Distorted sound in FX-Unit Yuki

07 May 2018, 03:49

The audio is screwed up when playing FX-Unit Yuki on the SSDS3. This is a v2 unit hooked up to a SuperGrafx with a PackAPunch MD2 SCART cable. I received the game this week and ripped it using TurboRip 1.40.

The music sounds blown out. It does not exhibit this issue on a real CD setup.

I'll have to order a copy to try. Meanwhile, can you paste a few lines of the cuesheet? For 3 or 4 tracks is enough, I want to check something. Maybe the cdrom audio tracks are recorded with pre-emphasis, that sounds distorted is de-enphasis is not applied when playing back (which ssds3 is not doing)

EDIT: I've tried the demo and I can't notice distorted sounds.

The new firmware has a volume adjustment option so it can be adjusted to avoid clipping the audio output. It was set to 100% but it seems some games are too loud and they cause distortion when the sound is added to the PCE output.

Cool! If you give me the beta firmware, I can do a capture on a three way test against:

* TurboDuo
* Current firmware
* Beta firmware on several volume settings

I tested the game on my ssds3 and my ifu and it is heavily clipping on both. The music is definitely mastered to hell and back. It might be more obvious on the ssds3.

I will check the CDA on my DAW and report back.

Yeah, I've noticed the same issue with Yuki and my SSD3. The CD plays just fine on my Duo.
