ym2413+ay8910 to ym2608, PSG detuning occurs

3

I first converted ym2413+ay8910 to ym2413+ym2608.ssg, and then converted it to ym2608.fm+ym2608.ssg. At this time, I found that ssg was two tones lower. If I convert ay8910 to ym2608.ssg first,...

I wish I could specify stereo when converting the default mono like PSG/OPLL, like putting channel 1 on the right.

OPL1+OPL2 (or OPL1+OPLL ) to OPL3

There are a lot of music using MSX-Audio using the strange combination of Y8950+YM2413, and the number of such tracks is not small, because the MoonBlaster driver uses such a...

There are many ZX-Spectrum using PT3 to drive AY8910, these music use the hardware envelope function of AY8910 to change the waveform of a channel. These bass waveforms are completely...

There are some MSX tracks that use the FM part of the OPL4, I recorded such music as VGM, and found that most OPL3 players using hardware don't allow direct...

Convert OPN to OPL series, lose FM3ex extra channel

1

There are many OPNs that use FM3ex channels. The third channel of FM is split into multiple channels for use. I hope this feature can be handled correctly.

Currently I want the full support of NGP, which involves dual chips.

NGP to AY8910 noise frequency conversion error

4

  The NGP noise frequency seems to be a little different from the normal SN76489.

I have a hardware SN76489 VGM player. For NGP's VGM, it cannot play normally, because there are many differences between NGP and SN76489, although both are DCSG.

After YM2612 VGM made by deflemask is converted to YM2413 (FMPCM), PCM is lost
