I'm using your program with emu control center (ecc). Like I mentioned before, I got whdload games to run within ecc using WinUAE Loader, but because ecc is crc32 based I am having problems. The way ecc works is that you have to add metainfo and images individually to each game (each having a unique crc32 value). Eventually I would like to complete metainfo (as an eccdat)and images (as an imagepack) for all whdload games and share these with other users. But for other users to use my eccdat and imagepack, their whdload games must have the same crc32 values as mine. we have compared the same games (#-A so far)and while most match, some do not. So I was wondering, if the games were unzipped they may have the same crc? Am I even right about this?
