I would also love the option of chd!
You know, I hadn't actually looked into this because it seemed weird (and mildly annoying, tbh) to have yet another PS1 disc format people use. I always thought it was strange since chd was usually used for things like Killer Instinct and other arcade games that utilized a HDD. It looks like the MAME crew made it applicable to more things and it gives better compression to boot! I'll definitely look into this!
EDIT
Looks like I've got pay dirt on the format conversion. It will be easier to do in the script than on-the-fly like I just did to one of my games, I'm really digging the compression ratio, so far. This will help more on the PSC, too. Thanks for the suggestion!
Code:
[USERNAME@USERNAME-home PSYCHIC FORCE 2 [J]]$ ls -lh

EDIT 2
I managed to wrangle some ugly-looking scripting to make the game titles capitalize every word instead of it being in all caps. It will hurt my copy editing brain going forward to see things like "The" in the middle of a title and the language brackets will be lowercase (so you'll see [j], [e], [g], etc for things) but it's not entirely off for other ROM tools and sets to do such things.
I suppose I can do one last sed to get that last part fixed.The language brackets capitalization is now fixed. Now titles will look like this:
Tokimeki Memorial Drama Series Vol. 2 - Irodori No Love Song - [2 Discs] [J]
instead of this:
TOKIMEKI MEMORIAL DRAMA SERIES VOL. 2 - IRODORI NO LOVE SONG - [2 DISCS] [J]
