→6.1.0: details on changes
Creport takes a string containing a pid formatted in base10 as input, and generates an error report. This error report can later be sent to the cloud server by [[Eupld services]].

[2.1.0+]: An additional input argument string is now used. Only the first byte is used: <code>inarg_flag = u8 inarg[1][0];</code> This is compared with '1' only with the below titleID code, and near the end of nnMain().

[2.1.0+] It also blacklists the creport-sysmodule title-id. Then, if inarg_flag(see above) is set to '1', all title-ids are blacklisted except for the following whitelist:
* 0100704000B3A000 "Snipperclips" (Game)
* 01007EF00011E000 "The Legend of Zelda: Breath of the Wild"
* 01009B500007C000 "ARMS"

This is probably because of privacy concerns (software keyboard + browser could contain passwords and personal info).

The above whitelist handling is probably so that only Nintendo (published) applications get full exception info reported, since crash-reports for other applications probably(?) wouldn't be shared with third-parties.
For all other title-ids, it generates a random AES-128 key and CTR using <code>csrng</code>.

** <call func> here is throw_fatalerr(ptr+4). The above second block basically changed the conditions required for throwing fatal-error. For example, fatal-error is no longer thrown when applications(?) crash.

== [[2.3.0]] ==
Exactly the following code was changed:
Only change was adding a titleID to the above whitelist.
== [[5.0.0]] ==
Many changes were made to add more detail to reports. In particular:
* The second input flag is no longer actually used, instead whether the process is an application is parsed from the ATTACH_PROCESS debug info.
* Support was added for reading a custom user error code from process memory in the UserBdsak case.
* Support was added for reading a custom user "Dying Message" of up to 0x1000 bytes from process memory if the crashes process was an application.
* All reports now have additional info in their crash reports:
** A list of up to 0x60 threads is retrieved via svcGetThreadList, and each thread has a full register dump + stacktrace added to the report.
** The crashing thread's PC and LR are used to try to locate the base executable region that caused the crash -- if found, it and up to 15 code regions with higher virtual addresses have their start and end addresses saved, and their executable name and GNU build IDs read out of .rodata and added to the report. This fixes the problem of crash reports in previous versions not including information on ASLR.
== [[6.1.0]] ==
Support was improved for detecting code regions. In particular:
* The number of processable code regions was increased from 16 to 96.
* Instead of processing the crashing thread's PC or LR, now both are processed, and additionally every address in the thread's stacktrace are processed.
** If the crashed module is an application, this is further done for all threads.
