Crashing when scanning certain Japanese CD-ROMs

[gingerbeardman]

Hi,

I have a lot of old Japanese CD-ROM MACLIFE from 1997 to 1999.

I use DiskTracker 2.02 to catalogue the contents.

With two specific discs, the scan results in a hard crash of BasiliskII. With all the previous discs, scanning works without issue.

How can I see if this is an emulator problem (my hunch) or an app problem?

I have given a lot of memory to BasiliskII (from 32MB up to 128MB) and to the app (from 4MB up to 64MB).

I'm happy to provide one or both CD-ROM ISO if they would be helpful.

I'll check with the debugger, so please provide the ISO files. Also, please tell me the operation procedure of DiskTracker that causes a crash.

DiskTracker 2.02

1. File > New Catalog
2. Scan > Scan Mounted Volume
3. Choose "CD-ROM MACLIFE 130" > Scan
4. Scan begins (Hard Crash)

An unrecoverable SEGV occurred while scanning MACLIFE130. However, SheepShaver was able to scan successfully. There is a alternative, so I won't investigate further.

Thanks, I don't know this type of error. It is an emulation-level problem?

I'll use SheepShaver to finish the cataloguing. Cheers!

The long name of SEGV is "Segmentation fault".

In this issue, the actual 68k Mac may also behave in the same way, or the BasiliskII emulation may be incomplete.

Thanks, I finished the cataloguing using SheepShaver. 😎
