Yeah, this was after i made megadrive/sms use the new sn psg device. The old device didn't boot out with callers of different subdevices using the same code (eg. SN76489A and SEGAPSG). Regression was posted by Firewave on the mailinglist a few weeks ago IIRC. The sound works fine on a not-debug build btw.
