You mean the color, and UI stuff file from the rpg maker? Unfortunately, not yet. Most assets are compatible with RMMV and MZ tho
From what I understand only this package "https://clockworkraven.itch.io/raven-fantasy-pixel-art-tileset-green-buildings" has no compatibility. Is this correct? All the ones I'm really looking to buy have the RMZ and RMV logo right at the top, I assume that's the way to know they're compatible.
