I have successfully de-CQM'd a CT3990 and CT3600 :
I also took a look at the CQM chip and it runs off 46.615120MHz, with 20x cycles per BCLK and 960 cycles per sample, giving 48557.416...Hz sample rate. Output format is 16bit i2s with 48x BCLK cycles per sample. Original OPL2/3 sample rate is 3.579545 / 72 = 49715.903...Hz.
YMF289 has 16bit Right-Justified format so no reuse of the TDA1387 DAC is possible, one will have to use the crappy Yamaha's DAC.
