Item IDs

In the vanilla game, the most common items have an ID that is written to $7E2391 with amount in $7E2393. The script then calls common "loot" routines 0x39, 0x3a that gives the player that item. For randomization we want to convert all items to such IDs, so we extend the routines.

Vanilla item IDs

see Data Crystal RAM Map -> Prize ID list

Added item IDs

see patches/gourdomizer_drops.txt for implementation
