Just wondering if someone could clarify but is the following result normal behaviour?

To explain, I attempted to dump a redump-verified image to a single bin/cue file using DTLite/ImgBurn. I usually do this for checking for inconsistencies when converting NonRedump images to separate tracks (e.g. cloneCD, single bin files etc). I usually notice the above errors on multi-data tracks when incorrectly calculating pregaps/sectors lengths using isobuster. Assuming it is correct, would playback be an issue given all the errors ImgBurn is spewing out?

The above output was taken from https://redump.info/disc/17355/
(It's unlikely that 4 separate dumpers failed to correctly dump the said disc)

On a broader note, should redump images playback without issue on hardware capable of doing so?

track length is miscalculated and perfectrip throws an error because it detects different track modes in the second track. there might be audio silence in-between both data tracks as well.

Does this mean there could be a problem with the accuracy of the dump information currently in the database? Or is it a problem with ImgBurn in this instance?

To clarify, it's ImgBurn throwing out the said errors and not PerfectRip.

Thanks.

You won't be able to play PSX or Saturn dumps in unmodified hardware due to copy protection, but you can play burned discs in unmodified Mega/Sega CD (but only the same region of the hardware).

You can use CDMAGE to make multiple track images into a single image for burning.

However for discs with mastering inconsistencies you'll need the subs and a clonecd cue sheet to burn them properly.

CDMage's output matches the one obtained by copy /b "file1.bin"+"file2.bin"+"file3.bin" "Final file.bin", as expected.

That's not really what I'm getting at since I typically burn the images to disc without converting them as you suggest. There's no real reason to, is there?

However for discs with mastering inconsistencies you'll need the subs and a clonecd cue sheet to burn them properly.

Are such discs accurately identified in the redump db? I understand you can use sbi2sub with the provided .sbi attachments for libcrypt encrypted discs to generate the necessary subs for burning. Putting libcrypt aside for the moment, isn't it conceivable that some discs already in the database (e.g. Saturn and PSX) won't ever playback on real hardware? I must add that I've never had any problems on anything I've played to this point.

So what's going on with the dump I mentioned earlier? Is it a mastering inconsistency, a series of bad dumps, ImgBurn issue?
