HELP WITH UNLAUNCH and TWILIGHT MENU

[NeedhelpDSIXL]

HELLO guys, i've installed unlaunch times ago and lost the sd used for that procedure...Despite this my dsixl still have the unlaunch when I turn it on, but there is not twilight menu. My question is: Can i install twilight now, even if i've already unlaunch installed in my dsi xl ? Do i risk something installing it ? Thank u guys
