Gen IV Tweaking patterns
-----
HOW TWEAKING WORKS

The game divides the overworld maps into 32x32-tile blocks called chunks. The lines between each of these chunks are called loadlines.
These loadlines are static in a specific Gen 4 games, but are known to differ in locations between Diamond/Pearl & Platinum.
Tweaking is a kind of movement that is performed across multiple chunks of the map, crossing these loadlines following predefinite patterns that alter the surrounding chunks, or at least how you'll interact with them.

CHUNK CONFIGURATION

1 | 2		1 : top-left chunk	| 2 : top-right chunk
