This is actually quite a simple program to use. Everything is readily available in friendly, simple dropdown menus. First, select the store you want. Then select from the dropdown menus which items you want to have for sale. (Prices are handled in PK Hack.) The only major drawback to this editor is the fact that it uses a predetermined list of item names and not the ones in your own hack. So if you forget which items you changed into what, you'll have to go into PK Hack, get the item number, convert it to Hex using your Windows Calculator, and put it in the Store Editor. (You can do that with the Unlock Numberlists function found under the "Options" menu.) That's about it!
