Nonsense
a) diskspace doesn't matter. In times of terabyte hds and laserdisk chds you talk about a minimum saving
b) chds ARE zip compressed already. CHD is a container for raw data which is sector wise zlib compressed
c) it's a memory hog if you keep chds compressed. You won't be able to run them fine in MAME (except the small ones). Great idea to zip a 15GB file which needs to get decompressed into memory when loading the game and then needs random access on it.
To sum it up: zipping chds is nonsense.
