In-game main menu is a bit useable. The main menu uses real data to populate character windows.

Items menu is partially implemented, and it also uses real data.
In the data installer, the following opcodes have been implemented: GOLDU, GOLDD, CHGLD, DLITM, CHITM.
Lua Scripts reformatted and documented. Inventory, money and bank access functions improved.
