Can I use the rebuilder to go through old rom sets to see If I have any missing? My first scan revealed a bunch of Bios missing as well as samples: Here is the log:

Missing Sets: 47 of 7186
Wrong SetName Case: 0 [0 fixed]
Wrong Named Sets: 1 [0 fixed]

Missing Roms: 1963 of 100819
Missing Bytes: 2gb of 59gb
Missing BIOS Roms: 18 of 125
Wrong Named Roms: 2 [738 fixed]
Wrong RomName Case: 0 [0 fixed]
Wrong Sized Roms: 18 [8 fixed]
Wrong Date/Time Roms: 0 [0 fixed]
Wrong CRC32s: 31
Wrong MD5s:
Wrong SHA1s:

I was suprised I was missing so many roms.

There is also an option under the rebuilder that says skip creation when file exists in ROm path. Is that to prevent duplicates or is that to prevent an older version from replacing a newer one?
