Look at the Roll-Up Pack thread in this subforum and read it carefully. Your answers are in there.
 
there is a mistake on the spreadsheet, dragon ball z is actually a cdrom and not a dvdrom, it has to be corrected, so you have to extract cd iso with CHDMAN

Well, it is a DVD (says MAME and the image below). If you were able to extract it from chd to an ISO using "extractcd" what happened next? Did you burn it to a CD? Did it run? My guess is that it might extract, but that's probably it. try extractraw and then burn it to a dvd...

If it does work I’ll provably want to repack the CHD and submit it to mame. Let me know if you can, or I’ll try in a couple days when I have some time.

I use extractraw to a .iso extension with dvd images, works great, unless I'm technically incorrect. Always can be wrong lol. But that's my process to test a backup dongle, which works fine.
 
worked for me as cd and not as dvd... has to retry to burn with slower speed

I checked the "db1.chd", it is in fact stored as a CD/ISO image -- "chdman info -i db1.chd"

Your photo raises a valid point, and in fact the MAME source does state it is a DVD, but the chd is packed as CD/ISO. I extracted the chd using both "extractcd" and "extractraw" and the result from extractcd is correct, a valid iso9660 image. Only 412mb of data.

@ekorz if you have an original disc, I send you software and instructions to make a correct dump of the disc for both mame and redump :)
 
@brizzo Unfortunately I don’t have an original. But couldn’t you extract the chd as a cd, write it to a disc, then extract that raw? I would think the result would be suitable for a dvd. Maybe I’ll try it tonight.

That would be the original data, just packed correctly.

Though the mame folks probably wouldn’t accept it. Last time I tried to suggest a change without owning an original I got shot down!

Anyway @archimage I can make a note on the spreadsheet in the meantime, thanks for your research! Maybe I’ll make a column with the actual chdman commands for folks to copy/paste.
 
Asked the Redump guys best way to determine disc type, they suggested using ImgBurn as it clearly tells you the type of disc currently in the drive :)

They said there are known instances of a CD having the DVD logo on it

How to make a disc image:

The preferred tool is to use DiscImageCreator -- http://www.mediafire.com/file/eq80y20l9cwf48f/DiscImageCreator_test.7z (More information here)

DiscImageCreator is ran from the command line, here are some examples:

Making DVD image:

DiscImageCreator dvd K: ZDX1 1

Making CD image:

DiscImageCreator cd K: NPY1 1

Explained:

First parameter is the disc type (cd or dvd), K: is the drive letter containing the disc, ZDX1/NPY1 is the name you decide for the image (I am using the code found on the disc and dongle), 1 is the read speed used

Extras:

It is also preferred if you can also scan both the front and back of the disc at 300 dpi :D
