From Menu to TitleScreen when use ModularMenu from Luka S.J.

# TitleScreen
MenuHandlers.addEntry(:TITLE,_INTL("TitleScreen"),"menuOptions",proc{|menu|
scene = PokemonSave_Scene.new
screen = PokemonSaveScreen.new(scene)
menu.pbEndScene
menu.endscene = false
if screen.pbSaveScreen
menu.close = true
$game_temp.to_title = true
if $game_temp.to_title
$scene = pbCallTitle
return
end
else
menu.pbStartScene
menu.pbShowMenu
menu.close = false
end
},proc{ return !$game_system || !$game_system.save_disabled && !(pbInSafari? || pbInBugContest?)})

thats the one with save

# TitleScreen
MenuHandlers.addEntry(:TITLE,_INTL("TitleScreen"),"menuOptions",proc{|menu|
$game_temp.to_title = true
if $game_temp.to_title
$scene = pbCallTitle
return
end

},proc{ return true })

thats the one without you can decide wich one you would use but i recommend would use that with the save function.

"menuOptions" is the icon you can make your own one.
