// In the Generation 3 games, Asserts were used in various debug builds.
// Ruby/Sapphire and Emerald do not have these asserts while Fire Red
// still has them in the ROM. This is because the developers forgot
// to define NOAGBPRN before release, which is actually supposed to be
// NDEBUG, however this has been changed as Ruby's actual debug build
// does not use the AGBPrint features.
#define NOAGBPRN
// NOTE: Don't try to enable assert right now as many pointers
