MAMEWorld Forums - EmuChat - Laserdisc chd problems?

Hello,

What sorcery is needed to get a laserdisc game like firefox to run?

I have a chd for it and get a "decompression error"

I see this when I run chdman -info

Code:

              ............................................................

which seems right? But I get that decompression error.

So I used "chdman verify" and it was happy.
And then "chdman copy" and received a new different chd that gives me the same error.
So I tried "chdman copy --compression none" and got a 40GB chd. And now mame says that it must be compressed with avhuff or whatever.

So I tried a few older mame versions lying around from last year + one of haze's builds to see if it was my compiles. But they all do the same.

Any ideas?
