Just curious how ROMs are zipped

(1/3) > >>

MPTech:
When I look in my ROM folder, I have 3217 zipped files (I removed the CHDs), but in MAME it says I have over 6,000.
How does that work and is there a way to change the name in the display list (I'm running MAMEWah).

ahofle:
You probably have 'merged' sets, which means that parent and clone ROMs are all in the same zip file.  I'm sure you can setup MAMEWah to ignore clones.

stan2323:
Is it possible to unzip ROM and use them like that or should they stay zipped to be used.  Would they run faster being unzipped?

No.... Mame requires the roms to be zipped in order to work. Other emulators mostly use zipped files as well.  They unzip them and read the code into the emulators working space... They won't run that code any faster zipped or unzipped.

MPTech:
Thanks!  That explains the size.

Now, can I change the names? some of them have a name 50+ letters with all kinds of code on the end I don't need. (I know most of the country codes and eliminated a bunch of dupe stuff a long time ago). :dizzy:
