You doing this on a Windows Operating System? You need to Custom Kernel Flash before drivers can be installed, to allow synching of Games.
Yes, it's on Windows. I'd done it but it's still not working. There was a warning that "kernel dumped but the MD5 checksum is unknown" (this showed up when flashing the original kernel too). I then chose to continue. But still, it won't sync.
Oh, I also want to say what a tremendous job what you did with the PSP core. I can imagine playing Crisis Core on a big screen!
