I also use this for my project with MZ,
basically I just move all the tilesets and just move them to a tileset template which would be easy to do if you turn on "GRID" and put the settings on 48 x 48 pixels.
ok it has been 8 days since I buy this pack and apparently there are some optimization you can made for RPG MAKER series.
it is actually possible to use animations with RPG MAKER engine for the grill, tv, bath stuff, etc.
just letting you know that you can make the "animations" into "characters" for the RPG MAKER series to use animations resources in RPG MAKER series. (some optimization have to be made)
