If you want Item ID's Greater than 100k you can change the max ID in Items.h
Code:
// MMF_EQMAX_ITEMS: Make sure this is bigger than the highest item ID#
#define MMF_EQMAX_ITEMS 100000
// MMF_MEMMAX_ITEMS: Maxium number of items to load into memory. Make sure this is bigger
// than the total number of items in the server's database!
//#define MMF_MEMMAX_ITEMS 32700
We had to change this on Dragon's Flight. Just update the values and recompile
