 #ifndef GUARD_CONFIG_H
 #define GUARD_CONFIG_H
 
+// 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.
+
+// To note, Ruby/Sapphire likely did not use AGBPrint. This is because
+// the german debug ROM of Ruby did not have any uses of AGBPrint and
+// the assert commands but instead a "crash" screen. This config exists
+// for convenience for the user of pokeruby and NOT because it is
+// authoritative. These additions are for user convenience based on
+// officially recommended SDK practices for debugging and is therefore
+// still in part authoritative.
+#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().
