No, that's not a stupid question at all (got to make sure you've covered all the options as it's often the simple things you overlook!) but I've got loads of space. I've tried it several times using different version of CHDMAN and the size and checksum are reported correctly but it just doesn't seem to extract back out quite the same as all the other Naomi games do. Since it doesn't get past the test menu in MAME it's hard to tell if the CHD is faulty in any way. It just seems odd that it's the only game I can't extract the disc image from properly.

Here's my output from CHDMAN:

And then I'd normally create a .cue file

FILE "gdl-0025.bin" BINARY
TRACK 03 MODE1/2352
INDEX 01 10:00:00

then launch ISObuster and extract the main game.bin out. But ISObuster can't find any data and, like I said, the actual size of the extracted disc image seems small when compared with all the other Naomi games I've tried (and I've tried a fair few).

I'm not saying for certain that it's faulty but I didn't know whether there was a bug in CHDMAN or the CHD itself that's not been noticed before since it's not playable in MAME..... or whether I'm missing something really obvious!?
