Same error for me:
"Xdelta3: target window checksum mismatch: XD3_Invalid_Input"
I tried without spaces, different names for output file, with a newer version of delta, I tried dowloading the firmware this tutorial and from the official page again and can't patch the firmware.
Any ideas?
Thanks.
they need to have a strong line up on the launch titles too. I think they should move metroid prime 4 to the next console because by now it has been quite a while and there's no release date scheduled yet
