Actually, you should wait for the next build, we're all in for a big treat!
NukeYKT has fixed all the bugs and added accurate DAC quantization and "Ladder Effect" emulation to his cores.
Basically, it is the first OPN2 emulation that sounds exactly like the hardware including all the noise and distortion of the YM2612 DAC.
"DAC quantization" option applies only to the Mame core, Nuked cores have everything already included.
He included three new options for the Nuked-OPN2 varitions:
2. Asic YM3438
3. Discrete YM3438
Here are some examples where there is clear difference.
In the archive I included my Model1 VA6 recording and all new OPN2 core variants.
The clips have been professionally recorded and normalized to be same volume.
Aladdin: listen for intro noise and 16sec note stops tail quantization.
Konami Logo: listen for music end tail quantization noise.
