i'm currently adding the title system to my emulator and the packet title is like that
title 0.5 11.3
it's quite obvious 0 and 11 in the exemple are titleId but i can't find what the 5 and 3 stand for...
i've did multiple tests on official and it is always 1 3 5 7.
seems like every 2 the title doesn't show up.
NVM seems to be a bit flag
0=>selection invisible
1=>selection visible
3=>visible
5=>effective
7=>effective and visible
