If you are not compressing your iso files using .chd format, you are doing it wrong, completely. This is how you emulate in current era. Here you are a couple of tutorials on how to compress you crap.

https://wiki.batocera.org/disk_image_compression
As a reference, Dead of Alive 2 gdi file is 1,2GB compared to 232MB in chd form.
Also, if you aren't using m3u files to manage your multidisc games, you are doing all wrong. Here is the tip https://github.com/Jetup13/Retroid-Pocket-2-Plus-Wiki/wiki/Emulators-and-Formats#m3u-files

You misunderstood everything. I coerced my .gai files into .chad pants.

Gamecube images are the one thing you shouldn't use CHD for.
Use RVZ instead.
Dolphin has an integrated converter, to easily convert your library to it.
im fine with 7z compression for storing disk based images
This. I keep eveyrthing onn a storage drive and just transfer over and unzip what I want to play.
LZMA compression is too resource demanding to use on consoles. FLAC is ok. CHD needs Zstandard or LZ4 support ASAP
Do you have to do anything special to decompress the CHDs? Because I compressed all my Sega CD games to chd, then I decided to be that guy and burnt a few of them to disc, and the bin/cue files didn't work on real hardware after being uncompressed. I had to actually redownload them to be able to burn them. One of the best points about CHD was that you could just convert them back and they'd work flawlessly, but in my experience that has definitely not been the case.
> deeeeeeerrrrrrrr just destroy your ISOs and never be able to burn them onto real media or use them on real hardware ever again
you're a fricking idiot, op. possibly the worst kind of fricking idiot.
chd is only useful for emulation
And emulation is what this thread is for, moron. Read the OP again.

Thanks OP I got an 8TB drive and plan to download/archive romsets so if rom sites die off I'm secured.
I will keep my games uncompressed so that I may extract music from them without any extra steps.

For me? it's .PBP format.
Compressing was done to save space when we had limited hdd space back then.
Currently there is no need for it since we can use the unzipped image at any time saving space and CPU isage,also not supported by lot of emulators.
I tested some of my own rips with chdman verses straight 7zip and the 7zipped isos were smaller.
Compressing to CHD makes it impossible to verify Redump/Tosec images since the original hash is lost, so it's shit as an archival format.
what are the pros/cons for cd file types?
personally I prefer everything in iso.
bin+cue can be annoying. especially if you need to fix the cue file or have one with multiple bins.
ISO doesn't have audio track data. Bin/cue is best for CD images. Since DVDs have no audio tracks, ISO is perfectly fine for them. And if you want to be a turbo autist about it, ccd/img/sub is the most complete for CD images, but since redump only does bin/cue, that's the preferred format.
>ISO doesn't have audio track data
Frick. This explains when I wanted to do an iso dump of the second disk of AVP'00, which is of course just the music.
I just use the Emulation Wiki to see what compressed ISO format I should use for what console. I try to go for formats that would work both on emulators and the actual hardware instead of just one or the other.

GameCube in particular is a b***h since there are many games that break if you trim them, but without trimming them they will all take up exactly 1.4GB even if the game is 100MB or less.... and some that will work fine if trimmed with one program but not the other, and vice-versa.
PS2 is also somewhat annoying in that all of the compressed formats either work on OPL, or PCSX2, but none of them work on both. (Although ZSO support is coming to OPL... but it's buggy from what I recall).
>GameCube
Use NKit and you can trim the padding without compressing them and they'll still work on original GameCubes and Wiis. It's different from the old trimming methods that only worked sometimes. You can also convert them back to the byte-for-byte original ISOs as long as you keep the trimmed partitions (though it will automatically dump the padding partitions to a subfolder in NKit and they can also be found online). Space savings are insane, all without compression.
>This format has been deprecated in favor of RVZ. (Developer's Wiki)
>Playable on Hardware? GC: Yes (ISO variant only) / Wii: No
According to that Wiki
That info is incorrect. NKit ISOs work on original GameCube + SD2SP2 adapter and on Wii using Nintendont with either SD or a USB drive. I've personally played them on both myself. There are some USB loaders on Wii that it might not work with, but Nintendont is what you should be using anyway.
As for RSV, it's not usable on original hardware. Dolphin only. So ultimately it depends on what you'll be using them with, but NKit is still king for original hardware, and I guess RVZ for Dolphin.
I should add that streamed audio works as well, which was something that didn't work in some games with the older trimmed format (ie, the opening blurb of Eternal Darkness).
I have over 100tb of storage why would I need compression
No thanks, original hardware/ODEs don't support those.
i just dont care
