+
+// 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 NDEBUG before release, however this has been changed as
+// Ruby's actual debug build does not use the AGBPrint features.
+#define NDEBUG
+
+// To enable print debugging, comment out "#define NDEBUG". This allows
+// the various AGBPrint functions to be used. (See include/gba/isagbprint.h).
+// Some emulators support a debug console window: uncomment NoCashGBAPrint()
+// and NoCashGBAPrintf() in libisagbprn.c to use no$gba's own proprietary
+// printing system. Use NoCashGBAPrint() and NoCashGBAPrintf() like you
+// would normally use AGBPrint() and AGBPrintf().
+
+// NOTE: Don't try to enable assert right now as many pointers
+// still exist in defines and WILL likely result in a broken ROM.

+#endif // GUARD_CONFIG_H
