I can confirm the fix works, although the build I used failed to play the FMV at the end of each episode, so it wasn't ideal.

edit: The build in question was EmuCR's DOSBox SVN r3711, and I've just checked again with their latest r3727 with the same result.

edit2: Sorry, I messed up there. That build plays the MIDI music, and I somehow didn't notice. I have now used a build which both loops the CD audio and plays the FMV. I'll add a URL later if the author approves.

Cross-referencing with the following post, because this issue becomes REALLY apparent once the .ogg files are looping.

In short, nearly all of the CD audio tracks (which are encoded as .ogg files in the GOG version of the game) have incorrect start and end points. The first second of so of each track is actually at the end of the previous track.

Oh, good I'm not the only one. It seems that the two latest EmuCR builds (r3727 & r3728) are not mounting the cue sheet correctly (game.inst). Mounting the cue sheet seems to work fine in 0.74. I tried renaming it as an actual cue file, but it had the same result.

The emucr builds don't support ogg for audio tracks. hence the mounting fails.

Good to know. So do they need to be wav, mp3 or maybe flac?

I never tried that build as I use my own builds that do support ogg.

For the emucr builds:
wav might work. doubt others will

I'll get you a build that should work

Here is a custom DOSBox build to improve the support for Blood which includes the fix for this bug.

Lovely! Thank you both.
