I just now realized there was a new version of RomCenter today so I upgraded, but now I'm confused. The available list is a lot different than the game list inside of FBA. For example, instead of having 1941 World and 1941 Japan, the dat file states that only the Japan version exists. This had a huge impact on my collection, cutting over half of them to either missing files or unknown games. It seems weird that the older version of RC told me that all of them were good and then using the same dat file in the new version just wipes them out. Any ideas as to why it's different?
another example: 1945kiii is listed as unknown in the dat but contains the exact same CRC files as listed under game information in FBA.
I really hope it's not a RomCenter problem; I don't know what I'd do without it...
