About WireWorld
WireWorld has 4 states:
space – represented by black
wire – represented by gold
spark – represented by red
tail – represented by blue

Spark changes to tail.
Tail changes to wire.
Wire changes to spark if it’s surrounded by 1 or 2 sparks.

Even with so simple rules, it’s able to implement many stuff in it.

Changes:
+ – added
– – removed
* – modified
/ – bugfixed
! – important

0.3:
+ ADDED LOADING (and saving)
! sorry, but saving is buggy. I don’t want to work on WireWorld DS anymore though.
