Instead of getting GDIs and then convert them yourself to CHD, you could just get the CHD instead (they're probably in the same place you get GDIs).

This is also a good option, but he is reluctant to repeat the downloading process. It will depend on what OP is willing to invest his time in haha.

This is going from my memory more than 20 years ago but should be accurate.

The only Dreamcast games that had cue / iso files where the very early releases when there was a standalone boot disk.  Several months later, they figured out how to use the selfboot disk onto the same 700 meg cd and then cdi images were born.  This is probably why your cue file games don't work, as boot disk was needed.

The Dreamcast games themselves were ripped through the built-in Dreamcast modem.

There is a way to make non self boot Dreamcast games into self boot cdi, but honestly it's not worth the trouble as readily available gdi images are now.

Very few cdi games were the entire release, in fact Crazy Taxi was super small that they had to use fake padded sectors on the cdi image so that the game itself would be written on the outer edge of the cd so it would spin faster and play better on a real Dreamcast.

I went through this entire process of redownloading gdi and converting to chd earlier this year, and although it took a while to do, after converting to chd it saved a lot of space and provides nostalgia for the Dreamcast games that I purchased long ago.

 I also think it's not "faulty" CUEs either, because they work when you pointed LB to the CUE in the XML, so that tells us your CUE files do work but just don't convert.

I just meant faulty in the information needed for CHDMAN to convert isn't sufficient. Basic ones I had didn't convert but the following example converted fine:

That's an interesting explanation. Thanks for sharing.

@Headrush69 Can you also post the CUE of the one that didn't convert? If it's easy enough to identify what's missing, altering the CUE to what CHDMAN can work with is another way, albeit tedious. But an interesting experiment nonetheless.

No. Unfortunately my entire library is converted, that was just a new CUE/BIN I downloaded to double check. 

There is an interesting discussion on the MAME github about chdman and Dreamcast images here.

That discussion leads to some scripts here that might help the original OP in converting some CUEs to workable GDIs for conversion.

Go to that folder in Windoes, put *.cue in the window search and drag and drop the results to Launchbox to start the import wizard with the cue files.

Yes, that'll help build the library, but it doesn't do anything about the additional space requirement. In my testing it seems that CHD files are slightly smaller than ZIP files overall; my 800GB ZIP library would be roughly 720GB as CHD files. As uncompressed folders, however, it's 1.5TB.

Didn't know redump had their share of e-drama. Thanks for the link.

 

@Slag-O-Matic I gave you a whole slew of options you can do in the previous page. Did you decide on one?
