This is also the first known title on retail which uses stack cookies. This is used by main-codebin, the ssp functionality in sdknso is still not used other than being called from an initialization func. This is implemented in the main-codebin as follows:

* The global u64 __stack_chk_guard is loaded then saved immediately before {first saved register} on stack, during func entry. During func exit, the global u64 is compared with the cookie on stack, it will call __stack_chk_fail on mismatch. __stack_chk_fail just executes an undefined instruction to trigger a crash.

* TODO: initialization

* There seems to be no (?) initialization func for __stack_chk_guard, it's just a hard-coded constant: 0xDEADBEEFDEADBEEF.
