Comment (by njustn at gmail.com):
absolutely, I'm actually on campus right now so I can't get the file to
you immediately, but I've looked into it further and it looks like I may
have been wrong about it affecting all systems, but I'm completely sure it
affects snes roms.
Since zsnes was working I downloaded the source for that and found where
the CRC is being calculated and it looks like they do one thing that might
be making all the difference, it detects the type of info header on the
rom, and sets the month and day to 0x42 and 0x00 respectively, after which
the correct CRC is produced.
I'll provide the information you requested as soon as I return to my
appartment ~ 1.5 hours.
