Certain CDs have file not found

[ualaa1]

What happened?

Games that seem affected so far:
Discworld II
City of Lost Children
Pinball World
Links LS 1997

I have tried with multiple dumps of the games, and it seems that for some reason 86-Box can't seem to find the files for these CDs. To reproduce these issues, mount the disks onto the D drive and try to look for files. On 86-Box, files don't seem to exist, but when testing them on Dosbox-X they were able to be found.

What CD-ROM driver are you using in DOS?

[OBattler]

I can't reproduce this at all, so it must be the DOS CD-ROM driver you're using.

[ualaa1]

I uploaded the VM, NVR, and config files on here: https://file.io/Decqtu3xGN1A

[OBattler]

It appears you're using GSCDROM.SYS. What CD-ROM driver are you using on DOSBox-X?

[OBattler]

So, the same GSCDROM.SYS reads a Mode 1 CD fine. So it turns out the driver does not support Mode 2 data. I recommend using VIDE-CDD version 2.15 instead.

[OBattler]

This is VIDE-CDD version 2.15: VIDE-CDD.zip .

[OBattler]

So I'm closing this with NOTABUG on our side - use the driver I just linked.
