Is it safe to upgrade to F/W 4.1 with a soft modded Wii?
Version 4.1 of the System Menu was built on June 24th, 2009 and released on July 3rd, 2009.
Apparrently,  there is a bugfix whereby if a VC/WiiWare game is played from SD, and then Wii Sports Resort is played, it forces you to watch the motionplus tutorial, although it was meant to be only watched once, on the first run.
Also if your really interested in still updating then here is a link to...
