Megaman Zero 3 - Unlocking Minigames with Battle Chips

So, fun fact:
Megaman Zero 3 lets you unlock the mini-games based on the 4 Guardians through the Battle Chip Gate as well!
-Blue Moon Ray unlocks Leviathan's
-Meteor Red Sun unlocks Fefnir's
-A chip with an even numbered-ID unlocks Harpuia's
-A chip with an odd-numbered-ID unlocks Phantom's
What makes this even more interesting, is that this function works even with non-Japanese copies of the game. Also, the chips used in question were the Blue Moon Ray, Meteor Red Sun, the Iceman Navi data chip, and the Aquaman Navi data chips, which means the chips released for EXE 4.5 work too!
So, if you're playing the GBA version, and you're struggling with the S-Rank and Saber/Buster-only run requirements, you can use this method to unlock the minigames too!
