Wai Wai World 1 Scroll Fix
2010 KingMike

One feature of this game is that the camera will only scroll
when the player is a quarter of the way from the edge of the screen.
While this limitation may have been put in place for the 2-player
co-op mode (so that both players don't have to stand so close together),
it is kind of frustrating in single player mode, as it leads to making
blind jumps.

So, this patch will center the camera.
I have just briefly tested this in 1 and 2-player mode.
In 2-player mode, it will scroll as either player approaches the center,
but will stop if the other reaches the one-quarter boundary.

If you want to use a Game Genie for the same effect on a real console,
the codes are below.

Since this code is in the fixed ROM bank, a 6-letter code should be fine.
EETILY (add EG to the end for an 8-letter code)
EAOIVA (add AG to the end for an 8-letter code)
The two codes change these two bytes:
$1D7F3, from $C0 to $80 (right scroll X-coordinate)
$1D826, from $40 to $80 (left scroll X-coordinate)
