Vagrant Story/RAM map

The following article is a RAM map for Vagrant Story.

This is a list of VRAM addresses from the US version of the game (SLUS-010.40).
This is how memory is organised when in game. A different memory layout is used when the opening
sequence and title screen are being displayed. The RAM map is split into two parts the first deals
with data while the second part deals with code, each part is independantly listed sequentially
though the data and code are actually interweaved.
