For the windows, I think you have to put Rpgmaker VX ace Run time package, it's a pack of graphics for the default Rpgmaker VX Ace but for some reasons some games don't come up with that thing. You have put it in the game main folder where the "Fonts", "Audio", "System" and "User data", trust me just put it in there and it will do the magic but I use joiplay as the emulator so it should probably works fine.... I guess. Should give it a shot tho.
