 === Overview ===
-CCI files start with a NCSD header which is 4096 bytes long, followed by 4 [[CXI]] blocks. While it is unknown what each CXI block is for, the second one is most likely the main program code since it is much bigger than the others.
+CCI files start with a NCSD header, followed by 3 [[CXI]] blocks. The first block usually starts at 0x4000. While it is unknown what each CXI block is for, the first one is most likely the main program code since it is much bigger than the others.
-The first CXI block always begins at 0x1000, and appears to lack a RSA-2048 signature. The offsets to the other blocks are found inside the NCSD header.

-CCI images may not include all four CXI blocks. For example, Ghost Recon: Shadow Wars lacks the third CXI. Entries at 0x130, 0x134 and 0x1A0 in its NCSD header are zero.
+Parts of the first CXI block's NCCH header are found around 0x1000 for whatever reason.
