SCC
SCC (Sound Custom
Chip or Sound Creative
Chip) is a sound chip developed
by Konami and Yamaha under the technical name K051649.
SCC is a primitive 8bit wavetable sound chip. It
adds 5 channels to the 3 PSG channels to produce
a better sound. The SCC chip has also his own
memory mapper. Each channel can be controlled by
an on/off bit, volume, frequency and 32 bytes
waveform.
SCC-I is a improved version under the form of a
Sound Cartridge released with the SD-Snatcher and
Snatcher games.
Differences between SCC and SCC-I are mainly an
independant 5th sound channel and an intern 64 Kb
RAM in SCC-I. This RAM can be expanded to 128 Kb.
To hear SCC or SCC-I, the SCC or SCC-I chip must
be present on a slot cartridge. It's the case
with the concerned Konami rom games.
Some games on disk (Konami Games Collection,
Snatcher, SD-Snatcher, adapted rom games for
Flashrom) or demos (Fony Demo Disk 1 for example)
require the insertion of a SCC cartridge or a SCC-I
cartridge to get good sounds. You can use for
that the File/Cartridge/Insert Special menu.
In other cases, you need to pause the emulator to
insert a real SCC cartridge just after the
booting.
There's no specific MSX-BASIC command for SCC.
Stereo
As SCC is combined is PSG, it gives a stereo
effect, that you can enhance by a fine tuning in
the mixer
Hear only SCC
- de-select the other soundchips in the mixer
Normal versions of these games
include the SCC chip and have the KonamiSCC (konami5)
mapper.
If you use a Flashrom version (ASCII8 mapper),
you must add a SCC chip in slot 2 by using the
special cartridge menu.
