>>39419022I got to get to mirage island in emerald, which is insane because later I found out the chance to get there was one in millions.
The game invisibly generates something like 1 in 65000+ numbers at random every day and if it coincides with one your 6 team Pokemon personality value (5 random digits number unknown to the player), the island appears.
And the only worthy thing the shitty island has, is a shitty unusual berry.
