RPG Maker MV and MZ use a custom encryption/scrambling method for their assets (tilesets, faces, battlers, etc.). They take a normal .png , apply a simple XOR obfuscation, and save it as .rgmvp . rpgmvp to png
A: Yes—just reverse the XOR (apply the same script with ^= 0x29 again). Or let RPG Maker re-encrypt when you deploy your project. April 14, 2026 | Category: Game Dev /
Whether you’re modding a favorite RPG Maker horror game, recovering a lost sprite, or just curious how the sausage is made, now you have the tool for the job. Or let RPG Maker re-encrypt when you deploy your project
def rgmvp_to_png(input_file, output_file): with open(input_file, 'rb') as f: data = bytearray(f.read()) for i in range(len(data)): data[i] ^= 0x29 # The XOR key used by RPG Maker with open(output_file, 'wb') as f: f.write(data) rgmvp_to_png('character.rgmvp', 'character.png')
You see a file named HeroFace.rgmvp , rename it to .png out of hope… and nothing happens. It won’t open. Your image editor just shrugs.
A: Those are different (audio-related). This post is strictly for .rgmvp (image) files. Final Thoughts The .rgmvp format is a minor speed bump, not a brick wall. With a simple XOR decode, you can turn that “locked” file back into a usable PNG.
