No.18481 Tafoid Administrator Feb 24, 2021, 16:45	Is this addressed in 07856?
No.18488 windyfairy Tester Feb 26, 2021, 08:12	Reproducible even with my previous fix for 07856. I think a redump of the dstage program CD (gc845eba.chd) may be required. ddru uses the same opening as dstage and it works fine in ddru.
No.18489 windyfairy Tester Feb 26, 2021, 08:21	Further research: dstagea also works. dstagea and ddru both have subcode data but dstage does not. I strongly suspect it's just a bad dump that's causing issues here.
No.18706 AriaOTP Tester 5 days ago edited on: 5 days ago	It's fixed on current git. I think https://github.com/mamedev/mame/pull/7878 merge finally fixes this issue. Works well on current chd.
