Ymf288 Ultima (SSG) by vintage micro media published on 2015-05-25T13:07:58Z Another simple test of the PSG part of the YMF288. I have changed the audio-connections a bit to allow better stereo effects when the FM-channels are used. There are audible clicks which come from the activation of the relative select lines of the chips. Some capacitors and better separation of analog and digital mass will solve this problem in the final design. Genre ymf288
