Reference: https://github.com/mamedev/mame/blob/master/src/devices/sound/namco.cpp
genpeitd (Namco C30) has RAM waveform held @ 0x400 (':cpu1'). It looks different from previous namco game boards. (formerly wavedata was expressed as a chunk of /0[0-9A-F]{32}/ or "use full byte, first 4 high bits, then low 4 bits")
genpeitd(源平) Namco CUS30/:namco/0/m_wavdata
0x100 ~ 0x13C, Changes as sound is played
0x2X9 ~ 0x307, Changes as sound is played
address: 0x308~ -> Speed of PSG playback of a certain sound code(Starting from PSG #01. for example, #05 is at 0x30D). -> Normal speed. Increase the value to slow the playback speed.
genpeitd has RAM waveform held @ 0x4000 (':cpu1'). but it looks different from previous namco game boards. Probably waveform #0 is:

You can see values below the waveform constantly changing as sound is being played.
:namco/0/m_voices
The number of voices to be used (default : 8). Set 1 to play just one voice, for example.
