Hi !
I just recently got to know there was such a thing as clrmame, to verify my mame collection.
And i thought i had many when i had like 4 gb of em.
So i started collecting, and finally one day i had all 4841 sets. The problem is that i still get tons of errors.

After doing a scan i first get a ton of "unneeded file..." entries, and after that i get like 300 different errors.
Mostly its missing roms (i thought i had em all ?) and "wrong CRC32"
Like half of the "missing rom" entries are in light-blue text, while the rest is in black.
Theres also some weird errors like
Winning Spike (ver JAA) [folder: winspike]
missing rom: 705a18.22h [size: 1048576] [CRC32: 0xeb97fb5f]
missing rom: 705a19.17h [size: 1048576] [CRC32: 0xbab84b30]
unneeded file: \roms\winspike\705a18
unneeded file: \roms\winspike\705a19

here it first shows i am needing a file, then it shows the file as unneeded ?
How can i fix these errors ? I followed the easy emu tutorial and made all my sets non-merged but all that did was eat like 6gb of my harddrive space.
Do i just have to keep downloading all the .zip files that theres errors with and hope i eventually get a good one ?
