CHD - Uncorrectable data #91

Closed dvessel closed 6 years ago

dvessel commented 6 years ago

CHD files are unreadable. When pressing run to load the CD a notification stating "Uncorrectable data at sector xxxx" where xxxx is the start of the data track.

Decompressing the CHD file will allow it to play and the beetle-supergrafx-libretro core plays the CHD without problems.

Can you tell me if this started happening recently? Did this ever work for you before?

Can you poinpoint to a version where it was still working if so? Note - I need an exact Git revision, being told 'it worked on that day or whatever or within that month' will not be helpful. It would be extremely helpful if you could compile from source and do the necessary bisecting in such a scenario.

I ask because the libchdr code has recently been updated in these cores, and to avoid a scenario where the libchdr code is wildly out of lockstep with the rest of RetroArch, we need to make sure that this time people can stay on the same page. That did not happen before and that is what is leading to huge issues.

To all bystanders - libretro-common code should NOT be modified, it should be used verbatim, else we run into all sorts of issues with statically linked targets. Libretro-common code should be used verbatim as what is on the RetroArch/libretro-common repos.

It stopped working after updating the core this morning. I dug into my backups and the most recent version I have that works is from 2 days ago, April 21st.

Sorry, I'm not sure of the exact git version and I don't know how to compile from source.

That sucks, and was exactly what I did not want to hear.

I was getting crashes with Mednafen Saturn core too but it looks like all the CHD changes were reverted and all is well right now. Closing and Thank you for all the amazing work.
