    Does anyone know how to make the other tools like gimginfo work on large files (>2GB)? I downloaded the source code and tried:
    Compiling with gcc and the -D_FILE_OFFSET_BITS=64 flag for large files (no change)
    Changing the uint8_t in gimglib.c to off_t in gimglib.c (no luck)
    Changing the mmap in gimglib.c to mmap64 (no luck)

    I don't know much about C and how mmap works. Any ideas?

    By the way for POSIX systems (linux and maybe MAC) the patch is:
    Code:

    Your question is somewhat confusing. For Windows, the current version of Fast Image Unlocker can already handle files greater than 2GB. I used it to unlock Europe 2012.30 for my unit. The linked version of Garmin Image Unlock in post 1 also can handle files greater than 2GB. So, are you trying to compile Garmin Image Unlock for something other than Windows?

    Yes, Linux. That's why I mentioned how to patch the source for the unlocker for POSIX systems. The 32bit barrier for some of the other tools that need gimglib.c appear to be more difficult to patch and I've mentioned some of the things I've tried but the mmap call (in gimglib.c) fails on files more then 2GB.

    I have a GPSMAP 640 with a purchased bluechart G2 SD card. I've tried to copy this SD card using the key generator, map ID, etc and generating an unlock UNL file as detailed in other tutorials but can't get the copy to work. It always comes up "can't authenticate map". Will this program unlock the gmapsupp.IMG file on this SD card and will it work without a UNL unlock file in my 640?

    No need admin rights, just drag the .img in gimgunlock.exe , tested working with new Transalpin map (Windows 7 x 64), you can see my 62 screens in Transalpin 2012 thread.

    Not to mention interrupt the thread. Does no one know how to patch the gimglib.c to work with files >2GB?

    I'm pretty sure my patch for the unlock tool (gimgunlock) should work for MAC too. Any mac users try it? It worked for Linux.
