This thread is part 1 of “RPGM 3: Declassified”, a series of posts containing some discoveries I made regarding RPG Maker 3.

Cheat code

There’s been a cheat code hidden in the US version of RPG Maker 3 for over 20 years. Enter “RPG Maker” in the author field of Storyteller settings. You’ll unlock some background images from the Japanese version of the game. You’ll also unlock the “hidden” category. This contains 99 images of concept art featuring monsters and characters. This cheat code also exists in the Japanese version. I found it on a Japanese cheat code site a while ago and wondered if it worked in the US version. It did!
