Transparent menu background

[Welko 1]

I am changing the menu architecture of my game trying to make a small menu on the corner and I want to make the background transparent.
 
This is the change I made related to this purpose:

class Scene_Menu
 def main
  @background = Spriteset_Map.new

I added @background.dispose and @background.update as well

The problem is I am using Pictures to make flashlight effect and dark and they appear above the menu, making it difficult to see the window.

The game is in Brazilian Portuguese, by the way.

How can I fix this?

looks like spriteset_map draws pictures in viewport2, with a z value of 200.

try changing that z value, using:

class Spriteset_Map
attr_accessor  :viewport2
end

then, in your menu do

def main
  @background = Spriteset_Map.new
  @background.viewport2.z = [ some number. I'm guessing 1~99 will do ]
...
end
