Just curious how ROMs are zipped
Turnarcades:
This might be the wrong place to go into the details of rom structures, especially with the billions of MAME-based pages available out there.
To put it bluntly, don't mess with roms too much unless you know what you are doing in MAME. The roms are designed by the dev team to show a certain way for a reason - to correctly catalogue the dumps MAME emulates. Other emulators are nice and easy, you just change the filenames, but trying to get the same uniform list with MAME is more ball-ache than it's worth.
Try the MAME website for answers first - they're bound to have more answers anyway as they wrote it.

Good enuf, I'll leave it as-is! It works, I shouldn't mess with it!

Since this is a MameWah question and not a mame question, and I've never used MameWah, there might be better ways of doing this, but...
I think you can go into the mamewah\files\mame-0.lst file and edit the line underneath the rom zip name. Make sure you do not change the zip name. (I'm assuming you had MameWah generate the list? With list_generation_method set to rom_folder_vs_listxml? Then MameWah is getting the list from mame -listxml, which means the name in the list is the game description.)
Example:
1941
1941 - Counter Attack (World)
1990
Capcom
Raster
Vert
joy8way
Status Good (Good)
Color Good (Good)
Sound Good
1942
1942 (set 1)
1984
Capcom
Raster
Vert
joy8way
Status Good (Good)
Color Good (Good)
Sound Good
1943
1943: The Battle of Midway (US)
1987
Capcom
You can edit the bold lines.

I could have sworn MAME works with them unzipped. It's just a big waste of space though.

M.A.M.E. does work with unzipped ROMs, but the ROMs must still be place in folders within the ROMS directory that are labeled the same as ROM set zip would be.
So instread of having .\Mame\Roms\1942.zip you have a .\Mame\Roms\1942\
Extracting all the zips may infact slow your system down, because instead of the file system on your hard drive having to store index infromation for just under 7,000 files, it would have to store information for almost 100,000 files and 7,000 directories.
ROM sets containing large ROM load quicker if they are not Zipped, the difference in load time is too small to notice for most ROM sets.
I store all ROM sets with CHD, unzipped in folders containing both the ROMs and CHDs, all other ROM sets are stored as Zips.
