I stumbled upon this recently. Pretty amazing frontend. You start the emulator directly while choosing the rom. http://www.camya.com/eccblog/ Has a build in CRC32 handler en checks an online database for the latest information. (similar to the redump.org database) Register on the foum and get the latest WIP. Worth a try.
Just import your redump.org DAT file, choose the directory were your games are located and your are set to go
