/*
* CALCROM.CPP
* © PikalaxALT 2020-2021
*
* Permission is granted to copy and/or modify this code under GPL 3.0.
*
* Simple C++ executable to measure the completion rate of Nintendo DS
* reverse engineering (decompilation).
* Similar in scope to calcrom.pl from pret-agb projects, but designed
* to cope with restrictions imposed by the DS toolchain.
*
* Requirements:
* - Must have C++11 compliant compiler.
* - MacOS X: Must provide elf.h on the include (-I) path.
* - Must be placed in ".github/calcrom/".
*
* Changelog:
* - 0.1.0 (26 May 2020):
* Initial implementation
* - 0.1.1 (26 May 2020):
* Allow program to be run from wherever
* - 0.1.2 (27 May 2020):
* Extra security on ELF header
* - 0.1.3 (30 Jun 2020):
* Account for diamond/pearl split
* - 0.2.0 (30 Aug 2021):
* Support hgss
* - 0.2.1 (31 Aug 2021):
* Make calcrom more generic and configurable via command line
* - 0.2.2 (18 Sep 2021):
* Handle errors when paths are missing
* - 0.2.3 (10 Nov 2021):
* Refactor classes into separate objects to improve future maintainability
* Report hardcoded pointers
