Post Content: Sí, encontré un tutorial y me dí cuenta que estaba MUY mal xD. Logré hacerla, así fue el código, pero no sé si conoces una manera más sencilla :D

[SPOILER="Código"]
class My_window_scene #Scene Class
def update #Update sprites in scene
pbUpdateSpriteHash   [MENTION=24071]Sprite[/MENTION]s)
end

def pbstartscene(maintext,imgpath)
   [MENTION=24071]Sprite[/MENTION]s={}
@viewport=Viewport.new(0,0,Graphics.width,Graphics.height)
@viewport.z=99999
   [MENTION=24071]Sprite[/MENTION]s["background"]=IconSprite.new(0,0,@viewport)
   [MENTION=24071]Sprite[/MENTION]s["background"].setBitmap(imgpath)
   [MENTION=24071]Sprite[/MENTION]s["background"].x=(Graphics.width   [MENTION=24071]Sprite[/MENTION]s["background"].bitmap.width)/2
   [MENTION=24071]Sprite[/MENTION]s["background"].y=(Graphics.height   [MENTION=24071]Sprite[/MENTION]s["background"].bitmap.height)/2
   [MENTION=24071]Sprite[/MENTION]s["overlay"]=BitmapSprite.new(Graphics.width,Graphics.height,@viewport)
pbSetSystemFont   [MENTION=24071]Sprite[/MENTION]s["overlay"].bitmap)
pbDrawText(maintext)
end

def pbDrawText(maintext)
    overlay   [MENTION=24071]Sprite[/MENTION]s["overlay"].bitmap
    overlay.clear 
    marginLeft=112
    marginRight=96
    baseColor=Color.new(72,72,72)
    shadowColor=Color.new(160,160,160)
      drawTextEx(overlay,marginLeft,96,Graphics.width-marginLeft-marginRight,8,maintext,baseColor,shadowColor)
end


def pbMain
loop do
Graphics.update
Input.update
self.update
if Input.trigger?(Input::B)
break
end
end
end

def pbEndScene
pbFadeOutAndHide   [MENTION=24071]Sprite[/MENTION]s) {update}
pbDisposeSpriteHash   [MENTION=24071]Sprite[/MENTION]s)
@viewport.dispose
end
end

class My_window
def initialize(scene)
@scene=scene
end

def pbStartScreen(maintext,imgpath)
@scene.pbStartScene(maintext,imgpath)
@scene.pbMain
@scene.pbEndScene
end
end

def pbmy_window (maintext,imgpath="")
imgpath= "Graphics/Pictures/mailAIRMAIL" if imgpath=="" 
scene=my_window_scene.new
screen=my_window.new(scene)
screen.pbStartScreen(maintext,imgpath)
end
