip (poor AY since nobody used the envelope for bass).

+a cost-reduced version of the YM2151 (OPM).
+it only has 3 FM channels instead of 8 and removes stereo, the LFO and DT2 (coarse detune).
+
+however it does contain an AY/SSG part which provides 3 channels of square wave with noise and envelope.

+this chip was used in the NEC PC-88/PC-98 series of computers, the Fujitsu FM-7AV and in some arcade boards.

+	Konami SCC emulation core
+
+	Konami SCC means "Sound Creative Chip", it's actually MSX MegaROM/RAM Mapper with 5 channel Wavetable sound generator.
+
+	It was first appeared at 1987, F-1 Spirit and Nemesis 2/Gradius 2 for MSX. then several MSX cartridges used that until 1990, Metal Gear 2: Solid Snake.
+	Even after MSX is discontinued, it was still used at some low-end arcade and amusement hardwares.
+	and some Third-party MSX utilities still support this due to its market shares.
+
+	There's 2 SCC types:
+
+	K051649 (or simply known as SCC)
+	This chip is used for MSX MegaROM Mapper, some arcade machines.
+	Channel 4 and 5 must be share waveform, other channels has its own waveforms.
+
+	K052539 (also known as SCC+)
+	This chip is used for MSX MegaRAM Mapper (Konami Sound Cartridges for Snatcher/SD Snatcher).
+	All channels can be has its own waveforms, and also has backward compatibility mode with K051649.
+
