My One True Love

[Nakamichi]

I am so desperately in love with the CHD format.
A single file for everything, no .cue files ever, optimized for streaming data and compressed.
... Id marry it if i could.

And here's my ONE [1] True Lve.

Doesn't iso do that already ?

CHD holds compressed chunks of data and are meant to be a lossless format for preserving disc images. I do not like them as a general format as opposed to ISO because of its lack of accessibility (it's more designed for emulation). It also means you have to manually convert them back to ISO before they can be burnt to disc or opened with readily available disc image tools.

True, as I had to look up CHD to see what he meant.

So they basically and DD if=/device of=/target/disc.img without compression ?

Nope. You cannot mount them normally or use the 'dd' tool in Linux to create it, it has to be using the 'chdman' utility to convert them to be able to mount them in virtual drive software, which is quite a bummer. There's some technical specifications on the format from the MAME GitHub if you're curious. https://github.com/mamedev/mame/blob/master/src/lib/util/chd.h

true, only ever really used them for emulation, dont see the need elsewhere... but for emulation its a godsend.
So many great games, much less space, only ever one single file.
i love CHD

So CHD files include whatever BIOS files or anything else the game needs to run?

no. CHD files are just compressed disc games for emulation.

Only poor pirate plebs use compression to store data ;o;
