MAME CHD Files

Hi guys.

I have question regarding arcade games CHD files.

I have full non-merged MAME 0.179 romset. I spent more than year to test/play all the games from this release. I left in LB only the ones that I enjoy to play. Now I want to delete from my hard drive all the other games (that I remove from LB) because of the size of the fullset. I this is where I find problems. 

If I understand correct one game needs only one zip file, so it will be easy to check for games that i left in LB what file LB is refer to for specific game and delete the other zip files (for games that I remove from LB). Is this correct? Or maybe some games used two or more zip files? (like I said I have non-merged version so all games are in separate files?).

Another (bigger) problem is CHD files because from what I read some games are using CHD files named different from zip file of this game, and LB only refer to zip file.

So the question is if there is some reference list where the games are assigned to CHD files? Are there CHD files used by few different games?

 

Any help will be appreciated.

Some chds have the same name as the game's rom while others don't, but all chds will be in unzipped folders named exactly like the game roms, making these folders easy to spot and remove.
For example the game Killer Instinct, kinst.zip uses a chd called kinst.chd which is in a folder called kinst, whereas the game Crypt Killer, cryptklr.zip uses a chd called 420uaa04.chd which is in a folder called cryptklr

Yes i'm pretty sure i have non-merged set. 

One more questrion - are there any clones worth playing? i always don't even import them to LB as i was thinking their just other language versions, etc. But now i hear that there are some decent versions of games like street fighter 30th anniversary version or something like that. please let me know what you guys think about it.

is there like thousends of those clones? i don't want to spend another year to play all clones just to add 4 or 5 good clones to my MAME collection.

Here is a list, made with clones worth playing (either for their gameplay, their addons from the original version, or for their 4 player vs 2 player version).
It was made by some of the users from the HS community some years ago, but the list is still current:

You may also come across games where the parent is unplayable but a clone is.
For example, as you're on MAME 179, the parent of the game Alligator Hunt is protected and becomes unplayable shortly after starting, whereas it's clone is unprotected and fully playable. The parent didn't become working until MAME 190 or thereabouts.

Also, since you've tried every game in your romset at least once, if you are going to delete quite a few chd based games you should also tidy up MAME's diff folder. These chd related data files can be big and add up to a nice amount of space on your hd.

Thanx spycat. The problem is that i would have to play all clones to find the ones that are playable instead of parent games which is too much for me. i don't have another year for that ;]

I understand i can delete all files from diff folder? delete files for games that i leave in my collection will recreate when i play those games again?
