Ragefan informed me about his new software that works together with Offlinelist by Replouf66. The program can check the possible combinations of patches availables (remove intro , trim ff & 00 , specific ips patches ...) to find how to recover a good dump from a bad one , checking the CRC of good one in the .dat file provided by OffLineList .... The software can process a large number of roms into a given directory. It needs java to run. Visit the OFFICIAL GBA GOOD DUMP MAKER HOMEPAGE (too bad it's in French) and the Replouf66's HOMEPAGE to get Offlinelist.
