The Magic Merchant and the Debug Armor

There is a mysterious NPC hiding somewhere in Rapadagna City who only appears under certain conditions. To find this NPC, start a new game, and get to Rapadagna without talking to the Sage of Save. Before meeting the Queen, jump off the wall on the right side of the palace entrance and check around the bushes behind the holy fountain. It may seem featureless, but if you have met the aforementioned conditions, you will find an NPC who calls himself the Magic Merchant.

The Magic Merchant will tell you he is here for debugging purposes, as he generously gives you a whopping 9999G every time you talk to him. Being a merchant, he has items to sell, which includes the Legendary Equipment normally sold in the endgame, as well as the Debug Armor (デバッグのよろい) for 1980G. Once you buy all his wares, he'll stop displaying the shop screen when you talk to him, and he'll vanish completely once you enter the next dungeon. Until then, talking to him will always give you 9999G, which can even push the money counter beyond 999,999G as the game has no discernible limit on money.

The Debug Armor appears to be the same as the Legendary Armor, giving the same +15 DEF stat boost, but when you check its description you will receive a prompt to raise Pepelogoo to any of the three available levels. You can use this item even if you don't have Pepe yet, which can lead to glitches ranging from inoffensive (incorrect sprites being loaded) to game-breaking (the game hanging as it doesn't know how to proceed), but the Pepe Fruit events can still proceed normally albeit with visual glitches.

WARNING: You can only obtain the Debug Armor in the original Japanese version and the 2012 official English version. The fan translations break the means of obtaining it in various ways due to messed-up pointers causing chunks of dialogue to be intentionally shortened, accidentally dummied or incorrectly allocated (the English hack never brings up the store screen, and the French hack just crashes violently when the store should appear).
