Hi all,
I'm trying to play the PC Engine version of Ys IV (The Dawn of Ys) with the English translation and English dub patches in BizHawk, but it's throwing an error when I try to run it:
A core accepted the rom, but threw an exception while loading it:
System.InvalidOperationException: Unsupported scenario: reading 2048 bytes from an unhandled sector type
at BizHawk.Emulation.DiscSystem.DiscSectorReader.ReadLBA_2048(Int32 lba, Byte[] buffer, Int32 offset)
at BizHawk.Emulation.DiscSystem.DiscIdentifier.StringAt(String s, Int32 n, Int32 lba)
at BizHawk.Emulation.DiscSystem.DiscIdentifier.DetectDiscType()
at BizHawk.BizHawk.Client.Common.RomLoader.LoadRom(String path, CoreComm nextComm, Boolean forceAccurateCore, Int32 recursiveCount)
I ripped the original disc (R1F version) myself using TurboRip, and both the original version and the version with the English text (not dub) patch run fine -- it's just after I apply the English dub patch that it throws this error. I'm not sure if the issue is with the patch or with BizHawk, but it runs in RetroArch okay. (I've tried both BizHawk 1.12.0 and a recent developer build.) It's not an end-of-the-world issue or anything, but any help with this would be appreciated! ^^
Just bumping this thread to post a solution, in case anyone else runs into this problem:
If your copy is in ISO/WAV/CUE form (which is what the dub patch is made for), replace the WAV file for track 1 with the equivalent file from the original Japanese version. I'm not sure why this particular track causes trouble, but since it's the "Don't put this data disc in your CD player!" track and not something that actually plays during the game, replacing it shouldn't break anything with the game proper.
I haven't played the dub patch all the way through to make sure it's 100% working, but the opening cutscene also plays audio from a track that was replaced in the dub patch and that works okay, I'm guessing this is the only file that makes BizHawk act up.
