I byte swapped my No-Intro collection of N64 games to use with Cen64. Apparently this was enough to not recognize the games in the RetroArch library anymore.

Yes, RA's detection is based on CRC checksums, so swapping byte order will indeed break it, as the checksums will no longer match.

So, in the future, users will have to choose bettwen Cen64 compatibility and RA detection? That could become a big issue if @tj90241 gets Cen64 to fullspeed.

Heh, that's a pretty big 'if'. However, if that comes to pass, we can add additional databases pretty easily. We'll just need a working set to run CRC hashes on.

This is not really a RetroArch issue anyway, no-intro is the defacto standard now (not byte-swapped no-intro). They aren't doing everything right but it's pretty much what people will use and keep using going forward.

CEN64 should support no-intro I guess, as for scanning in RetroArch, we'd just need a db of "byteswapped no-intro" crcs.
