Storm Island Version 6.0 is now available over at @JimmyKazakhstan 's website: http://jimmysstuff.tk/index/wii_sports_resort_storm_island_download/0-11

Here's the description of the update:

New Option :

Bonus Content : This feature lets you use stuff that I worked on at one point but scrapped due to lack of interest, I thought it might interest you.

Revamped Menu

Custom Golf Courses: The Storm Island Team managed to make the first 2 custom Wii Sports Resort Golf Courses! One of them is over Resort Hole 1, and the other is over Classic Hole 1. You can't complete it due to how the game applies collision culling to the cup. We are working on a fix for that but for now, the courses are for show.

510 Wind is back! Updates to Out of this World mode in golf.

Custom Swordplay Showdown Stages

This also brings in two new categories in the Level Leaderboard, which are Swordplay Showdown - Custom Stages, and Golf: 1 Holes (Custom)
