Bit of a warning:
This version's running like absolute ass in both Windows and Linux, but thankfully the old trick of overwriting all the default RPG Maker MZ NW.js files with the latest version from the NW.js website seems to work. For some reason MZ's only packaged in version 45, which is 29 versions and three whole years out of date.
With each passing year my hatred grows for Chromium and the lazy, bloated, half-assed "cross platform" deployment method it's standardized. I don't blame the dev, I blame RPG Maker and Google.
