How to edit items, Not too hard but here is how.
On the editor you will see 4 different types of edit boxs, Slots, Slot Amounts, End of items and Item Master code. Here is what each is

Slots 1 .. 20 : These are the actual items you own or wish to have, all you do is enter the item digits (found i the acompanying file named 'Digits')

Slots 1 .. 20 Amount : These are the number of items you have in the slot, Eg if you put 01 in slot 1 and 99 in slot 1 amount you will have 99 master balls

End of items, this is only there if you wish to fill all 20 slots with items, if you do then you muct type '255' in this box, otherwise leave alone.

Item Master Code : This is the TOTAL number of items you have, just add up all the slots that have items in them and type the number in this box, For instance if you have 10 different items then type 10 in here.

 

Now for the tricky part... in the slot following your last item you MUST put '255' to tell the game "Items End Here" for all those who used gameshark codes for items will know that! so if your last item is in slot 15 then in slot 16 put '255'.
